I'm a researcher at BU computer science focusing on privacy, with an affiliation in the Hariri Institute. I got my PhD from Johns Hopkins University in 2020, under the supervision of my advisors Avi Rubin and Matt Green.
If you came to this website expecting stuff about the placebo effect or alternative medicine, you may be looking for my father's website.
My group at JHU recently set up a website to help keep track of all the exciting new publications in applied crypto researching. While EPrint is great and all, its hard to read 1500 publications a year, especially when very few of them are applied. We call it Applied Cryptography Research: A Board aka ACRAB. Check it out!
