I’m a PhD student in Brown CS.
My sensei are Stan Zdonik, Seny Kamara, and Tarik Moataz. I also collaborate with Ugur Cetintemel, Carsten Binnig and Tim Kraska in the Database Group, Emanuel Zgraggen in the Graphics Group, and Eli Upfal and Lorenzo De Stefani in the Theory Group.
I am interested in the theories and designs of big data systems that are intelligent and safe. My current study focuses on end-to-end encrypted, provablely secure relational databases (SQL).
In the past, I have also dabbled in constraint learning for puzzle-solving AI, false-discovery control in data science, approximate data structures for visualization, database design on hybrid memory, consistency control for stochastic machine learning algorithms, and searchable encryption on mobile text messaging.
