I currently work for Intel Labs in Hillsboro, Oregon. I graduated with a Ph.D. in Computer Science from the University of Virginia in May 2009. Till then, I was a member of the LAVA lab and was working under the guidance of Prof. Kevin Skadron in the areas of Temperature and Power-Aware Microarchitecture. My co-advisor was Prof. Mircea Stan who heads the HPLP lab. I got my Bachelor's degree from the Department of Computer Science and Engineering of the College of Engineering Guindy (CEG), Anna University in Chennai, India. My undergraduate work was under the guidance of Prof. Ranjani Parthasarathi in the area of Reconfigurable Computing. I come from Madurai - an ancient "Temple City" in South India. My high school education was from the TVS Lakshmi Matriculation Higher Secondary School in Madurai and primary education was from Dr. Nalli Kuppuswamy Vivekananda Vidyalaya in Chennai.
