Professor and Director Graduate Studies
College of Engineering
Ph.D, University of California - Santa Barbara, 1991
M.S., University of California - Santa Barbara, 1987
B.S., EE California State Polytechnic University, 1983
I am originally from southern California, and got my Ph.D. at the University of California, Santa Barbara, where my advisor was Evelyn Hu. After finishing my Ph.D. I did a post-doc at Cornell University working for Harold Craighead. I�ve worked in industry twice. The first time was for two years at Motorola following my B.S. degree, and the second was for one year for Galileo Electro-Optics following my post-doc. I came to Notre Dame in 1994, and am currently serving as the Associate Chair for Graduate Studies for the EE Department.
Summary of Activities/Interests
My research in the last few years has focused on the design, fabrication, and measurements of micro and nanoelectronic devices. In the micro regime, my group works on CMOS circuits to study packaging issues, as well as to interface CMOS to nano devices. On the nano side, my research focuses on single-electron devices including Quantum-dot Cellular Automata (QCA) and single-electron transistors (SETs). QCA is a computational paradigm that offers ultra-low power dissipation and scalability down to molecular dimensions. SETs are the most sensitive electrometers known, and my group is investigating them for use in a variety of sensor applications. The limit for SETs has typically been the low operating temperature required, but resent developments in my group open the way for application in fields such as photo-detection and nanofluidics.
