I joined Antonio Torralba's Lab at MIT CSAIL as a Postdoctoral Associate in October 2012. My research is in the field of computer vision and machine learning.

I graduated with a PhD in computer science from the University of California Irvine in September 2012. I was advised by Deva Ramanan and co-advised by Ramesh Jain. I was affiliated with the Computational Vision Lab and Experiential Systems Lab at UC Irvine.

I was born in Tabriz, a city in the north of Iran, and grew up in Tehran, capital of Iran. I got my MSc. in Electrical Engineering from Sharif University of Technology, Tehran, Iran (map) in Jan. 2006 under the supervision of Prof. Farokh Marvasti and Prof. Shohreh Kasaei.
