Welcome!

Introduction

I am a Principal Researcher at Microsoft, working on AI systems. My academic background includes faculty positions in Computer Science and Engineering at the University of Notre Dame and in Computer Science at the University of Nebraska, where I directed research groups of 10+ members, including software engineering and research staff, postdocs, as well as graduate and undergraduate students. Throughout my academic career, I have been awarded multiple grants from federal, state, foundation, and industry sources. I hold a Ph.D. and an M.Sc. in Computer Science from UCLA and an M.Eng. in Electrical and Computer Engineering from the National Technical University of Athens.
