Mental models, constructing knowledge, programming analogies.

Briana Bettin’s research interests are many. They include user experience, human factors, human-computer interactions, mental models, information representation, rural digital literacy, education, engagement, retention, and digital anthropology. Her Ph.D. dissertation aims to better understand how novice programmers approach learning programming, and how their construction of programming ideas might be better facilitated.

“I delve into mental models research and explore theories for how students might construct knowledge,” she explains. “Specifically, the major studies in my dissertation explore how prior applicable knowledge might allow for transfer to programming concepts, which can feel very novel to students who have never programmed before.”

Bettin is also exploring methods for designing programming analogies, testing their application in the classroom, and observing how their use may impact student understanding of specific topics. “I take a very user experience-oriented approach, and work to apply methods and ideas from user-experience research in the CS classroom space,” she says.

Creative energy, insight, and humanity.

With Computer Science department faculty members Associate Professor Charles Wallace and Assistant Professor Leo Ureel, Bettin has worked on projects studying how novice programmers communicate. She and Ureel also worked on several ideas in the introductory CS classrooms, including exploring pair programming obstacles in the classroom and in research.

“I got to know Dr. Wallace during my Ph.D., and I love getting his perspective on research ideas,” Bettin says. “He has so many interesting ideas, and he’s so fun to talk to!”

“Briana brings loads of creative energy, insight, and humanity to everything she does,” says Wallace. “We are very fortunate to have her with us.”

Passionate about Computing Education.

Other research collaborators include Lecturer Nathan Manser, Geological and Mining Engineering and Sciences, and Senior Lecturer Michelle Jarvie-Eggart, Engineering Fundamentals, College of Engineering, with whom Bettin has explored topics in technology acceptance across engineering and computer science.

“Briana has been an enthusiastic addition to our research group,” Jarvie-Eggart says, who is working with Steelman and Wallace on improving engineering students’ acceptance of programming. “She really is amazing!”

Jarvie-Eggart sat in on Bettin’s Intro to Programming class in fall 2019, and noted that Bettin’s. approach of teaching algorithmic thinking and logic—before students begin programming—helps make programming more accessible to all.

“It builds foundational knowledge from the ground up,” she says. “Our research team is very excited about using her progressive CS education approaches to teach engineers programming.”

Stefka Hristova, in Michigan Tech Humanities, has always been supportive, helping me cultivate an interdisciplinary research vision and voice,” Bettin says. “Dr. Robert Pastel has also been so valuable in helping me approach my research with strong design. He has given me a lot of insight and I am so appreciative!”

“Briana is passionate about Computing Education, and she is invested in infusing equity and diversity into the STEM field,” Hristova says.


In Part III of this article, to be published soon, Briana Bettin talks about peer mentors and friends … and they say a few words, too.

Sangyoon Han to Present Chemistry Seminar this Friday, Nov. 13, at 3 pm

A Chemistry Seminar will be presented Friday, September 13, 2020, at 3:00 p.m., via online meeting.

Dr. Sangyoon Han will present his lecture, “Toward Discovery of the Initial Stiffness-Sensing Mechanism by Adherent Cells.” Han is an Assistant Professor in Biomedical Engineering, an Affiliate Assistant Professor in Mechanical Engineering-Engineering Mechanics, and advisor for the Korean Student Association. Han is a member of the ICC’s Center for Data Science.

Lecture Abstract

The stiffness of the extracellular matrix (ECM) determines nearly every aspect of cellular/tissue development and contributes to metastasis of cancer. Adherent cells’ stiffness-sensing of the ECM triggers intracellular signaling that can affect proliferation, differentiation, and migration of the cells. However, biomechanical and molecular mechanisms behind this stiffness sensing have been largely unclear. One critical early event during the stiff-sensing is believed to be a force transmission through integrin-based adhesions, changing the molecular conformation of the molecules comprising the adhesions that link the ECM to the cytoskeleton. To understand this force transmission, my lab develops experimental and computational techniques, which include soft-gel-based substrates, live-cell imaging, computer-vision-based analysis, and inverse mechanics, etc. In this talk, I will talk about how we use soft-gel to quantify the spatial distribution of mechanical force transmitted by a cell, how we use light microscopy and computer vision to analyze the focal adhesions, and how these techniques are related to stiffness sensing. In particular, I will show you new data where cells can transmit different levels of traction forces in response to varying stiffness, even when the activity of the major motor protein, myosin, is inhibited. At the end of the talk, potential molecules responsible for the differential transmission will be discussed. 

Researcher Bio

Sangyoon Han received his Ph.D. in Mechanical Engineering at the University of Washington (UW) in 2012 and did postdoctoral training with Dr. Gaudenz Danuser in the Department of Cell Biology at Harvard Medical School and the University of Texas Southwestern Medical Center for five years until 2017. Before the Ph.D., he received B.S and M.S. degree from Mechanical Engineering at Seoul National University, Seoul, Korea in 2002 and 2004.

He joined Michigan Tech, Biomedical Engineering from fall 2017, and started Mechanobiology Laboratory. His lab’s interests are in understanding the dynamic nature of force modulation occurring across cell adhesions and cytoskeleton that regulate cells’ environmental sensing. His lab develops a minimally-perturbing experimental approach and computational techniques, including soft-gel fabrication, nano-mechanical tools, live-cell microscopy, and image data modeling, to capture the coupling between force modulation and cellular molecular dynamics.

Accessible Computing Expert Dr. Richard Ladner to Present Keynote November 13

The ICC’s Center for Human-Centered Computing invites Michigan Tech faculty, staff, students, and alumni to a keynote lecture by leading accessible design expert and research scientist Dr. Richard E. Ladner on Friday, November 13, 2020, at 1:00 p.m., via online meeting.

His talk, “Accessible K-12 Computer Science Education,” is the final event of HCC’s Husky Research Celebration, a showcase of interdisciplinary HCC research through a series of virtual lab tours, virtual mini talks, and lectures presented in a 360-degree virtual space. More details here.

Ladner is a Professor Emeritus in the Paul G. Allen School of Computer Science and Engineering at the University of Washington, where he has been on the faculty since 1971.

His current research is in the area of accessible computing, a subarea of human-computer interaction (HCI). Much of his current research focuses on accessible educational technology.

Ladner is principal investigator of the NSF-funded AccessComputing Alliance, which works to increase participation of students with disabilities in computing fields. He is also a PI of the NSF-funded AccessCSforAll, which is focused on preparing teachers of blind, deaf, and learning disabled children to teach their students computer science.

Lecture Title: Accessible K-12 Computer Science Education

Lecture Abstract: For the past twelve years there has been rapid growth in the teaching of computer science in K-12 with a particular focus on broadening the participation of students from underrepresented groups in computing including students with disabilities. Popular tools such as Scratch, ScratchJr, and many other block-based programming environments have brought programming concepts to millions of children around the world. Code.org’s Hour of Code has hundreds of activities with almost half using block-based environments. New computer science curricula such as Exploring Computer Science and Computer Science Principles have been implemented using inaccessible tools. In the meantime the United States has about 8 million school children with recognized disabilities which is about 16% of the K-12 student population. It is generally not the case that these students are adequately served by the current K-12 computer science education or any of the block-based programming environments.

In particular, the approximately 30,000 blind and visually impaired children are left out because only a few educational tools are screen reader accessible. In this talk we address this problem by describing two programming environments that are accessible: the Quorum Language and Blocks4All. The Quorum Language, created by Andreas Stefik, is a text-based programming language whose syntax and semantics have been created to be as usable as possible using randomized controlled trials. The language is not at all intimidating to children. For younger children, Lauren Milne created Blocks4All a block-based programming environment that can be used by anyone including children who are blind or visually impaired. Blocks4All uses a touchscreen platform similar to ScratchJr and takes advantage of the fact the blind children already know how to use touchscreen devices using their built-in screen readers. The challenge for the future of K-12 computer science is to be more inclusive to all students regardless of race, ethnicity, gender, socioeconomic status, and disability status.

Junqiao Qiu to Present Lecture November 6

Assistant Professor Junqiao Qiu, Computer Science, will present his lecture, “Speculative Parallelization for FSM-centric Computations,” this Friday, Nov. 6, 2020, at 3:00 p.m., via online meeting.

Lecture Abstract

As a fundamental computation model, finite-state machine (FSM) has been used in a wide range of data-intensive applications, including malware detection, bioinformatics, semi-structured data analytics, natural language processing and even machine learning. However, FSM execution is known to be “embarrassingly sequential” due to the state dependences among transitions. Current studies find that speculation is a promising solution to address the inherent dependencies in FSM computations and thus enables scalable FSM parallelization.
This talk will firstly introduce the fundamental scalability bottleneck in the current FSM parallelization, and then an aggressive speculation, a generalized speculation model that allows a speculated state to be validated against the result from another speculation, is proposed to address the scalability limitations. Finally, this talk will discuss the possibility to enlarge the applicability of the proposed approach and go beyond the FSM-based computations.

Juneiao Qiu is a member of the Institute of Computing and Cybersystems’ (ICC) Center for Scalable Architectures and Systems (SAS).

Briana Bettin, Asst. Prof., Part I: Neopets, HTML, Early Success

Briana Bettin, Ph.D., Computer Science: New Degree, New Position

By Karen S. Johnson, Communications Director, College of Computing

Michigan Tech Ph.D. graduate Briana Bettin, Computer Science, is among six new faculty members the College of Computing welcomed this fall. Bettin is an assistant professor for the Department of Computer Science, and an affiliated assistant professor for the Cognitive and Learning Sciences department.

She is teaching courses including CS1121 Introduction to Programming in C/C++, and pursuing research and other projects with faculty and students.

In August 2020, Bettin successfully defended her dissertation, “The Stained Glass of Knowledge: On Understanding Novice Mental Models of Computing,” and was awarded her Ph.D. in Computer Science.

“I’m excited to begin my faculty journey at Michigan Tech and I look forward to helping our students continue to learn skills that will allow them to create the future,” Bettin says. “Michigan Tech has always been an amazing place for me—the opportunity to continue to give back to this place that has given me so much is something I’m very grateful for.”

Bettin says that she is excited about several interesting research projects already being planned, and she looks forward to helping the College advance its educational and research visibility and standing.

Bettin is a member researcher of the Institute of Computing and Cybersystems’ new Center for Computing Education, which promotes research and learning activities related to computing education.


Neopets, HTML, CSS. Here’s how Briana Bettin got everything started.

Video games caught Bettin’s interest at a young age and as she grew older, she became interested in online games like Neopets, which allows the user to develop a profile using HTML.

“So, I became excited to learn about HTML and CSS in order to express myself in those online spaces,” she says. “This also got me interested in graphic design, and both of these things combined got me hooked on the idea of creating expressive virtual spaces.”

Bettin earned her Bachelor of Science in Computer Science, with an Application Area in User Experience and Marketing, from Michigan Tech in spring 2014. Following, while working full time as a front-end web developer at a consulting firm, in summer 2016 she completed her master’s degree online. In fall 2016, Bettin began her Ph.D. studies.

The right fit.

“I wasn’t always sure if Computer Science was ‘right’ for someone like me,” Bettin reflects. “But my Ph.D. advisor, Dr. Linda Ott, would encourage me by reminding me of the vast opportunities in technology. And since I became aware of the interdisciplinary area of User Experience, my interest in programming has only grown!”

“Dr. Ott is absolutely amazing,” Bettin says of Professor Linda Ott, chair of the Department of Computer Science. “I am thankful for her, and I knew that having her as my adviser would be one of the best things I could hope for. Our working styles are very complementary, and she is a great motivator and supporter. Laura Brown and Nilufer Onder have also been great mentors, offering me wonderful advice and support whenever I talk to them.”

Bettin adds that Assistant Professor Leo Ureel, Computer Science, was “wonderful in helping me develop my research vision. We often bounce ideas, and he has supported my ideas and given me many opportunities to implement research ideas in the classroom. Our talks give me so much perspective and energy.”

Early teaching success, fellowships, and awards.

Bettin was a CS 1121 lab instructor from fall 2016 until fall 2019, when she became the instructor of record, teaching her first semesters as a lecturer in fall 2019 and spring 2020. That fall, she received outstanding “Average of 7 Dimensions” student evaluation scores, one of only 74 such accolades earned by faculty that semester.

But Bettin’s excellence was recognized long before, in fall 2017, when she received the Outstanding Graduate Teaching Assistant award from Michigan Tech’s Graduate Student Government.

Bettin was awarded the King-Chavez-Parks Future Faculty Fellowship from the State of Michigan in fall 2018. She received several doctoral consortium stipends from organizations including Institute for Clinical and Economic Review (ICER), the Frontiers in Education Doctoral Symposium (FIE), and the Computing Research Association’s Committee on the Status of Women in Computing Research (CRA-W).

A Google Scholar award made it possible for her to attend the 2017 Grace Hopper Celebration, which supports women in computing and organizations that view technology innovation as a strategic imperative. In fall 2019, Bettin was nominated for the prestigious MAGS Teaching Award.

Part II of this article will be published soon. In the second installment we’ll learn about Briana’s teaching and research, and the faculty and peer mentors who supported her as she completed her Ph.D.

Hongyu An: Curious About the World and Exploring the Unknown

by Karen S. Johnson, Communications Director, ICC

“A scientist should be a person who is always curious about nature and the world, and who tries to explore the unknown.” –Hongyu An, Assistant Professor, Electrical and Computer Engineering

Hongyu An, Assistant Professor, ECE

Exploring science and technology is always exciting for new Assistant Professor Hongyu An, Electrical and Computer Engineering. He says he is “very pleased to have the chance to mentor the next generation and share my knowledge and experience with undergraduate and graduate students.”

Several things drew Hongyu An to Michigan Tech, including his observation that as an institution Michigan Tech cares about its employees. “The excellent professors, smart students, and the supportive environment are the main reasons I joined Michigan Tech,” he says. “As a new faculty member, I am facing a lot of new challenges. There is great support in my department (ECE) and through the ICC.”

Hongyu is a member of two Institute of Computing and Cybersystems (ICC) research centers: Human-Centered Computing and Scalable Architectures and Systems. He also sees synergies with the Center for Cyber-Physical Systems.

“It is my great pleasure and honor to be a member of the ICC,” Hongyu says. “ I can collaborate with the experts in HCC for exploring the brain and artificial intelligence, and the professors in SAS for hardware and architecture designs. Moreover, the neuromorphic chips I am working on can potentially be applied to Cyber-Physical Systems.”

Hongyu’s primary research area is hardware design for AI and neuromorphic systems. He believes that Artificial Intelligence is probably one of the most challenging research topics in science, noting that recent work in deep learning and artificial neural networks is demonstrating great progress in approaching artificial intelligence. 

“But the traditional computers under von Neumann architecture cannot keep up with the development of neural networks and deep learning,” he cautions. “My research is addressing this challenge by using a new hardware design, from device to architecture levels.”

Hongyu’s teaching interests include VLSI, Circuits, and Electromagnetics. Desribing his teaching philosophy, he notes that making complicated things simple is more challenging than making simple things complicated, and that he strives for the former. This academic year, An is teaching EE 4271 VLSI Design and mentoring ECE master’s student, Sarvani Marthi Sarvani, whose project aims to design a silicon retina through CMOS and Memristors.

Hongyu and his research team are also investigating associative memory learning, a new learning method that aims to create a neuromorphic system that can learn from its surroundings directly. 

“Associative memory is a widespread self-learning method in biological livings, which enables the nervoussystem to remember the relationship between two concurrent events,” Hongyu explains. “Through this learning method, dogs can learn the sound of bells as a sign of food; people can remember a word representing an object.”

“The significance of rebuilding associative memory at a behavioral level not only reveals a way of designing a brain-like, self-learning neuromorphic system, it is also to explore a method of comprehending the learning mechanism of a nervous system,” he adds.

And finally, beyond his work as a professor and scientist Hongyu hopes that he is “a good husband to my wife, a good father to my sons, and a good son to my parents.”

Hongyu completed his Ph.D. in electrical engineering at Virginia Tech, his M.S. in electrical engineering at Missouri University of Science and Technology, and his B.S. in electrical engineering at Shenyang University of Technology.

Hatti and Team Win Startup Competition

by Electrical and Computer Engineering 

Nagesh Hatti (ECE) was the lead of a startup team that took first place in a virtual entrepreneurial startup event focusing on Education, held earlier this month. The Techstars StartUp weekend was hosted virtually from São Judas University in São Paulo, Brazil. 

Hatti and team pitched “Inter-Self” a mobile-based app that focuses on the emotional health of students, combined with their interaction with fellow students, during projects and assignments. 

Hatti said the objective of their idea is to provide a feedback mechanism so instructors are aware of the overall emotional health of students, and then use that as an input to their instruction. 

Techstars Startup Weekend, in partnership with Google for Startups, is a 54-hour event created for entrepreneurs of all kinds. “It was an intense but rewarding experience,” Hatti said. “There was a lot of support and encouragement to come up with new ideas and execute on them.” 

Hatti said that many of the mentors participating in Techstars startup weekend were successful entrepreneurs who started companies at similar events.

Sajjad Bigham Named Quarterfinalist in DOE Solar Desalination Prize Contest

Assistant Professor Sajjad Bigham, Mechanical Engineering-Engineering Mechanics, and his team have advanced to the second phase of the American-Made Challenges Solar Desalination Prize contest for his project, “Sorption-Based ZLD Technology.”

The contest is sponsored by the Solar Energy Technologies Office (SETO) at the U.S. Department of Energy (DOE).

Bigham is one of 19 quarterfinalists. Each receives a $50,000 cash prize.

Selected from among 162 applicants, the quarterfinalists now advance to the second, Teaming phase of the competition, for which each research team will develop and successfully validate an operational prototype of their solar-thermal desalination system.

Bigham is a heat transfer and energy systems specialist studying the scientific and engineering challenges at the intersection of thermal-fluid, material and energy sciences.

His Michigan Tech research lab, Energy-X, is focused on understanding the fundamental transport science of important energy carriers at micro, nano and molecular scales. He is a member of the Institute of Computing and Cybersystems’ Center for Cyber-Physical Systems.

Project Title: Sorption-Based ZLD Technology
Location: Houghton, MI
Project Summary: State-of-the-art zero liquid discharge (ZLD) technologies are currently bound with either intensive use of high-grade electrical energy such as mechanical vapor compressors or high capital cost with environmental concerns such as evaporation ponds. A team of researchers from Michigan Technological University, Oak Ridge National Laboratory, and the company Artic Solar proposes to address these issues by an innovative desiccant-based ZLD desalination system in which a multiple-effect distillation (MED) unit is uniquely embedded at the heart of an absorption-desorption system. The technology employs an absorption-based thermally-driven vapor compressor concept to pressurize the vaporized brine of the ZLD crystallizer unit from a low-pressure absorber to a high-pressure desorber module. This eliminates the need for energy-intensive electrically-driven mechanical vapor compressors currently employed in advanced brine crystallizers.

Timely updates about the American-Made Challenges Solar Desalination Prize are posted here.

The American-Made Challenges are a series of prize competitions that incentivize the nation’s entrepreneurs to strengthen American leadership in energy innovation and domestic manufacturing.

The Solar Desalination Prize is a multi-stage prize competition intended to accelerate the development of low-cost desalination systems that use solar-thermal power to produce clean drinking water from saltwater. It is intended to help achieve the goals of the Water Security Grand Challenge.

Each stage of the competition has increasing prize amounts, totaling millions of dollars.
