Bio

I am a fourth-year Ph.D. candidate at Florida International University, where I am advised by Professor Christian Poellabauer. My research interests include machine learning, natural language processing, and speech processing, particularly in how these fields can be applied to healthcare applications.

Before joining FIU in the fall of 2021, I earned my B.S. degree in Mathematics from the University of Kansas in 2017 and my M.S. degree in Business Administration from La Salle University in Pennsylvania in 2018. Following my studies, I worked as a financial analyst for various companies until 2021.
