David Lion
I am a sixth year Ph.D. student in the Department of Electrical and Computer Engineering at the University of Toronto. I received a Bachelor of Applied Science and Masters of Applied Science from the same department.
I focus on computer systems, under the supervision of my supervisor Ding Yuan.
