About Me

I am a research scientist at Facebook working on search ranking and retrieval for FB Marketplace.  Prior to that, I was leading the data science efforts for the Walmart Exchange (WMX) advertising platform @WalmartLabs, developing a machine learning and data science platform for enterprise at Skytree, and improving Amazon's product search relevance engine at A9.com.  Before that, I was developing machine learning techniques with the aim of understanding and modeling of precipitation patterns while teaching and mentoring students as an Assistant Professor of Statistics at Purdue University.

I earned a Ph.D. in Information and Computer Sciences from UC Irvine under the supervision of Padhraic Smyth.  I also received postdoctoral training with the Alberta Ingenuity Centre for Machine Learning (AICML) at the University of Alberta.
