Security Researcher • PhD Candidate • University of Wisconsin-Madison

I am currently a Ph.D. student in the Computer Science Department at University of Wisconsin-Madison. Since 2019, I have been a member of Security and Privacy Research Group (MadS&P), where I am co-advised by Prof. Earlence Fernandes and Prof. Rahul Chatterjee.

My research interests broadly lie in system security, authorization, and applied cryptography. My current works focus on the security and privacy issues in online systems that integrate with various third-party services, such as trigger-action based automation platforms and business collaboration platforms.

Prior to my graduate school journey, I obtained my Bachelor’s degree dual majoring in Computer Science and Computer Systems Engineering (summa cum laude) from Rensselaer Polytechnic Institute.
