About me

Hi, I am an assistant professor in the department of Electrical and Computer Engineering at University of Massachusetts Lowell. Prior to UMass Lowell, I spent great many years as a postdoctoral researcher in the Electrical Engineering and Computer Science department at Northwestern University and the Math and Computer Science division at Argonne National Laboratory. I received my Ph. D degree in Computer Science and Engineering from The Pennsylvania State University in 2008. While at Penn State, I was advised by Prof. Mahmut Kandemir. Earlier than that, I was a research staff member at ETRI (Electronics and Telecommunication Research Institute), South Korea.
