I am an Assistant Professor of Statistics at the University of South Carolina where I am also a McCausland Faculty Fellow. Before joining USC in 2020, I was a postdoc at the University of Pennsylvania for two years. I got my PhD in Statistics from the University of Florida, my MS in Applied Mathematics from the University of Massachusetts Amherst, and my BA from Cornell University. Prior to my career in academia, I worked in industry for five years as an engineer and as a financial software analyst. Here are the links to my CV and Google Scholar. If my work interests you, you are also welcome to connect with me on LinkedIn and Twitter.

My research group conducts research in the following areas of statistics and machine learning:
  • methods and scalable algorithms for high-dimensional data
  • deep learning for deep generative models and reinforcement learning
  • Bayesian methodology and computation
  • survival analysis and causal inference
  • clinical trials, drug discovery, GWAS, and other biomedical applications.
In Spring 2024, I am teaching STAT 721: Stochastic Processes. Course information


I will be able to take two or three new PhD students in Fall 2024. In order to work under my supervision, you must first pass the Statistics PhD Qualifying Exam (details here) in August 2024 — I cannot advise students who have not passed this exam. My hope is to have (at least) one new student work on Bayesian methods/algorithms and (at least) one new student work on deep learning problems. Potential projects within these areas include scalable Bayesian computation, generative modeling of non-IID data, causal inference, and competing risks. Information for prospective students
