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.
Email / Résumé / Github / Twitter
I am interested in various models and applications of data systems.
My current work focuses on optimizations for query execution and development of auxiliary data structures to evaluate graph database queries efficiently.
