Khuzaima Daudjee

I am a professor in the research stream in the Cheriton School of Computer Science at the University of Waterloo.

I am interested in systems-oriented research. I work at the intersection of distributed systems and data management, particularly on building large-scale systems, storage and infrastructure in the cloud and on modern hardware. I am affiliated with two research groups: Systems & Networks and Data Systems.
