I am an Assistant Professor in the Department of Computer Science and Engineering at Ohio State University. I lead the Architecture Research Lab at OSU. Our research interests include computer architecture, nanoscale technology scaling, reliability, variability and power management. I received my Ph.D. from the Department of Computer Science, University of Illinois at Urbana-Champaign where I was a member of the IACOMA group working with Prof. Josep Torrellas. I was the recipient of an Intel Foundation Fellowship for 2007-2008 and the W. J. Poppelbaum Award for 2008.
A high-level summary of my research has been published recently in the Spring 2013 CSE Newsletter. For more details and research updates please visit my group’s website.
I won an NSF CAREER award titled An Integrated Treatment of Voltage Noise and Process Variability in Many-core and GPU Systems with Microarchitectural Solutions. Here are the CSE department and College of Engineering announcements with brief overviews.
We are looking for very bright and motivated students to join us. If you are interested in working with us send me an email or drop by my office.
