I am a Ph.D. student at UWaterloo advised by Prof. Semih Salihoglu. I am a member of the Data Systems Group and I work on Graphflow, an active graph database.
I am interested in various models and applications of data systems. My current work focuses on query execution and optimizations as well as development of auxiliary data structures to evaluate graph database queries efficiently.
