In Brief: I am a postdoc at the The McCourt School's Massive Data Institute at Georgetown University, where I am supervised by Lisa Singh and Ali Arab. We study forced migration using penalized inference and Variational Bayes[1].

My thesis research in statistics [1], supervised by Bobby Gramacy at Virginia Tech, was on surrogate modeling for black-box optimization and sensitivity analysis [2][3].

I also have the privilege of being involved in a neuromorphic computing (brain-like neural nets) collaboration [1][2][3] with Fangfang Xia at Argonne National Lab.
