Current Projects: I research on scheduling of differential privacy budget. Our paper on this topic was accepted to OSDI ‘21. I also research on mapping Internet traffic and user activity.
Biosketch: I am an incoming PhD student at University of Pennsylvania. Prior to UPenn, I was a Master’s student at Columbia University, advised by Asaf Cidon. I also work closely with Roxana Geambasu, Ethan Katz-Bassett, Ryan Stutsman and Mathias Lécuyer. Previously, from 2015-2019, I worked in the financial sector, developing quantitative algorithms and systems for investment. Before that I received a Bachelor’s degree in Financial Mathematics from Southern University of Science and Technology in 2015.
Interests: I am passionate about improving security, performance and reliability in systems and networking. I appreciate work.

For workloads operating on sensitive user data, privacy loss should be carefully orchestrated to enforce a global bound on personal data leakage. This paper presented PrivateKube, an extension to the Kubernetes workload orchestrator that adds differential privacy budget as a new native resource to be managed alongside traditional compute resources. PrivateKube incorporates a novel scheduling algorithm, DPF, the first one suitable for the unique characteristics of the privacy resource, including its all-or-nothing utility and non-replenishable nature. We show that DPF has desirable theoretical properties, outperforms baseline scheduling algorithms, and that native integration of privacy into Kubernetes can facilitate reuse of existing tools to better manage this scarce resource.
