Bio


Shirin Pourashraf was born in Darreh Shahr, Ilam, Iran, in Oct 1984. She received the M.S. degree from the Department of Electrical and Computer Engineering, Isfahan University of Technology, Isfahan, Iran, in 2011, and the Ph.D. degree from New Mexico State University, Las Cruces, NM, USA, in 2018.
Her field of studies was the design and test of low-voltage/low-power and high performance analog/digital/mixed-signal building blocks.
She authored seven journal papers during her Ph.D., and was the recipient of the Outstanding Teaching Assistant Award from the Klipsch School of Electrical and Computer Engineering, New Mexico State University, in 2017 and the Outstanding Graduate Assistantship Award from the Graduate School of New Mexico State University in 2018.
Dr. Pourashraf is currently a Postdoctoral Fellow Scholar in the Department of Radiology, Molecular Imaging Instrumentation Laboratory (MIIL) working on TOF-PET Imaging; specifically exploring, and designing instrumentation, and data acquisition electronics to improve time-of-flight resolution in PET detectors.
