Biography
I received the B.Sc. degree in computer engineering from Ferdowsi University of Mashhad in 2011, and M.Sc. degree in computer engineering from Sharif University of Technology (SUT) in 2013. I received the Ph.D. degree from Sharif University of Technology (SUT) in 2018 under supervision of Prof. Hossein Asadi at Data Storage, Networks, and Processing (DSN) lab. I was a postdoctoral researcher in Efficient Computing and Storage Group at Johannes Gutenberg-University Mainz under supervision of Prof. André Brinkmann. Currently, I am a substitute professor at Johannes Gutenberg-University Mainz. My research interests include operating systems, solid-state drives, and data storage systems.
