About Me

I am a Ph.D. student in Computer Science and Engineering at Paul G. Allen school of Computer Science and Engineering, University of Washington. Currently, I am working in Networks and Mobile Systems Lab as a research assistant under supervision of professor Shyamnath Gollakota where I work on low-power communication system and embedded system design. I earned my M.S. in Electrical Engineering from EE Department at University of Washington, in 2017. In 2015, I received my B.Sc in Computer Engineering at CEIT department, Amirkabir University of Technology, Tehran.
