I am an Assistant Professor of Statistics at the University of South Carolina (USC). 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.

Prospective Students

To work with me, you must be currently enrolled as a student at USC. PhD students who are potentially interested in my supervision must also first pass the USC Statistics PhD Qualifying Exam (offered every August). Information for prospective students

If you are interested in applying to the Statistics graduate program at USC but are not yet enrolled there as a student, please visit the department webpage for information about applying. Note that graduate students are admitted by the department’s Graduate Admissions Committee — not by myself or individual faculty. I am also unable to provide specific feedback on anyone’s application or recommend applicants whom I do not know for admission.
