Ehsan Afshari
Ehsan Afshari is an Iranian-American electrical engineer, researcher and academic. He is Professor of Electrical and Computer Engineering at University of Michigan. Afshari's research is focused on high frequency circuits and systems for imaging, bio-sensing, and high data rate communications. He has written over 150 papers. He was the recipient of the 2008 DAPRA Young Faculty Award and the 2010 NSF Early CAREER Award. Education. Afshari received a B.Sc. in Electrical Engineering from Sharif University of Technology in 2001. He then moved to the United States, where he joined California Institute of Technology, completing his  M.Sc. in Electrical Engineering in 2003 and his Ph.D. in Electrical Engineering in 2006. Career. After completing his Ph.D., Afshari joined Cornell University as an assistant professor, becoming associate professor in 2012. In 2016, he joined University of Michigan as an Associate Professor of Electrical and Computer Engineering. In 2019, he became Full Professor at University of Michigan. As a result of his research, Afshari co-founded Airvine and Lassenpeak. Afshari has been an advisor to many PhD students that became faculty members at major universities. Research and work. After completing his Ph.D., Afshari changed his research focus to terahertz  circuits and systems. When he began research in this area, most of the terahertz systems used expensive and bulky devices such as quantum cascade lasers. Starting from 2010, Afshari's team started to develop circuit blocks and systems operating at terahertz frequencies using conventional transistor technologies. One of the early milestones of his group was the design and fabrication of the first integrated oscillator operating above 400 GHz which generated more than 100 uW of power. At the time of design, this oscillator generated three orders of magnitude higher power compared to prior art. His team has continued advancing the  terahertz electronics research and have designed the first terahertz voltage controlled oscillator (VCO), the first 2-dimensional terahertz phased array, the highest frequency active multiplier, the first fully integrated frequency modulated continuous wave (FMCW) radar operating above 200 GHz, and the first phase-locked terahertz imaging transceiver chipset all based on standard Si/SiGe technologies. Aside from these designs, Afshari's team has been active in other areas of research including but not limited to low-phase-noise radio-frequency VCO's, high-power and power-efficient mm-wave oscillators, and non-boolean pattern recognition circuits.
