I am a postdoctoral fellow at Northeastern University, supervised by Alina Oprea. I obtained my PhD from University of Virginia, where I was extremely fortunate to be advised by Professor David Evans. I study the privacy and security challenges of machine learning models: both as targets of attacks and as amplifiers of risk. My work explores how models can be exploited and how they transform the security landscape of systems that use them, with recent emphasis on LLMs
