Siddhartha Sahu

---

Hi! I obtained my PhD at the David R. Cheriton School of Computer Science at the University of Waterloo.

I researched graph processing systems with Prof. Semih Salihoglu as part of the Data Systems Group.

Research Interests

I am excited about highly scalable data processing systems. In my research, I showed how differential computation can be a great fit for building graph processing systems that benefit from incrementally sharing computations.
