For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all. So we fix our eyes not on what is seen, but on what is unseen. —— 2 Corinthians

About Me

I am a software engineer at Amazon for data engine storage layer and real-time monitoring components for Redshift. I completed my Ph.D. in the College of Information and Computer Sciences at University of Massachusetts Amherst, advised by Prof. Yannis Smaragdakis.

My research interests span over program analysis, automated test case generation, verification of systems, and image processing.

My CV is here.
