Alishah Chator

I am second year PhD student at Johns Hopkins University studying computer science. I am part of the Advanced Research in Cryptography group and advised by Professor Matthew Green. I am currently interested in applied cryptography and broadly on problems in computer security that impact technology policy. In particular, I seek to improve privacy by designing schemes with rigorously proven guarantees and auditing existing schemes to understand how privacy loss arises. Outside of my work at JHU, I have collaborated with Professor Narayanan's group in the CITP at Princeton University in blockchain analysis.

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
