A couple of weeks ago I reported with barely contained glee that winter was on its way. I was right. We got a few inches of additional snow this past week, and for the time being it is sticking around. Thursday night temperatures plunged into the single digits in the western part of the Upper Peninsula. The cross-country ski trails at Michigan Tech are open, and I plan to be out there on Saturday. It’s a good time to make sure I have all the right gear, or at least remember where I put it at the end of the season last year. It’s nice to have the ski season start a little early for a change.

Saturday is also Veterans Day, and so in what has become a bit of a tradition I would like to recognize those members of the ECE Department who have served in the U.S. Armed Forces:

Glen Archer
Mike Chase
Roger Kieckhafer
Chris Middlebrook
Mike Roggemann
Mark Sloat

I thank these gentlemen for their service to the Nation. I also want to acknowledge these individuals for their service to the ECE Department in their current civilian careers. I try not to do this too much, but on those occasions when I need to ask people to put the interests of Michigan Tech and the ECE Department above their own personal interests, they have always answered the call, and I am deeply grateful. They serve as an example for all of us.

We are in the middle of preregistration for the Spring 2018 semester, and because we are in the second year of an increase in the number of new ECE students, we are seeing particularly large enrollments in key sophomore courses like Digital Logic and Circuits II. Right now Associate Chair Glen Archer and I are working to make sure that we put the right instructors in these courses, and even though we still have a couple of question marks I am confident that these courses will be expertly taught. I have always been a big believer in putting our best instructors in these critical early courses, where pedagogy matters as much as the material.

I have to believe that the increase in enrollment is due in part to increased awareness of the demand for computing professionals, exemplified by the data I showed last week. Judy Donahue, our academic advisor for the BSEE program, tells me she has been processing an unusually large number of requests for transfers into the ECE Department. I’m not really surprised, but we will have to make sure we are prepared to offer our new students everything they are looking for. Coincidentally, just as I was preparing to write this, I got wind of a recent report from the National Academy of Science about the growth in Computer Science enrollment and what universities all across the country are doing in response. I am looking forward to reading that and sharing some of it here. The topic fits squarely within the interests of our Computing and Information Sciences Working Group, which has started its own study of how computing is approached, as a broad academic and research area, at 40 U.S. universities.

November 10 is the anniversary of the sinking of the Edmund Fitzgerald, in 1975. I’m not sure what that has to do with anything else in today’s column, but I suppose I can use it as an opportunity to remind everyone to be careful while traveling, especially a week from now when people take off for Thanksgiving. I don’t know anyone going out on Lake Superior, but the roads can be a little dicey this time of year with fresh snow. Take it easy and don’t get in a hurry!

I have mentioned before the old canard that there are two seasons in the Upper Peninsula: Winter’s Here and Winter’s Coming. While this obviously does not do justice to our beautiful summers, there is definitely a Winter’s Coming season, and it just arrived. After a rather late, warm, and wet fall, we had a storm blow through here on Tuesday with cold rain and 50-60 mph winds that was like a shot across the bow. Although the landscape is still dotted with a few bright yellow trees that weren’t quite ready to quit, for the most part our woods are bare. The forecast now includes rain/snow mix and other reminders of what’s to come. It’s the time when we put the driveway stakes in the ground, tune up the snowblowers, and make sure our snowplowing contracts are in place.

The change of seasons coincides as it often does with a change in the vibe in the ECE office. For some reason, it seems that the first half of the fall semester is just frenetic, with one deadline after another and lots of visitors who like to come to campus during that short window of time when the fall colors are at their peak. This year was made even a little more hectic with our ABET accreditation visit earlier this week. (I’m not supposed to tell you how that turned out, so I won’t.) Now all of a sudden it feels like we can take a little bit of breather. More importantly, we can turn our attention to some important longer-range issues that keep getting putting off on those days when all one thinks about is the agenda for tomorrow’s meeting.

The biggest long-range project on my plate this year is leading an effort to look at the role of computing at Michigan Tech. Before describing that further, I should give some context. This year we are looking at a major transition in the leadership at Michigan Tech, with ongoing searches for the president and the deans for four out of our five academic units: the College of Engineering, the College of Sciences and Arts, the School of Technology, and the School of Forest Resources and Environmental Science. This is not the result of any crisis, but just a bizarre coincidence where everyone hit retirement age at about the same time. The “last man standing” is Dean Johnson from the School of Business and Economics (whose first name really is Dean, leading to no end of jokes and explanations.) While it is difficult to predict exactly what will happen, I think it is safe to say that Michigan Tech will look a lot different at this time next year.

Back to the computing initiative. For many years, a number of people, both on-campus (including me) and some key external advisors have been looking at Michigan Tech’s position with regard to computing and information sciences, and wondering what we can do or should do to elevate our impact and our visibility in this key technology area. For several years now I have been a part of the Alliance for Computing, Information, and Automation (ACIA) which brings together the ECE Department, the Department of Computer Science, and the School of Technology, as we look for ways to cooperate in our academic programs and collaborate in research. The most successful outgrowth of that partnership has been the establishment of the Institute of Computer and Cybersystems, a research center led by CS department chair Min Song. However, there is more to be done, and with the upcoming transitions at Michigan Tech now is the time to do it.

In April of 2017 I made a presentation to the Michigan Tech Board of Trustees on behalf of the ACIA, where we made the case that computing is a key technology driver in the 21st century and that Michigan Tech should have a larger presence in order to stay true to its mission. With the encouragement of the Board of Trustees, this was followed up with a Computing and Information Sciences retreat on August 18, led by Provost Jackie Huntoon, where more than 60 member of the Michigan Tech community came together for a day and got a lot of issues out on the table. There was an excellent keynote address by Michigan Tech alumnus and benefactor Dave House, really driving home the point that the world has changed and that Michigan Tech needs to be paying attention. The retreat was a success, I believe, for raising awareness and getting people to think about what we might do. Of course, there were as many ideas about that as there were people in the room.

This brings us to present. Provost Huntoon has formed a Computing and Information Sciences (CIS) Working Group and asked me to lead it, and of course I jumped at the opportunity. The other members are: Min Song (CS), Jim Frendewey (SoT), Laura Brown (CS), Tim Havens (ECE/CS), Roger Kieckhafer (ECE), Myounghoon Jeon (CLS/CS), and Benjamin Ong (Math). Our charge is to use the time we have this year to develop recommendations designed to promote growth in size and quality of the degree programs and the University’s research portfolio in computing and information sciences, in the broadest sense. The recommendations are due to the Provost prior to the end of the 2017-2018 academic year. She will review those recommendations and use them to provide guidance to the future University president and the University’s Board of Trustees. Throughout the year we will periodically engage with a broad-based Advisory Group to share ideas and receive feedback. We have already gotten started, but now that some of the early-semester tasks are behind us I hope to really gather some momentum.

Most likely the topic of computing and information sciences at Michigan Tech will be the theme for this column, for much of the rest of this semester. The reader might wonder why I led off this story with a description of the change of seasons in the Upper Peninsula, which on the surface sounds a little ominous. You have to understand: I love the winters here at Michigan Tech. I am energized by the snow and all the winter sports that come with it. For me, this is not a time of hibernation, it’s a time of joy and rejuvenation, even during the shortest days and the darkest nights. I hope to bring some of that enthusiasm to the important task before us, and if we make any progress you will read about it right here.

Last weekend Michigan Tech was privileged to host Silicon Valley entrepreneur and writer Martin Ford, author of the NY Times bestseller Rise of the Robots, which is all about the disruptive changes in the recent past and future in the areas of robotics, control, and automation, and the implications for our society and our economy. I was able to join Mr. Ford for a couple of different question-and-answer sessions with interested faculty, and to attend his presentation at the Rozsa Center which was open to the general public. I found the entire day to be stimulating and compelling, and I was very happy about the fact that Career Services and the Rozsa Center were able to work together and pull this off. The evening presentation was very well attended and included a lot of students. I was impressed that so many people were willing to give up their Saturday to hear a PowerPoint presentation about automation – but it really was that good.

Ford’s basic premise was twofold. First, although there have always been concerns raised about changes in employment and the economy due to technological advances, going all the way back to the Luddite movement in 1811, this time things are different due to the nature of the technological advances themselves, primarily in the area of artificial intelligence and deep learning. Second, there has been a marked shift in the relationship between worker productivity and worker compensation, that has led to increased inequality and that will probably continue into the foreseeable future.

The argument that “this time it’s different” centers around the sudden relevance of artificial intelligence and machine learning in engineered systems. Artificial intelligence has been around a long time, and for most of that time I have thought of it as the technology of the future – always has been, always will be. Now, in the past 5-10 years or so, it is becoming the technology of the present. This is due to a couple of factors. One is, the raw computing horsepower needed to carry out artificial intelligence calculations is starting to become a reality, due to the inexorable march of Moore’s Law (which says that, essentially, computing power per unit area on integrated circuits doubles every 1.5 to 2 years.) The second is the algorithms themselves, which have been steadily improving in academic research labs for many years, and which are now getting a turbo boost of innovation in industrial research labs like those of Google and Facebook, who recognize the importance to their bottom line. As evidence that we have turned a corner in artificial intelligence, Ford and many others love to point to the IBM Watson 2011 victory in an exhibition match of the TV game show “Jeopardy” over two human champions Ken Jennings and Brad Rutter. More recently, a program called AlphaGo was developed by Google DeepMind in London to play the enormously complex game of Go, and in May of this year it defeated the No. 1 player in the world in a 3-game match in Wuzhen. What is particularly interesting about AlphaGo is that it is not based on a set of rules or heuristics, but rather it simply (perhaps not so simply) trained itself to play the game through a process of trial and error using the techniques of machine learning. This whole field of “deep learning”, based on artificial neural networks made bigger and better as a result of Moore’s Law, is taking Silicon Valley by storm and has really transformed the economic focus there from electronics to software.

[Aside: I have always maintained that the IBM Watson Jeopardy match was not a fair fight. To make it fair, the entire computing platform and its database would have to fit into a box no bigger than 1500 cubic centimeters, consume no more than 20W of power, and be silent when others are speaking. Watson was a very large computer consisting of multiple servers in a separate room with a very loud air conditioning system, and it had access to huge databases of information. Human players are not allowed to “phone a friend” during the match. The counterargument, I suppose, is that the human players had the advantage of 30+ years of training.]

The starting point for Ford’s argument on the economic disruption of automation is in the relationship between worker productivity and worker compensation. In what is considered by the many the “golden age” of American manufacturing, post-WWII, advances in tools and technology allowed workers to become more and more productive, according to a metric of goods and services produced per unit time. As a result, workers became more and more valuable and thus wages went up in lock-step with productivity. Sometime in the mid-1970s, however, this coupling was broken. Worker productivity continued to go up and up, but wages became flat. Ford often made the statement that, adjusted for inflation, American workers have not received a raise in 40 years. He attributes this to a shift from a situation where tools helped human workers be more productive, to a situation in which tools can simply replace the human workers. The situation continues to this day, and the outlook is for it to continue even more rapidly, leading to greater levels of income and wealth inequality and hence social disruption.

Asked whether he was an optimist or a pessimist, Ford responded that he was a pessimist in the short term, based on the realities on the ground, but that he is still an optimist in the long term when he thinks about human resilience and ingenuity. There are some serious problems we are going to have to come to grips with, but if we can work together to recognize and solve those problems, and maybe even get out in front of them, then there is still hope. He is realistic, but not all doom and gloom. I did find his approach different, and more down to earth, from that of other futurist authors I have read lately, some of whom are wildly optimistic about the future of the human race and its relationship to the machines we are creating.

I found myself nodding in agreement with most of the Ford’s points, and had my own takeaway messages. The first is, and I realize this may sound a bit selfish, this is a fantastic time to be an electrical or computer engineer or computer scientist, about to be entering those fields. The technologies of robotics, control, and automation are advancing rapidly, and the advances are not about to stop. We are the ones who are creating this technology, and thus we are the ones who are going to be in demand in the next few decades. Ford himself, knowing that he was at a technological university, made a couple of offhand remarks to the effect that “you guys are going to be OK for a while.” Those who are losing out socially and economically could say that we are part of the problem, and they may very well have a point, although I think as well-educated problem solvers there is every reason to think we can be part of the solution as well. But, setting that aside for a moment, from the individual point of view I would have to say that I cannot imagine a better career to be considering right now than something in the intersection of EE, CpE, and CS.

As evidence of that I would point to our very own Career Fair, which was held this week. Over 340 companies were on campus recruiting Michigan Tech students for co-ops, internships, and full-time. My friends over in Career Services tell me that everybody – everybody – is looking for more electrical engineers and computer engineers. We cannot fill the demand right now of all the companies looking to hire our students. This story is reflected also in national starting salary data. According to the Spring 2017 report of the National Association of Colleges and Employers (NACE) which covers hiring of the Class of 2016, the top starting salaries by major in the nation, for groups with sample sizes of 500 or more, were:

Computer Science $78,199
Computer Engineering $74,439
Electrical Engineering $70,950

In the interest of full disclosure, Petroleum Engineering and Operations Research were higher, with sample sizes of 184 and 64 respectively. Petroleum Engineering used to be much higher, like over $100,000, but that has come way down and is now comparable to Computer Science.

These salary numbers are echoed locally. According to our Career Services 2016 Annual Report, Michigan Tech electrical and computer engineers (which were lumped together) had a 99% placement rate and an average starting salary of $65,951, which was highest among majors in the College of Engineering. ECE was second only to Computer Science, which did very well with an average starting salary of $78,333. The ECE figure is lower than the national average, but it is worth pointing out that many of our graduates take positions in the upper Midwest which has a lower cost of living than California. Our starting salaries are very close to what is reported in the NACE survey for the Great Lakes Region: EE $65,815 and CpE $67,610. Our Career Services numbers are self-reported and must be taken with a grain of salt; nevertheless there is no question in my mind that our graduates are doing very well. I never hear complaints otherwise.

A second point I want to make that was sparked by Martin Ford’s presentation, although tangential to his primary message, has to do with the ascendancy of the overall field of computing relative to engineering. He said it right out of the gate, that all the action in Silicon Valley right now is in artificial intelligence and deep learning. Silicon Valley got its name and its reputation from the design and manufacture of integrated circuits, but that is now taking a back seat to software engineering. The four U.S. corporations with the largest market cap right now are Apple ($791B), Google/Alphabet ($662B), Facebook ($490B) and Amazon ($459B). Apple still manufactures products, and Amazon manages a massive product distribution system, but even so the backbone and the core competency of these companies is essentially software. There are areas where software engineering intersects traditional engineering, to be sure, and the most visible example of that right now is in autonomous vehicles. The reason that Google can get into this game in the first place is that they do not have to design the power train. The value added by taking a traditional vehicle and making it autonomous comes from a suite of sensors, a trunk full of computing hardware, and all the cognitive data processing and artificial intelligence algorithms that end up controlling the accelerator, the brakes, and the steering. I predict that over the next 10-20 years we are going to see a lot more of these systems where the technological advances are primarily on the computational side, not on the physical side. I also believe that we need to be doing more to prepare our engineering students for a world that will be dominated by computing and software, and I will have much more to say about that in future columns.

Clearly my two take-away messages above were not really what Martin Ford came to talk to us about. In the end he advocated for a couple of things. One was more education in the social and economic impact of robotics and automation, which is certainly something I support and which would make all the sense in the world as part of our general education program. The second was starting a conversation around the idea of a guaranteed universal income. I think he is an proponent for this idea, but he recognizes the enormous political challenges and was content on this trip just to get people to start thinking about it. So, I am starting to think about it. I’m not ready to jump up and down arguing on either side, but am willing to learn more and have the conversation.

Fall is coming slowly to the Keweenaw this year. It’s been a wet summer and fall, so the colors should be pretty good as long as we can get a good cold snap to bring them out. Not seeing that in the forecast yet. Have a great weekend everyone!

This weekend Michigan Tech welcomes a special guest to campus. Martin Ford, Silicon Valley entrepreneur and author of the bestseller Rise of the Robots, will be here tomorrow to spend a day with faculty and students, and to give a presentation that is free and open to the general public. That’s Saturday, September 23, at 7:30pm, in the Rozsa Center for the Performing Arts, for those that are nearby and interested. I plan to spend a fair amount of time with Mr. Ford, both socially and as part of his schedule of speaking events, and am looking forward to that. Since I see robotics, control, and automation as a important strategic growth area for the ECE Department, I thought this would be a golden opportunity to share some thoughts on the topic. It also makes sense to put those thoughts together after this weekend’s activities, not before. Until then, Happy Autumnal Equinox and have a great weekend!

Today is the last day of our first week of the fall semester, and students are already getting their first break from classes. Later today is K-Day (short for Keweenaw Day), an outdoor event with food, music, and lots of practical information about activities at Michigan Tech, held at McLain State Park, on the shores of Lake Superior about 10 miles from campus.

The weather for K-Day promises to be absolutely beautiful, which is in contrast to the cool, rainy weather that we have seen recently. We joke a lot about our “reliable crummy weather” but in truth things here are pretty benign, and I even include our winter snowfall in that statement. We have nothing that compares with the devastation caused by Hurricane Harvey in SE Texas, or Hurricane Irma which has wreaked havoc in the Caribbean and is bearing straight down on Florida. I’ll take the rain any day over the drought in the western U.S. which has led to practically apocalyptic wildfires that are barely making the news. My daughter, a college student in Bellingham, Washington, came home to visit this week, and as she got off the plane she remarked that this is the first time she has been able to breathe clean air in days. So, we count our blessings, and of course our hearts go out to all our fellow citizens whose lives are being negatively impacted by these weather events.

This weekend I hit a personal milestone – my 60th birthday is this Sunday, September 10. It is not really an accomplishment of any sort, other than just having lived this long, but I plan to celebrate nonetheless. I have never been shy about birthdays, and am not one of those people that tries to ignore the fact that I am a year older. Party on, that’s what I say!

I understand that a person’s 60th birthday is a major life event in Chinese culture; it has something to do with the 12 years of the Chinese zodiac and the belief that going through that cycle five times represents the completion of an even larger cycle (I defer to my Chinese friends and colleagues for a better explanation.) When my PhD advisor, Prof. Bede Liu of Princeton University, had his 60th birthday, a bunch of his former PhD students organized a big surprise party and people flew in from all over the country to celebrate with him. We even held a mock PhD oral qualifying exam for him, with former student Dave Munson (later Dean of Engineering at the University of Michigan, now president of Rochester Institute of Technology) presiding. That was 23 years ago, and Bede is still going strong. Coming up on this weekend brings back fond memories of Bede and how I still reach out to for him for advice on major life decisions – like a marriage proposal in 1994, and coming to Michigan Tech in 2008.

As is often the case with milestones in life, this is a good time to look forward with optimism and resolve. This academic year I am starting my 10th year at Michigan Tech, and my 4th 3-year term as department chair in the ECE Department. I feel reasonably confident that I still have something to offer, and am eager to do what I can to help move the department and the university in the right direction. This is not to say there is no room for improvement! Most of what I have learned about university administration I have learned on the job, and I am still learning. I have gotten a lot of very good advice over the years from colleagues and mentors, notably the namesake on my professorship Dave House. Dave is fond of saying “Experience is something you get right after you need it” and I have seen that play out many times.

I have also seen the importance of clear, concise communication in my position, and so I greatly appreciate the keynote presentation we had yesterday evening for all the first-year engineering students at Michigan Tech, given by Libby Titus, a Michigan Tech Environmental Engineering alumna and a technical communications expert at Novo Nordisk. Her topic was the importance of communications skills, particular writing skills, for professional engineers. I thought all of her points and her advice were spot-on. One point that she made is that the technical skills acquired in engineering school, as difficult and challenging as they seem to students at the time, are in retrospect easy compared to all the interpersonal skills that are required in the workplace. Communication skills are particularly important, and people who are effective in communication are the ones who will reach a large audience with their brilliant technical ideas. “Engineering and science are group activities” was a phrase she repeated a few times. I especially appreciated the point she made about the importance of using correct grammar in all forms of written communication. Readers of my “Rants from the Grammar Maven” column from earlier this summer can imagine me nodding in violent agreement during that part of the talk.

As much as I agree with what was said at the talk yesterday, I will counter with one point. We have a lifetime to acquire interpersonal, management, and leadership skills as we mature, but the best time to learn math, science, and engineering is when we are young. So to all our engineering students in attendance yesterday, I would say that our speaker was 100% correct in everything she said, but don’t let that stop you from getting your geek on while you are here at Michigan Tech. This is the place to become the technical expert you want to be, or at least to get started in that direction. Yes, you need to be a good communicator, but you have to have something to say, and the best way to do that is become a great engineer first. This is the old “build your house on rock, not on sand” argument that I have used before. Our educational programs in engineering are set up to help you succeed as technical experts, and all the feedback we get from alumni and industry partners tells us that our approach based on strong fundamentals works. In other words, enjoy K-Day, but be ready to hit the books next Monday!
