Daniel Collins' Website

About Me:

I am a PhD Student at EPFL, Switzerland under the supervision of Serge Vaudenay.
Previously, I studied Mathematics and Computer Science at the University of Sydney, where I spent time under the supervision of Vincent Gramoli in distributed computing which culminated in an Honours thesis.
Currently, I am mostly working in secure messaging and ratcheting in both the two party and group settings. I am also interested in side channel attacks and countermeasures, among other topics in cryptography.
