Mathematics & Statistics | Today at Elon | þ /u/news Thu, 16 Apr 2026 20:03:42 -0400 en-US hourly 1 Hwayeon Ryu conducts international research collaboration and delivers colloquium talk at the Sydney Mathematical Research Institute /u/news/2026/04/09/hwayeon-ryu-conducts-international-research-collaboration-and-delivers-colloquium-talk-at-the-sydney-mathematical-research-institute/ Thu, 09 Apr 2026 15:38:26 +0000 /u/news/?p=1043617 Hwayeon Ryu, associate professor of mathematics, recently visited the at the University of Sydney, Australia, from March 23 to April 7 through its international visitor program. During her visit, she initiated a new international research collaboration with Peter Kim, professor of applied mathematics at the University of Sydney (host institution), and Adrianne Jenner, senior lecturer (equivalent to assistant professor) at Queensland University of Technology, to investigate the potential link between Epstein–Barr virus (EBV) infection and the onset of multiple sclerosis (MS).

The primary goal of this project is to investigate the link between EBV and MS using a virtual clinical trial framework by testing three hypotheses: EBV resurgency, impaired B cell regulation, and molecular similarity between EBV antigens and myelin in genetically predisposed individuals.

The team has developed a within-host mathematical model of EBV infection, building on existing frameworks that incorporate epithelial and B cell dynamics, to examine which mechanisms are most likely to drive disease onset, with a current focus on immune cross-reactivity. The model will be further extended to include autoreactive immune responses and myelin damage, providing a more comprehensive representation of MS-related pathology.

During her visit, Ryu also delivered a colloquium talk titled “Immune Dysregulation in COVID-19: What Can Mathematical Modeling Tell Us?” based on her recently published work supported by the National Science Foundation. In the talk, she addressed why some individuals experience mild COVID-19 while others develop severe disease, presenting a mathematical framework that captures interactions between SARS-CoV-2 and the immune system. Through computational simulations and sensitivity analysis, she demonstrated how variations in immune responses can lead to divergent disease trajectories and highlighted key mechanisms that influence disease progression.

Following her time in Sydney, Ryu will travel to the University of Melbourne in late April to help organize a two-week workshop, “Collaborative Workshop for Under-Represented Genders Advancing Mathematical Biology,” co-organized with Jenner. This will be held at for the mathematical sciences in Australia near the campus of the University of Melbourne.

These visits provide valuable opportunities to advance interdisciplinary collaboration and strengthen international research connections in mathematical biology.

Biomedical engineering major, mathematics and biology faculty collaborate on research, connecting disciplines /u/news/2026/04/03/biomedical-engineering-major-mathematics-and-biology-faculty-collaborate-on-research-connecting-disciplines/ Fri, 03 Apr 2026 12:30:19 +0000 /u/news/?p=1042830 To Elise Butterbach ’27 a biomedical engineering student, research is not contained to a single field of study, it exists at the intersection of many fields.

Butterbach’s path to research started in a cell biology course taught by Assistant Professor of Biology Efrain Rivera-Serrano, where she consistently asked questions and engaged deeply with the material. This curiosity led her to join the interdisciplinary project.

“It was a very ‘right place, right time’ circumstance,” Butterbach said. “This research was exactly the sort of thing I was looking to get involved in.”

Through her Lumen Prize, Butterbach is working alongside two faculty mentors from different fields of study, Associate Professor of Mathematics Hwayeon Ryu and Rivera-Serrano, to study viral myocarditis, or heart inflammation, that occurs during the infection of many viruses. Her research is focused on examining the pathways that lead to excessive inflammation and how inflammation can be reduced without compromising the immune system’s ability to clear the virus.

“My research focuses on creating math out of biological reactions,” Butterbach said. “Ultimately, the goal is to create a framework that helps us better understand and predict how cardiac inflammation progresses.”

Viral myocarditis occurs when inflammation damages heart tissue, sometimes leading to long-term complications or sudden cardiac failure, particularly in young, active individuals. Although inflammation is a natural immune response, Butterbach’s research is exploring what causes that response to become excessive.

Butterbach uses mathematical modeling to integrate biology and immunology into a modeling framework to identify factors that most strongly drive harmful inflammation, revealing pathways that could be therapeutically targeted.

“It’s a balancing act to use equations to model what’s happening,” Butterbach said. “If the model is too simple then it is not realistic to the human heart, but if the model is too complex, it becomes difficult to work with.”

Taking an interdisciplinary approach

This research project’s strength lies in its collaboration and intersection between mathematics, biology and engineering. Mathematics offers the language and tools to create the models, while biology provides the foundation for understanding the disease. Engineering ties it together through design, problem-solving and a systems-level mindset.

“This project works precisely because it sits at the intersection of all three areas,” Rivera-Serrano said. “Elise is especially well suited for this work because she is genuinely interested in connecting these disciplines rather than treating them as separate silos.”

Ryu echoed this statement on Butterbach’s interdisciplinary approach.

“Elise approaches research with a rare combination of intellectual curiosity, maturity and persistence, and she is genuinely committed to understanding how mathematics and biology inform one another,” Ryu said. “Her ability to engage across disciplines and contribute thoughtfully at that intersection is what makes her such a strong and promising researcher.”

Butterbach, Rivera-Serrano and Ryu meet weekly to refine their model, troubleshoot challenges and discuss literature.

“The steady back-and-forth is one of the strengths of the project,” Rivera-Serrano said.

For Butterbach, working across disciplines has shaped how she approaches problems.

“I’ve always found that when different disciplines collide, it actually becomes easier to understand complex concepts,” Butterbach said. “Working across engineering, mathematics and virology is fascinating because each discipline approaches the same problem in a completely different way. Learning to think adaptively across disciplines and translate between them has been one of the most valuable parts of this experience.”

Butterbach is motivated by the possibility of using interdisciplinary research to better understand human disease.

“The interdisciplinary nature and the way the team bring together mathematics, biology and engineering is not always easy to achieve, but Elise has embraced it fully and become an essential part of that process,” Ryu said.

Collaborating on this research has been rewarding not only for Butterbach, but for her mentors as well.

“Working with Elise has been incredibly rewarding,” Rivera-Serrano said. “She approaches a difficult project that requires her to be conversant in multiple disciplines with curiosity, maturity and persistence.”

One takeaway she learned from working in disciplines outside of her major is that discoveries in one field almost always influence others.

“By learning how to think like a biologist, a mathematician and a physicist, I have become much more comfortable applying ideas from one subject to another, even when they seem unrelated at first.”

She also values the work with her two mentors, Rivera-Serrano and Ryu, as they have helped her grow as a researcher.

“Dr. E spends a lot of time looking for resources that I can use to calculate the values of different parameters,” Butterbach said. “Similarly, Dr. Ryu works tirelessly to not just improve my mathematical skills but also teaches me how to see mathematical theory working in the real world. They’re not just dedicated to this project; they’re also thinking about what comes next for me.”

Expanding her research

Butterbach was recently selected for a competitive Physical, Engineering and Biology Research Experiences for Undergraduates program at Yale University, focused on physics, engineering and biology. Butterbach hopes to expand her research on the cardiovascular system.

“Elise’s acceptance is especially meaningful because it reflects national-level recognition of her promise as an þ researcher in an interdisciplinary space,” Rivera-Serrano said.

For Butterbach, the opportunity was surprising and motivating.

“I tried not to set any grand expectations for myself, so when I received the email I was genuinely surprised to be selected for the program,” Butterbach said. “It felt incredibly validating of the hard work and dedication I’ve put into my studies.”

At Yale, the program, like her research, is interdisciplinary covering biology, physics and engineering. She will expand her experience in computational and biological modeling while working alongside researchers.

“To me, this program represents the opening of new doors,” Butterbach said. “It’s an opportunity to continue growing as a researcher, meet people working at the forefront of interdisciplinary science and explore new directions that I may not have encountered otherwise.”

Baseball Analytics Club members participate in National Case Competition /u/news/2026/03/10/baseball-analytics-club-members-participate-in-national-case-competition/ Tue, 10 Mar 2026 20:26:05 +0000 /u/news/?p=1041343 Five students from Elon’s Baseball Analytics Club participated in a case competition at the SABR Analytics Conference in Phoenix, Arizona at the end of February.

The competition included 17 teams, from 9 schools, and each team presented their work for judges from professional baseball teams and companies. Teams were given one week to develop an analytics-based approach to determine when certain power hitters should adjust their plan at the plate to favor more contact. The teams needed to decide on an approach, gather and clean data, analyze the data, and produce a 20-minute presentation during that time. Elon’s team collected data from four different sources to build a model accounting for batter and pitcher ability, situational importance, ballpark-specific factors, and weather. Part of their approach included using existing situations where batters might already adjust their plan to determine which hitters have the greatest capacity to make adjustments.

Elon has been sending a team to this competition for a decade, and several former members have secured jobs with professional baseball teams after graduation. Jackie Jovanovic ’23, who represented Elon in the competition twice, returned this year as a judge for the competition. She is now working for the Miami Marlins as a Junior Data Scientist.

Elon College, the College of Arts and Sciences, launches new mission, vision and core values /u/news/2026/02/27/elon-college-the-college-of-arts-and-sciences-launches-new-mission-vision-and-core-values/ Fri, 27 Feb 2026 15:13:11 +0000 /u/news/?p=1040355 Elon College, the College of Arts and Sciences, introduced a new mission statement, vision statement and core values during its spring faculty meeting following a year and a half-long process led by Dean Hilton Kelly.

Since his 2023 arrival at Elon, Kelly has hosted a ‘listening tour’ and spent time with each department to hear directly from faculty and staff about what they value. Kelly said that common themes soon emerged from those conversations and the new statement reflects dozens of discussions.

Elon College, the College of Arts and Sciences new vision statement reads: “The Heart of an Elon Education: Ignite Curiosity, Engage Challenges, Transform Worlds.”

The mission statement then declares:

“Upholding the centrality of the liberal arts, we explore and apply disciplinary and interdisciplinary knowledge for inquiry, creativity, discovery and problem solving in a complex and changing world.”

The statement lists core values that include accessibility, belonging, critical thinking, diversity, equity and inclusion, integrity, intellectual curiosity, problem-posing and respect for human dignity.

Community Reflections

  • “There were several opportunities for different groups, departments, branches, interdisciplinary programs, to discuss versions on the table. It was in those conversations where we might learn how a word or phrase was heard within and across disciplines; where we found convergence, deeper awareness, and respect. The both-and of this process modeled what we value and genuinely captures our shared identity as Elon College.” – Caroline Ketcham, associate dean of Elon College, the College of Arts and Sciences and a professor of exercise science
  • “It was always important to us that this wasn’t a process where faculty were just asked to weigh in at the end, after the real decisions had already been made. From start to finish, it was grounded in listening to what faculty across the college say we do well and what values they believe guide our shared work. Our task wasn’t to invent a mission, vision and values, but to clearly articulate what faculty are already living and leading with. I think that’s why faculty can so readily see themselves and their departments represented in the final statements.” – David Buck, associate dean of Elon College, the College of Arts and Sciences and an associate professor of psychology
  • “Having shared goals and articulated values helps everyone in the college feel connected as a community, value each other’s work and prioritize our energies on initiatives that matter to us.” – Shannon Duvall, interim associate dean of Elon College, the College of Arts and Sciences and professor of computer science
  • “I appreciated the collaborative nature of it all, not just between the dean’s office and department chairs, but also extending to faculty members across Elon College, the College of Arts and Sciences. It really did involve all of us. What particularly stood out to me were the conversations in our chairs’ meetings with the dean where we came to agreements on core values. It’s inspiring to see that distinctly different types of disciplines uphold the same core values.” – Joel Karty, chair of the Department of Chemistry and þ’s Sydney F. & Kathleen E. Jackson Professor of chemistry
  • “I appreciated being part of a process that felt genuinely collaborative. Our participation was not merely symbolic. It felt meaningful, and I experienced the dean’s office as truly listening. The process itself was also inspirational, and I feel bolstered in leading my own department through similar work. It was powerful to see such a broad, collective effort take shape into something tangible.” – Samantha DiRosa, chair of the Department of Art and a professor of art and environmental studies
  • “The process of creating a new vision statement, mission statement and core values for Elon College, the College of Arts and Sciences was both thoughtful and deeply collaborative. Over many months, department chairs worked together to reflect on what makes us distinctive and how best to express those qualities in guiding statements. The process intentionally sought input from across departments, ensuring that everyone in the college had the opportunity to contribute their perspectives. Personally, the time spent reflecting with fellow chairs on what makes each of our departments special fostered a deeper sense of shared purpose and collective commitment.” – Carrie Eaves, chair of the Department of Political Science and Public Policy and associate professor of political science and public policy

Kelly said he was pleased the final language resonated with the faculty in the college.

“The true measure of a successful attempt to lead a group or an organization towards a renewed vision, mission and core values is whether the words and sentiments ‘sound like us’,” he said. “When I heard that some faculty believed my presentation of our vision, mission and core values at our spring faculty meeting ‘sound like us,’ I knew that our work together in small and large group settings was a huge success. It means that stakeholders were heard and that the words resonate so much so that the tune or melody is familiar. The vision, mission and core values reflect truly who we are and where we are going with much intention.”
