Patricia Gonzalez Guerrero

San Francisco is one of my favorite cities to visit.

I am currently a Postdoctoral Researcher in the Computer Architecture Group at Lawrence Berkeley National Laboratory.

Defended my PhD in Electrical and Computer Engineering at the University of Viriginia (UVA), Charlottesville, VA, USA

My PhD adviser professor Mircea Stan leads the HPLP research group at UVA.

My research in a nutshell

My research interests include ultra-low-power digital and mixed-signal SoC/ASIC/VLSI design for conventional and non-conventional forms of signal processing. My PhD work pioneered asynchronous computing with streams, where we developed the theoretical foundations for asynchronous stochastic computing and stochastic computing with sigma-delta streams.
