I am a PhD student in Computer Science and Engineering at the University of Washington, advised by Yoshi Kohno.

I’m generally interested in the security and privacy-related needs and practices of vulnerable populations. In a paper that I presented in May 2018 at IEEE Security and Privacy (Oakland), we presented recommendations of how technology could better support recently resettled refugees. Previously, I did work at the intersection of machine learning and malware analysis.
