REU Site : Appalachian Mathematics and Physics Site

About the REU site

The Department of Mathematics and Physics at Marshall University is proud to host the REU Site: Appalachian Mathematics and Physics Site, an 8-week summer undergraduate research program that will run during Summer 2025. This program focuses on providing research opportunities in mathematics and physics to undergraduate students. Participants will receive a $5,600 stipend, paid housing in the campus dormitories, and a meal plan for the duration of the program.

Dates, eligibility, and deadlines

Dates of REU: 2 June 2025-25 July 2025
Who is eligible?: As per the NSF rules, only US Citizens or Permanent Residents without a bachelor's degree may participate.
Deadline to apply: 1 March 2025 and we will accept applications until all participants are selected

Location

Participants will be housed in a dormitory at Marshall University and be provided a campus meal plan. Housing and the meal plan is 100% paid for by the grant (i.e. it does not come out of the stipend!).

Marshall University was recognized as an R2 research institution in 2019. The faculty in the Department of Mathematics and Physics have a history of involvement in REUs, having hosted an NSA-funded REU in combinatorics in 2016 and being involved in a computational REU that ran in 2010--2014. Marshall University runs a Summer Undergraduate Research Experience (SURE) program and was recently awarded a different REU program in civil and environmental engineering.

All participants will have access to classroom space and computational hardware as-needed, and physics participants will have access to the necessary laboratory equipment to conduct their research. Participants will live in the dormitories of Marshall University and will be provided with a meal plan for the duration of the program. The dormitories are approximately a five minute walk from the two buildings in which research will occur. Marshall University has two libraries that can provide academic resources for participants, as well as additional collaboration spaces. The Memorial Student Center serves as a center point of campus with a welcoming foyer as well as nationally-franchised fast food and coffee shops.

Marshall University is located in Huntington, the second largest city in West Virginia. Its downtown area connects to the western edge of campus, and the city and its surrounding towns are host to numerous artistic and musical events each summer. Local transportation options exist for participants without a car. The Tri-State Transit Authority provides a bus service that connects the university to to local recreation, shopping locations, and restaurants in Huntington. Greyhound provides bus services to other nearby cities such as Charleston, WV and Ashland, KY. Huntington also hosts an Amtrak station with service to distant cities such as Chicago, Cincinnati, Philadelphia, and New York City.

West Virginia hosts numerous public recreation areas -- for example Beech Fork State park lies ten miles to the south of Huntington while the New River Gorge National Park, the United States' newest national park, lies near Fayetteville, WV, about a two hour drive from Huntington.

Projects

Binary neutron star mergers (advisor: Dr. Maria Babiuc-Hamilton)

One of the pivotal theoretical challenges faced by Multi-Messenger Astrophysics (MMA) is the accurate modeling of the effect of tides on the gravitational waves (GW) during binary neutron star (BNS) mergers and the mechanisms behind their electromagnetic counterparts, such as the emission of Fast Radio Burst (FRB) during the pre-merger and Gamma Ray Bursts (GRB) after the merger. We will address these three challenges while simultaneously nurturing the next generation of MMA researchers. This is achieved by engaging undergraduate students in the development of innovative techniques to demystify BNS mergers and their counterparts. By combining rigorous training with efforts in developing innovative approaches to the unresolved theoretical problems related to understanding BNS mergers, we ensure that future researchers are equipped to bridge the gap between observational data and theoretical predictions. Three well-defined projects can be explored:
  1. Project 1: Analytical modeling of the influence of tides on the gravitational wave signal during BNS mergers
  2. Project 2: The role of the magnetic field in the emission of Fast Radio Bursts during BNS mergers
  3. Project 3: Analytical modeling of Gamma Ray Bursts
Our analytical models are appropriate for undergraduates, requiring no knowledge of General Relativity, advanced mathematical methods or computer software. We will develop our software in Python, guided by a user-friendly Jupyter Notebook, or using Mathematica computational platform.
Recommended prerequisites: Differential equations, electricity and magnetism, mathematical analysis, experience with programming

Problems in algebraic graph theory (advisor: Dr. Sudipta Mallik)

This project involves graph theory and linear algebra. Many properties of a graph can be described by linear algebraic properties such as rank and eigenvalues of a matrix associated with the graph. There are plenty of applications of this line of research such as Google PageRank. Participants will first learn basic results from algebraic graph theory: adjacency, incidence, Laplacian matrices and their applications to walks, bipartiteness, connectedness, spanning trees, chromatic number of a graph. Then they will investigate various open problems such as finding similarity of incidence matrices of a graph and the Moore-Penrose inverse of a matrix associated with a graph or signed graph. This project will require generating examples of graphs and corresponding matrices using SageMath (a python-based open-source software). The ultimate goal is to write an article with the findings in this project and publish it in a research journal.
Recommended prerequisite: basic college level linear algebra and graph theory

Modeling disease outbreaks (advisor: Dr. Chanaka Kottegoda)

The 2009 outbreak of the H1N1pdm09 influenza A virus strain had a significant global impact, with the United States experiencing its introduction in April 2009. Despite extensive efforts to mitigate its spread, the virus rapidly propagated throughout the country. This project aims to deepen our understanding of the factors driving the outbreak and its rapid dissemination across various regions.

In this study, we employ mechanistic models to explore the dynamics of the H1N1pdm09 outbreak, with particular emphasis on the interaction between seasonal and climate-related factors and the loss of immunity within the population. Our objectives include calculating the next-generation matrix and determining the basic reproduction number ($R_0$) of the model to quantify transmission dynamics.

We plan to fit our model to H1N1pdm09 influenza case data from nine regions in the United States, and if time permits, extend the analysis to other countries. This regional focus allows us to investigate how variations in seasonal and climate forcing, combined with differences in immunity loss, contributed to the outbreak's spread in 2009. This study highlights the importance of understanding the complex interactions between viral mutation, seasonal/climate factors, and population immunity, providing a foundation for informed strategies to combat future influenza outbreaks effectively.
Recommended prerequisites: differential equations and linear algebra; experience with programming is helpful.

Combinatorial and algebraic properties of numerical semigroup rings (advisor: Dr. Aleksandra Sobieska)

A numerical semigroup is a subset of the natural numbers obtained by taking all the nonnegative integer combinations of some set. For example, using 3 and 7, we can generate the numerical semigroup {0,3,6,7,10,12,13,14,15,…}. Numerical semigroups appear anywhere that objects arise as combinations of specific numbers, both in advanced math and in the mundane – coins, stamps, football scores, and chicken nuggets.

To a numerical semigroup, one can associate a special ring called the numerical semigroup ring. The algebraic properties of the numerical semigroup ring are often closely related to the combinatorial properties of the semigroup. This project will focus on using minimal free resolutions – a way of encoding the algebraic structure of a ring into several matrices with polynomial entries – to quantify the algebraic properties of the ring, and look to connect these algebraic properties to the combinatorics of the semigroup.
Required Prerequisite: linear algebra; Recommended prerequisites: abstract algebra and some programming experience

Filtration of textile dyes (advisor: Dr. Sean McBride)

The purpose of this project will be to collect data for several new dyes during the functionalization process of porous polycarbonate filters, referred to as hysteresis data. During the functionalization process, the concentration of dyes run through the filter is increased from $50 \mu{M}$ up to $1000 \mu{M}$ and then back down to $50 \mu{M}$. If there was no hysteresis in the data during this cycle, then the rejection as a function of concentration for increasing and decreasing concentration would be the same and we would see no functionalization of the filter. However, for some anionic azo dyes, we see a large hysteretic behavior after ramping up and decreasing the concentration of the dyes run through the filter. The end goal of this research is to determine what variables or environmental conditions are responsible for this hysteric behavior for certain azo dyes. Once this is known, such attributes or combination of environmental parameters can be engineered in later research, leading to advanced dye removal systems.
