Mohammad Shahrad

I am an Assistant Professor in the Department of Electrical and Computer Engineering at the University of British Columbia (UBC) and an Associate Faculty Member of UBC's Department of Computer Science. My research focuses on building more efficient and sustainable large-scale computing systems. I am an enthusiastic, hands-on researcher with experience in multiple layers of abstraction, from circuits to large-scale cloud systems. My primary research domain is cloud resource management, more recently in the context of serverless systems. I lead the UBC Cloud Infrastructure Research for Reliability, Usability, and Sustainability (CIRRUS) Lab.
