About Me

My name is Hadi Khodabandeh (persian: هادی خدابنده, click here for pronunciation), I am a 6th year Ph.D. of Computer Science in University of California, Irvine and a part-time student researcher at Google. My area of study is theoretical computer science (TCS) and my focus is on graph theory and computational geometry. I am honoured to be advised by professor David Eppstein. Feel free to check out my scholar page to learn more about my research.

You can find me in the theory office, DBH 4099, or by contacting me via khodabah at uci dot edu.
