Alishah Chator


I'm currently a postdoc at the Faculty of Computing and Data Sciences at BU, mentored by Mayank Varia. I am interested in applied cryptography and broadly on problems relating to privacy. In particular, I seek to improve everyday privacy by examining deployment challenges that arise in both theory and practice.

I received my PhD at Johns Hopkins University studying computer science. I was part of the Advanced Research in Cryptography group and was advised by Professor Matthew Green. Outside of my work at JHU, I had collaborated with Professor Narayanan's group in the CITP at Princeton University in blockchain analysis. A copy of my dissertation can be found here.

I was previously an undergraduate student at the University of Michigan studying Computer Science, Mathematics, and Physics. While there, I worked with Professor J. Alex Halderman, most recently aiding in the development of censys.io.
