Daniel Collins' Website

About Me:

I am a PhD Student at EPFL, Switzerland under the supervision of Serge Vaudenay working in cryptography; I have been working at EPFL since September, 2019.
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.
So far, I work on or have worked on the following topics:

I am expecting to graduate in early 2024 and start a postdoc in June. Please feel free to get in touch about work opportunities or if you would like to collaborate.
