About Me

My name is Ben Seiyon Lee, and 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:

  • computational methods for high-dimensional hierarchical spatial / spatio-temporal models

  • statistical methods and parallelized algorithms for computer model calibration

  • uncertainty quantification

  • Bayesian hierarchical modeling

  • interdisciplinary research in the environmental sciences

I am also part of the GMU-INOVA Health Systems iTHRIV partnership where statistical experts at George Mason University are available to provide support to colleagues from Inova Health Care Services. For additional information please visit the collaboration homepage.
