Graduate Research Assistant
Department of Electrical and Computer Engineering
Chris joined the Nanoscale Materials and Device Group (previously known as the Knowlton Research Group) in the Fall of 2006 as a sophomore, undergraduate student studying Electrical and Computer Engineering (ECE). As an undergraduate, Chris worked in the Device and IC Characterization Lab and performed various electrical characterization techniques on different metal oxide field effect transistors and devices. He helped work on various projects involving the Variable Temperature Probe Station with low temperature characterization of High-k MOS devices. He also helped implement Low Noise Spectroscopy. Chris graduated in the Spring of 2009 with a B.S. in Electrical Engineering from Boise State University.
He is currently pursuing his M.S. in Electrical Engineering at Boise State University and is continuing to work with the Nanoscale Materials and Device Group. He is working with the DNA Nanostructures project. His current project is controlled placement of micro- and nano-sized particles and electrical characterization of novel, nanoscale devices.
