An Introduction to the Fundamental Gap Problem
Abstract:
In this presentation, we will introduce the problem of establishing a lower bound on the difference between the first two eigenvalues of a Schrödinger operator with Dirichlet boundary conditions on a bounded convex domain in a smooth manifold. We will introduce the general problem and illustrate it with a simple, concrete example.
We will then work through the foundational calculations underlying an early result for convex domains in n-dimensional Euclidean space (Singer, Wong, Yau, and Yau, 1985). We will establish the required log-concavity of the first eigenfunction and develop the gradient estimate needed to derive the lower bound.

Breast cancer methylation age analysis with the incorporation of vital status and clinical information
Shuying Sun
Texas State University

Abstract: Breast cancer is associated with epigenetic changes such as DNA methylation and risk factors like
age, which itself is also linked to methylation changes. Previous studies have developed models to estimate
age from DNA methylation (DNAm age), such as the Horvath clock (with 353 CpG sites). Prior research has
used such clocks to analyze methylation in breast cancer. However, to our knowledge, no prior analysis has
considered patients’ vital status, and the original Horvath clock was not built with breast cancer-specific
clinical information such as hormone receptor status (ER and PR) or tumor stage in mind.
To address these gaps, we conducted a two-part DNAm age analysis using publicly available breast cancer
methylation data, stratified by vital status (Alive, Dead) and tissue type (Tumor, Matched Normal) into four
datasets: Alive Normal, Alive Tumor, Dead Normal, and Dead Tumor. In Part I, we examined relationships
between DNAm age, chronological age, clinical information and differentially methylated (DM) sites across
the four groups. In Part II, we built a regression model for each CpG site, with methylation level as the
response and chronological age, ER status, and PR status as covariates, and identified CpG sites where
methylation was significantly associated with age within each dataset. We further studied these sites and
their associated genes.
Our findings provide the first systematic comparison of DNAm age patterns between alive and dead breast
cancer patients. We show that vital status and clinical information are critical but previously overlooked axis
of variation in epigenetic aging analysis. This work offers a new understanding of DNAm age in breast cancer
and lays the groundwork for breast cancer-specific, vital-status-aware biomarkers for diagnosis, prognosis,
and treatment. Click here for more information

Exploring Graduate Students' Identities Through Narrative and Correspondence-Based Approaches

Abstract: Graduate students' experiences in mathematics are deeply tied to the development of their mathematics and professional identities. I share two studies to illustrate how narrative and correspondence based-methodologies can provide rich insights into graduate students' lived experiences and identity development in graduate mathematics education. The first study employs narrative inquiry and restorying to examine how masculine discourses shaped women's experiences within a graduate mathematics context. The second study explores the use of "Dear Math..." letters alongside interviews, demonstrating how reflective writing and elements of correspondence research can access participants' understandings of their relationships with mathematics and their emerging identities. I aim to highlight methodological possibilities for investigating graduate students' experiences while also offering insights into the ways identities are negotiated within graduate mathematics education.  Click here for more information
