# Research

I am an Assistant Professor at Purdue University in the ECE department. My current research focuses on machine learning in general and causal inference and learning algorithms from data in particular. Specifically, I have been developing algorithms for learning causal graphs from observational and experimental data using tools from information theory and graph theory.
