Mark Simkin

I am a cryptography researcher at the Ethereum Foundation. I received my PhD in October 2019 at Aarhus University, where I was advised by Ivan Damgård and co-advised by Claudio Orlandi. After my PhD, I had the pleasure to be a postdoctoral researcher under the supervision of Kasper Green Larsen at Aarhus University.
