Profile
I'm glad you found my profile! I'm an assistant professor of AI and data science at AIU where I have been since 2024.
I completed by undergraduate studies at The Ohio State University in 2019 with a double major in mathematics and physics. Immediately after graduation, I began a PhD in statistics at North Carolina State University where I was advised by Brian Reich and Srijan Sengupta. In 2023, I spent seven months at Tokyo Institute of Technology on a JSPS fellowship working with Petter Holme and Tusyoshi Murata. I finished my PhD in 2023 and started at AIU in 2024.
Research Field
I have two main research interests which recently have found some overlap. First, I study networks. Networks are a simple way to represent complex relationships between entities. I consider well-known network structures, e.g., community and core-periphery, and seek to formalize them from a statistical angle.
Second, I am interested in Bayesian inference, particularly in deriving principle prior distributions for scale parameters in hierarchical models. It is a well-known challenge to elicit priors for scale parameters, and I have applied my work to generalized linear mixed models and spatial regression models. Recently, I have also been interested in Bayesian Optimization (BO), a paradigm for optimizing complicated objective functions. I have applied this work to the influence maximization (IM) problem in network science, and can be applied to many other interesting domains.
