About Me
My primary research spans differential privacy and machine unlearning.
I am also excited about theory-driven continual and sequential learning.
I am working under the guidance of Mark Bun in the Theoretical Computer Science research group.

Projects (listed)
Privacy Preserving Machine Learning| Differential Privacy, Learning Theory
-
The broadest goal is to better understand the divide between traditional and private approaches in interpretable decision-making and convert private learning algorithms from the batch setting to the online setting.
-
Developed near-optimal differentially private learning algorithms in the batch (PAC) and online settings for foundational concept classes such as generalized decision lists, sparse disjunctions, and large-margin halfspaces.
Responsible & Safe AI | Machine Unlearning, Computer Vision, XAI
-
Developed a dual-objective approximate machine unlearning algorithm for Image classification (NeurIPS 2023 Machine Unlearning Challenge).
-
Experimented with other unlearning methods (i.e. SCalable Remembering and Unlearning unBound (SCRUB), teacher-student, negative gradient descent, and variants with relative entropy regularization) on CIFAR-10.
