About Me

I am an Assistant Professor in the Department of Statistics at George Mason University. I received my Ph.D. in Statistics from the Pennsylvania State University where I was advised by Dr. Murali Haran (Statistics) and co-advised by Dr. Klaus Keller (Geosciences). During my graduate studies, I was a part of the research network for Sustainable Climate Risk Management (SCRiM) and the Program on Coupled Human and Earth Systems (PCHES). 

My research interests include:

Looking to Collaborate?

Collaborators (and Coffee!): If you are interested in collaborating or just want to chat about research, feel free to reach out!  We can set up a meeting to discuss in-person or via Zoom. If you want to grab coffee on campus, we could drop by the Starbucks at the Johnson Center or Northern Neck

INOVA-GMU Collaborative Core: If you are an INOVA health care professional interested in collaborating with me through the GMU-INOVA Collaborative Core, please visit the collaboration homepage.

Students: I am also looking for motivated graduate students to join my research lab. If you have a background in statistical computing and/or are interested in applications in the environmental sciences, please send me an email. Our group will work on a variety of projects related to spatial and spatio-temporal statistics, uncertainty quantification and computer model calibration, Bayesian methodology development, and extreme value analysis in the climate sciences.
