Bio
Bill Fefferman was a Research Assistant Professor in QuICS and a Research Scientist at NIST from 2018-2019. His work focused on quantum computation and computational complexity theory, with an emphasis on understanding the capabilities of near term quantum devices and experiments. He previously held postdoctoral positions at UC Berkeley advised by Umesh Vazirani, and at the University of Maryland in QuICS. He received his doctorate from Caltech in 2014, advised by Alexei Kitaev and Chris Umans. In 2017 he was the recipient of a Young Investigator Award from the Air Force Office of Scientific Research to help support his research on the power of near-term quantum systems. Bill is an Assistant Professor at the University of Chicago.
