I am an assistant professor in mathematics at Louisiana Tech University in Ruston, LA.
Research Interests
My research is in algebraic number theory and focuses on special values of zeta functions, multiple zeta functions and L-functions in function fields. In particular, I apply techniques from Drinfeld modules to study these special values. One of the main goals driving my research is to understand the transcendence of and algebraic relations between these special values.
Funding
My work is currently supported by:
Research Competitiveness Subprogram grant (RCS) funded by the Board of Regents of the state of Louisiana - 06/23 through 06/26 - $148,109
NSF Algebra and Number Theory grant 2302399 - 09/23 through 09/26 - $139,074
Interdisciplinary Art Grant
In 2019-2020 I worked with UCSD MFA student Grace Grothaus to create a visual represenation of my research in transcendental number theory. Here is a small sample of the completed project, called "Transcendere". Our work was funded by a mini-grant from the Research Communications Program of UCSD Physical Sciences.
You can also see a short video clip showing the effect the iridescent inks give the painting. The painting is displayed in the AP&M building at UCSD.
