Mathematical Sciences Department Students Taking Research to the Next Level

The Mathematical Sciences (MS) Department proudly announces that Aili Toyli and Sean Phelan have been selected for the Undergraduate Research Internship Program (URIP)*. Toyli and Phelan will spend the academic year working on individual research projects under the guidance of a Michigan Tech faculty mentor.

Additionally, Sean Phelan was awarded a Summer Undergraduate Research Fellowship (SURF)**. Research is conducted over the summer semester.

Both SURF and URIP are high-caliber undergraduate research opportunities that create a unique collaboration with professors and hone a student’s skills to distinguish themselves. 

Phelan’s SURF project title is, “Discovering Genetic Markers for Alzheimer’s Disease Using Genome-Wide Association and Rare Variant Association for Risk Prediction.” He is a dual major in Statistics and Mathematics–Business Analytics, under the advisory of Weihua Zhou—Applied Computing. We conducted an email exchange to find out more about Sean.

MS: What do you hope to do with your degree?

SP: “Work as a data scientist where I draw insights from large company data sets. I am interested in the operations and supply chain side of business where I can optimize the flow of resources.”

MS:  What piqued your interest in doing research?

SP: “I want to apply my statistical knowledge from MTU to real-world data and explore the world of deep learning. Research at the MTU bioinformatics lab is a perfect fit, where I learn about medical deep-learning models and develop statistical risk scores. My research also draws from an elective science course I took, Intro to Biotechnology with Dr. Busov.”

MS:  What do you enjoy most about the research you do?

PS: “Learning about new measures and models that I can apply in the future and keeping on top of cutting-edge machine learning methods are important for a budding data scientist.”

MS: What do you like to do outside of school?

PS: “I like to camp and backpack while exploring the outdoors. I also mountain bike and snowboard depending on the season.”

MS:  Why did you choose to study here at Michigan Tech?

SP: “I like the UP, I received a solid scholarship, and the math program is great.”

MS:  What do you like the most about Michigan Tech?

SP: “It’s a double-edged sword, but I like being in the middle of nowhere—so much outdoors and the air is so fresh. Also, the small-town energy here is very safe and friendly, which is much nicer than a large city like New York.”

Toyli is pursuing a B.S. in Statistics—under the advisory of Qiuying Sha— that she anticipates will open the door to a graduate degree in biostatistics, and a career as a statistical consultant for medical research. She has always been interested in both medical sciences and statistics, and knew she wanted to be in research. We asked Aili a bit about herself.

MS: What piqued your interest in research?

AT: “I attended the undergraduate research forum last fall and reached out to Dr. Zhou because I was intrigued by his work.”

MS: What do you enjoy most about research?

AT: “I enjoy applying what I’ve learned in class to real-world problems. I’m excited to contribute to research that could lead to improvements in medical treatments.”

MS: What have you learned most about yourself by doing research?

Ong Closes Contract from Lawrence Livermore National Laboratory

Benjamin Ong
Associate Professor Benjamin Ong

Benjamin Ong is the principal investigator (PI) on a project that has received a $45,000 research and development contract from the Lawrence Livermore National Laboratory, entitled “Systematic Approaches to Construct Coarse-Grid Operators for Multigrid Reduction in Time.”

Multigrid Reduction in Time (MGRIT) [2] uses multigrid reduction techniques to enable temporal parallelism for solving initial value problems. It is known that the convergence rate of MGRIT [3] depends in part on the choice of time-stepping operators on the fine- and coarse-grid, which we call the fine-grid operator and coarse-grid operator respectively. An “ideal” coarse-grid operator is the fine-grid operator applied to approximate the solution on the coarse time interval.

In practice, the ideal coarse-grid operator is never used as the computational cost destroys any parallel speed-up that could be obtained using MGRIT. Instead, a common choice for a coarse-grid operator is a simple re-discretization of the fine-grid operator, i.e., if a single-step method is used on the fine-grid with time-step size h, then the same single-step method is used on the coarse-grid with time-step size m h, where m is a specified coarsening factor.

Numerical simulations are increasingly important in the study of complex systems in engineering, life sciences, medicine, chemistry, physics, and even non-traditional fields such as social sciences. Dr. Ong is working to solve these large-scale evolution problems on modern supercomputing architectures by using a hierarchy of space-time grids to accelerate the solution on the finest time grid.

References

Time permitting, Dr. Ong will explore the connection between the proposed sequences of generated coarse-grid operators to those recently proposed by Vargas et al. [4].

Math’s McFall Makes Deans’ Teaching Showcase Finals

Patrick McFall
When he’s not in the classroom in Fisher, you can find McFall canoeing on Portage Lake

College of Sciences and Arts Dean Ravindra Pandey has selected Patrick McFall as this week’s featured instructor in the Deans’ Teaching Showcase.

McFall, assistant teaching professor in the department of mathematical sciences, will be recognized at an end-of-term event with other showcase members. Recognition qualifies him as a candidate for the CTL Instructional Award Series.

McFall served as the Director of the Math Learning Center from 2020-2023. He co-directed the center in 2023. McFall teaches many large sections of fundamental math courses for the department, going back to spring 2021. He’s appeared in the top 10% of Michigan Tech instructors based on the “Average of 7 Dimensions” for student evaluation scores in three different semesters.

McFall’s Teaching Experience Helps Reduce DFW Rate

In the spring of 2023, McFall took on the coordinator role for MA 1160/1161 Calculus 1. He co-developed the department’s proposal to address the DFW rate for this class. McFall was instrumental in implementing the project. He piloted weekly algebra reviews, and developed pre-class videos and quizzes for a blended learning structure. McFall provided handouts for all instructors to increase student engagement. McFall met weekly with the instructors to ensure consistency in instruction. As a result, the Spring 2023 DFW rate for MA 1160/1161 showed a significant decrease from previous spring semesters. The rate for Spring 2023 declined 25-30 percentage points lower than Spring 2022 and Spring 2021. McFall’s work continued this fall, with similar results.

McFall’s Teaching Garners Praise in the College

Jiguang Sun, Chair of the Mathematical Sciences department, praised McFall. “He is enthusiastic about teaching and promotes a positive and engaging environment in the classroom. Dr. McFall cares for his students, and provides motivation for learning.”

Maria Bergstrom, Associate Dean for Undergraduate Education in the College of Sciences and Arts highlighted the significance of McFall’s contributions as an outstanding instructor. “Patrick McFall’s work to reduce DFW rates in Calculus I through innovations in pedagogy and curriculum has had a tremendous impact,” she said. “The impact is not just in his department but also for undergraduate education as a whole at Michigan Tech. A solid understanding of calculus is fundamental to most of the science and engineering programs on campus. And thus student success efforts in these key courses have a ripple effect across campus. We are pleased to showcase his instructional achievements.”

Copper Country Scholars Funded by Jerry Davison ‘66 and Wife Judy

Jerry and Judy Davison
Jerry and Judy Davison

Kids across the United States dream and aspire for things bigger than them, whether that’s wanting to be an astronaut, a lawyer, a cowboy, etc… It’s no different in the small towns of Michigan’s Upper Peninsula; where, thanks to the influence of Tech, many dream of being computer scientists, engineers, and scientists. Michigan Tech alumnus Jerry Davison ‘66 and his wife Judy, just made it easier for those dreams to come true by establishing the Copper Country Scholars Endowed Scholarship Fund. The scholarship is open to hard-working students in science, engineering, math, and computer science with financial needs who have graduated from Copper Country schools and are currently attending Michigan Tech with a minimum 2.75 GPA.

Growing up in the Copper Country is rigorous and difficult. Rugged terrain, Superior’s gales, bone-chilling cold, plentiful snow, and isolation- conditions that prepare students for the rigor and difficulty of Michigan Tech coursework. Jerry (and Judy, a Michigan graduate) knows it well as a Yooper from Calumet, just 13 miles from campus.

Jerry’s parents instilled their hard-working, blue-collar values from an early age. He saw those values in action in the community around him. Additionally, he also saw how the community stayed together and supported each other. His family was connected to Tech. Like his sister, he worked in the business office at Michigan Tech. Their father worked in the Maintenance Department. Jerry earned $1.25 per hour to pay his college tuition, toiling hard and persevering until his graduation with a B.S. in Mathematics.

Jerry had always been drawn to the field of computers. However, during his time at Tech, there was no Computer Science degree program available. “I started off my career interviewing with communications, steel, and aerospace companies and The National Security Agency, but my career took me all over. I worked for many companies over the course of my career, including communications laboratories, a national laboratory, investment bank, insurance companies, hospital system; you name it. I was always hoping for a challenging new opportunity, never settling for the mundane,” said Davison.

Jerry’s values of hard work and determination helped him forge his own path; values he learned from his family and community. He recognizes the power of community members coming together to support each other. It is this recognition that drove him to establish the Copper Country Scholars Endowed Scholarship Fund. Jerry is hoping to give others like him the chance to forge their own path forward, achieve success, and give back to the community.

Jerry wants to emphasize that this scholarship is open for donations and remains nameless, keeping with the community’s spirit of coming together for a shared goal, rather than recognition or glamor. “I want this scholarship to be open to donations to make sure that we give back to those who come after us,” said Davison.

The Davisons’ contribution to Michigan Tech students is appreciated and has not gone unnoticed. “I am so grateful for Jerry and Judy’s generosity, which will allow more of our own Copper Country students to afford the world-class STEM education that Michigan Tech provides, and hopefully inspire many more alumni to contribute to this scholarship,” said David Hemmer, dean of the College of Sciences and Arts.

If you would like to contribute to the Copper Country Scholars Endowed Scholarship Fund or inquire about other opportunities, please contact Karin Van Dyke, Michigan Tech University, Director of Advancement, 1400 Townsend Drive, Houghton, MI 49931. Email: kvandyke@mtu.edu. Phone: 906-487-2464

A Super Sweet Pi Day Celebration

Pi Day was celebrated in the Department of Mathematical Sciences on Tuesday, March 14 (3/14) at 1:59pm.

Are you starting to see a slight pattern here – 3.14159? Pi Day celebrations were held throughout the world on March 14 and we thought it would be fun to join in on the festivities.

As you probably already know, the Greek letter “Pi” is a mathematical symbol used to represent a constant. One of the most well known mathematical constants is the ratio of a circle’s circumference to its diameter. So, in keeping with the mathematical related theme, pie was served!

Several members of the faculty, staff and student body in the math department joined together on Pi Day to chow down on their favorite variety of that sweet, circular treat – PIE. As a matter of fact, a total of 12.14159 different selections of pie adorned a conference table in the math lounge for sampling.

Additionally, undergrad math majors were invited to participate in a very irrational game of Pi Bee. Here, students tested their memory by recording as many digits of pi they could remember – unassisted.

Many entries were submitted, but there could be only one winner. Eli DeWitt (General Mathematics major) provided a heaping total of 43 correct and consecutive digits. His sweet reward for such an outstanding memory was a gift card to the Campus Book Store.

We look forward to the infinite possibilities for future celebrations. Check out our Facebook page https://www.facebook.com/profile.php?id=100086619613325 to see some of the other interesting events taking place in the department.

Xiaoqing Gao
Michigan Tech PhD student Xiaoqing Gao

We are honored in the Mathematical Sciences Department to have one of our PhD students Xiaoqing Gao compete in the 2022 3-Minute Thesis Competition. This is such awe-inspiring experience and accomplishment for our students.

What is 3MT?

The 3MT is an important international competition that aims at celebrating research conducted by doctoral and masters students. According to the University of Queensland, founder of the event, the 3MT “cultivates students’ academic, presentation, and research communication skills”.

Participants have three minutes and a single static slide to effectively explain their research in a language that is appropriate to a non-specialist audience.

Xiaoqing Gao Awarded 1st Place

I am a PhD student majoring in Biostatistics under the supervision of Dr. Kui Zhang. The current research is focused on ‘Using LSTM machine learning method to do HLA imputation.’

Presented research is about using viral genomic sequences to predict human-infecting viruses.

Abstract: Covid-19 pandemic results in crucial modification in our lives. To prevent outburst of a new virus, it is essential to understand if a virus is capable of infecting humans. As the technology of genomic sequence detection is getting mature, it is efficient and consequential if we could analyze the virus characteristics and perform the prediction based on the given sequences. The goal of her paper is to predict if a virus is a zoonotic virus and evaluate the extent of the zoonotic virus.

Also, I would like to appreciate my advisor Dr. Kui Zhang for the guidance of this paper and my career. It is a great pleasure to study in this department.

-Xiaoqing Gao

Xiaoqing was awarded First Place in the competition. Such an amazing experience and so very impressive to do this in just 3-minutes.

If you see Xiaoqing please join me in congratulating on such a huge accomplishment! We are so proud of you.
