I am a PhD student in Boston University's Computer Science Department and a member of the security research group BUSec. I am being advised by Sharon Goldberg. I have done research on novel attacks on hash functions, differential cryptanalysis, Intelligent Transit Systems and cache based side channel attacks. I broke SHA3 contestant Spectral Hash. My current focus is on the RPKI and Bitcoin. Prior to graduate school I worked as a software engineer at the Broad Institute where I wrote microbial bioinformatics annotation software. I've also worked as a software developer at two successful startups, Pubget and Jumptap. In my free time I write games, experiment with web application technology, and blog about security.
