Sujaya Maiyya

Assistant Professor

University of Waterloo

I am an assistant professor at Cheriton School of Computer Science at University of Waterloo. Prior to joining Waterloo, I did a short postdoc at Cornell University. I received my PhD from UC Santa Barbara where I was co-advised by Amr El Abbadi and Divy Agrawal.

Research Interests: My research interests broadly lie in distributed systems & databases and data privacy & security. I design, prototype and evaluate protocols for managing large-scale data in a performance efficient and secure manner. My research intersects 3 facets of database systems: performance, fault tolerance, and security.

Prospective Students: I am looking for highly-motivated PhD and MSc students with full funding opportunities. If you are interested in working with me on systems research, please send me an email and mention my name as a potential advisor in your application.
