Title: Modules with descending chain conditions in summable families of endomorphisms.
Abstract: Two elements a, b in a ring R form a right coprime pair if aR + bR = R. In this talk, we will define right strongly exchange rings in terms of descending chains of right coprime pairs, and we will show that they are semiregular. We will also demonstrate that the class of right strongly exchange rings contains left injective, left pure-injective, left cotorsion, local, or left continuous rings. This allows for a unified study of all these classes of rings in terms of the behavior of descending chains of right coprime pairs.

We will also extend this concept to coprime summable families of endomorphisms of a module and provide a general criterion to determine when a module satisfies the full exchange property. In particular, we will use this criterion to prove that flat cotorsion modules enjoy this property.

Title: Becoming a Mathematician: A Journey Shaped by Community
Abstract: In this talk, I share my path in mathematics, beginning with real struggles in 8th-grade Algebra and culminating in a PhD and a career as a professor. My journey was shaped early by a teacher who believed in me and by communities that offered both support and honest guidance when things felt out of reach. That foundation carried me from majoring in mathematics at Xavier University of Louisiana to earning my PhD at the University of Nebraska–Lincoln, where I was among the first two African Americans to do so.

Those experiences continue to shape how I think about mathematics, education, and belonging. Today, my work centers on helping students see that there is more than one way to succeed in STEM and that persistence is often built through community rather than in isolation. Through leadership and mentoring roles, I strive to create spaces where students feel supported, challenged, and seen.

I will also offer a glimpse into my everyday life as a mathematician, including how teaching, mentoring, and research fit together in an academic career. My goal is to demystify what mathematicians do, share what sustained me through setbacks, and emphasize how guidance, encouragement, and purpose can open doors. I hope this talk helps students recognize their own potential and imagine a future in mathematics or other STEM fields that feels both attainable and meaningful.

Math For All Conference in St. Louis - April 11, 2026

The Math For All conference has the purpose of fostering inclusivity in mathematics by holding talks and discussions in both research and education. This conference will be targeted to undergraduate and graduate students, post-docs, and faculty members from all institutions and its main goal is to provide a friendly, open environment to learn and discuss mathematics.

Registration and abstract submissions are open! Please visit the event website for more information: https://sites.google.com/view/mathforallnola/in-person-locations/saint-louis-mo?authuser=0
