Biography
Shamsoddin Mohajerzadeh was born in Tehran, Iran, in 1964. He received his undergraduate degree in electronics from the Sharif University of Technology, Tehran, in 1989 and the M.S. and Ph.D. degrees from the University of Waterloo, Waterloo, ON, Canada, in 1992 and 1996, respectively. He joined the University of Tehran as a lecturer in 1996, where he is currently an a Professor in the Department of Electrical and Computer Engineering. He has written more than 250 journal and conference papers and has filed three U.S. and one European patents. While studying for the Ph.D. degree, he worked on epitaxial growth of silicon and Si–Ge films on silicon. He is now interested in thin-film transistor fabrication on glass and plastic substrates, light emitting silicon-based nanostructures, flexible plasma display panels, carbon nanostructures and more recently deep micromachining of PET and silicon substrates.
