11:15 am:
Biophysics Seminar in 120 PAN
Speaker: Prof. Marc Riedel University of Minnesota, Department of Electrical and Computer Engineering
Subject: T Computing with Crappy Clocks (C^3): A New Paradigm for Molecular Computing
Please note change of time from previous announcement. The seminar will be held at 11:15 for the remainder of the semester.

Clock distribution networks are a significant source of power consumption and a major design bottleneck for digital circuits, particularly with increasing variability. Completely asynchronous design methodologies have been studied for decades, but these have never gained widespread acceptance. We have proposed an alternative: splitting digital circuitry into small blocks and synchronizing these locally with independent, cheap clocks (generated with simple inverter rings). This is feasible if one adopts a stochastic representation for signal values. Logical computation is performed on randomized bit streams, with signal values encoded in the statistics of the streams. This talk will discuss extensions and applications of these ideas to molecular computing. DNA-based computation via strand displacement is the target experimental chassis.


Marc Riedel is Associate Professor of Electrical and Computer Engineering at the University of Minnesota. From 2006 to 2011 he was Assistant Professor. He is also a member of the Graduate Faculty in Biomedical Informatics and Computational Biology. From 2004 to 2005, he was a lecturer in Computation and Neural Systems at Caltech. He has held positions at Marconi Canada, CAE Electronics, Toshiba, and Fujitsu Research Labs. He received his Ph.D. and his M.Sc. in Electrical Engineering at Caltech and his B.Eng. in Electrical Engineering with a Minor in Mathematics at McGill University. His Ph.D. dissertation titled "Cyclic Combinational Circuits" received the Charles H. Wilts Prize for the best doctoral research in Electrical Engineering at Caltech. His paper "The Synthesis of Cyclic Combinational Circuits" received the Best Paper Award at the Design Automation Conference. He is a recipient of the NSF CAREER Award.
