Hello👋, welcome to my personal website! I am a PhD student majoring in computer science student, my research interest lies in security of agentic AI systems: prompt- and skill-level backdoors, and the limits of static auditing for LLM agents. Related interests in machine learning privacy (membership inference) and machine unlearning. You can find more about my background in my CV.

Membership Inference Attack with Cumulative Topological Distance

Introduction As machine learning models become increasingly powerful and pervasive, concerns about privacy in their deployment have grown. One notable risk comes from membership inference attacks, where an adversary attempts to determine whether a particular data point was used to train a given model. For example, in healthcare, a membership inference attack could reveal if someone participated in a clinical study, threatening patient confidentiality. This risk motivates my work in this post, where I document my recent experiment investigating the possibility in using cumulative topological distance in membership inference attacks. ...
