Highlights

We had an outstanding Putnam Team this year, which included Yerasyl Abdimash, Andrew Caleshu, Dashiell Elliott, Taran Kaylor, Lily Kropp, Paul Lesyk, Yutaro Matsuyama, Adam Mullaney, Uri Netzer, Roy Sianez, Kendall Snyder, and Arlan Zbarsky. Please join me in congratulating this year's Putnam team for getting a team rank of 85 (out of 487) in the 86th Putnam Competition that took place in December!

The William Lowell Putnam Mathematical Competition is the most prestigious mathematics competition for undergraduates in the US and Canada. This exam has taken place every year since 1938 and previous winners have gone on to win the Fields Medal (e.g. John Milnor, David Mumford, and Daniel Quillen). These tests are extremely challenging-- the median score of the most recent exam was a 2. On Saturday December 6th, this talented WPI Putnam team completed two sessions (A and B), each lasting 3 hours. WPI's top scorers this year were Taran Kaylor with a score of 23, Yutaro Matsuyama with a score of 20, Dashiell Elliot with a score of 11, Adam Mullaney with a score of 10, and Arlan Zbarsky with a score of 10.

A special thank you to Prof. Guanying Peng for his time and efforts working with this talented group in B-term Denksport (MA 1801). We will start training for the 87th Putnam Competition again next fall. Please consider joining the team!

Kendall Snyder, a graduating math major, won a Pi Mu Epsilon Student Speaker Award. It was presented at Pi Mu Epsilon (PME)'s annual meeting on January 6, 2026. Snyder is one of sixteen undergraduates who won the award this year. PME is an academic society that promotes mathematics and, particularly, student engagement with the subject.

In her own words, Snyder describes her talk that won the award and the experience of attending the conference:

"The presentation was titled 'Exploring the Game of Cycles,' and the talk discussed the background/origin of the game, some established winning strategies and general patterns in game play, and some new ideas regarding asymmetrical game boards. The game was invented in 2020 by Francis Su, who I had the privilege of meeting at my talk. Despite it being such a new topic, interesting results have come about over the past few years. Many winning strategies have been defined on specific game boards and some specific types of game boards, such as trees. Most of the established winning strategies for this game are defined on game boards with high degrees of symmetry, but when examining game boards with lower degrees of symmetry or asymmetrical boards, previously defined strategies can be utilized if the underlying graph of the game board exhibits symmetries. I came to this topic when exploring ideas for my MQP. It was proposed to me by Professor Brigitte Servatius, who has since advised me on this research and encouraged me to attend JMM as well as give this talk. Without her help, none of this would have been possible. The experience was phenomenal. I was able to reconnect with friends from BSM (Budapest Semesters in Mathematics), meet other students with similar interests, and learn about research in topics I have never thought to explore."

Congratulations, Kendall!

For 35 years, excluding the Covid-affected ones, the WPI Department of Mathematical Sciences has been hosting an annual competition for high school students across New England. This outreach initiative is intricately connected to the Master of Mathematics for Educators (MME) program and serves as an essential bridge to the local high school community.

The 35th Annual Math Meet competition was held on October 17, 2025.  It involved 175 students and their advisors for a total of 44 teams (one team for each participating high school).

The top winners for this year were:

1st Place Team - Nashua High School South
2nd Place Team - TIE St. Mark's School and Worcester Academy
3rd Place Team - No award

We also congratulate the top 3 individual scorers: in first place, Pratham Mukewar from Nashua High School South; in second place, Vaibhav Rastogi from Bishop Brady High School, and in a tie for third place, Alex Ding from Worcester Academy and April Sun from Lynnfield High School.

The success of Math Meet owes much to the dedication of our department, graduate students, staff, and the Math Meet committee. A huge thank you to everyone that helped to make this event a great success!

Pictured above is the top-scoring team, Nashua High School South, from Nashua, NH. A big congratulations to the team members, Ameya Kharade, Pratham Mukewar, Samarth Sharma, and Hannah Thomas, and to their advisor and teacher, Kellie Gabriel!

Prof. Vadim Yakovlev, adjunct teaching professor of mathematical sciences, has received a new one-year award from the Oak Ridge National Laboratory (ORNL). The research, titled "Models and Machine-Learning Algorithms for Energy Efficient Carbon Fiber Production Using Microwave-Assisted Plasma," is sponsored by the Department of Energy in the framework of the "High Performance Computing for Manufacturing (HPC4Mfg)" Program and will involve participation of RTX Corporation (formerly Raytheon Technologies Corp.).

Due to its unique mechanical and physical properties, carbon fiber (CF) is an extremely valuable material for the aerospace and automotive industries. ORNL has demonstrated that carbonization, a key step in CF production, can be made much faster and more energy efficient when accompanied by microwave plasma processing. However, promising results have been demonstrated on small-scale equipment. This project will create an electromagnetic model of a microwave system in which plasma-driven carbonization is to be carried out, and its performance will be optimized using specialized machine-learning algorithms. The developed modeling and optimization approaches will then be implemented in ORNL's HPC environment. This will pave the way for CAD of efficient large-scale carbonization devices and potentially facilitate the development of microwave plasma technologies on an industrial scale.

Congratulations to Vadim!

Discovering disease-associated genes from whole genome sequencing datasets is challenging and current methods operate with low precision. Prof. Zheyang Wu, Professor of Mathematical Sciences and affiliated with the Bioinformatics & Computational Biology Program and the Data Science Program, was recently awarded a 3-year project from the National Science Foundation to develop new statistical tools to enhance the power and precision of discovering disease-associated genes. By integrating diverse sources of genomic information and improving how prior knowledge and statistical evidence are combined, the project aims to uncover subtle genetic signals that might otherwise be missed. It focuses on two core challenges: (1) designing more effective weighting strategies for incorporating prior information when combining statistical significances, and (2) developing new methods to integrate discrete statistics within a general hypothesis testing framework. The project will implement and apply these approaches to whole genome sequencing data analysis. 

Congratulations to Zheyang!

Prof. Christopher Larsen, professor of mathematical sciences, has received a grant from the National Science Foundation (NSF) which supports his research on developing and analyzing mathematical models for material and structural failure. The project, titled "New variational methods for fracture evolution," is sponsored by the Division of Mathematics within the NSF.

For a large range of applications, from civil infrastructure to national defense, predicting the failure of materials and structures is critical. Our ability to predict failure depends on mathematical and computational models, and we need both to be as rigorous and physically justified as possible. Over the last 25 years, there have been significant mathematical advances in this area, which have directly improved computational models, particularly for fracture. However, these advances still have significant limitations - they are mostly restricted to models without applied forces, and existing mathematical models can entangle fracture nucleation and propagation in an unphysical way. Larsen recently formulated a mathematical model for fracture that isolates propagation and is compatible with all applied forces. The first goal of this project is to show existence of evolutions satisfying this principle. Another goal is to formulate models and show existence for evolutions satisfying both this principle and physical criteria for nucleation. Larsen also develops and studies improved computational models based on these mathematical results. The project includes training Ph.D. students.

Prof. Mayer Humi, professor of mathematical sciences, recently published a paper in the Journal of Mathematical Physics titled “Laplace conjecture about the formation of the solar system.” In the paper, Humi introduces a mathematical model based on solid physical laws that offers a support for the 1796 Laplace conjecture that described the sun as a cloud of gas having a very large radius that contracted inwards as it cooled and cast off a family of gas rings from which the planetary system later condensed.

Congratulations to Mayer!
