About me
Hi, I am an Associate professor in the Department of Electrical and Computer Engineering at the University of Massachusetts Lowell. Before UMass Lowell, I spent a 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. Earlier than that, I was a research staff member at ETRI (Electronics and Telecommunication Research Institute), South Korea.
