I joined the Department of Statistics at the University of South Carolina as an Assistant Professor in 2020. From 2018 to 2020, I was a postdoc at the University of Pennsylvania, supervised by Yong Chen and Mary Boland. I received my PhD in Statistics from the University of Florida in 2018 under the supervision of Malay Ghosh. I earned my BA from Cornell University and an MS from the University of Massachusetts Amherst, and I also worked in industry for five years as an engineer and as a financial analyst.

My research group focuses on Bayesian statistics, high-dimensional modeling, and scalable machine learning algorithms for large and complex data sets. Our research is primarily motivated by addressing “big data” challenges in contemporary biomedical and public health problems, including genome-wide association studies, computational drug repositioning, data integration, and analysis of electronic health records.

In Spring 2022, I am teaching STAT 721: Stochastic Processes.
