Short Bio

I'm an assistant professor in the Department of Mathematics and Computer Science at Emory University. I received my Ph.D. from the Electrical and Computer Engineering Department at UT-Austin, co-advised by Dr. Joydeep Ghosh (Intelligent Data Analysis Exploration Lab) and Dr. Sriram Vishwanath (Laboratory for Informatics, Networks, and Communications). I'm also a co-founder and the chief data scientist of Accordion Health. We are a healthcare data analytics startup that provides targeted guidance using predictive analytics.

Prior to UT, I graduated from MIT with a B.S and M.Eng degree from the Electrical Engineering and Computer Science Department. After graduation, I worked at Lawrence Livermore National Laboratory on various projects before returning to graduate school. For more details, view my CV.
