Reza Vatanmeidanshahi received M.S. degrees in Material Chemistry and Physical Chemistry from Sharif University of Technology, Iran in 2011 and from Arizona State University (ASU) in 2014, respectively and the PhD degree in Electrical Engineering from ASU in 2019. Reza is currently a Postdoc student in Professor Goodnick's lab at ASU. Reza has passion to simulate and model semi-classical charge transport in semiconductors, for device application, in different length scales by means of density functional theory, molecular dynamics, Monte-Carlo algorithms, machine learning method and classical physical models. In ULTRA, Reza focuses on implementing new algorithms into in-house full-band cellular Monte-Carlo code in order to model and calculate high-field charge transport and defect assisted impact ionization coefficients in ultra-wideband gap semiconductors.
