Short Bio

Since August 2015, I have been a faculty in the Department of Mathematics & Statistics at the University of South Florida (2015-20: Assistant Professor, 2020-pres: Associate Professor). I am also the director of the USF Center for Cryptographic Research and a courtesy faculty in the Department of Computer Science & Engineering. I am an associate editor of the International Journal of Computer Mathematics: Computer Systems Theory.

For 1 year, I was a postoctoral fellow at the University of Waterloo under the supervision of Michele Mosca and David Jao . I was supported by the Cryptoworks21 program and the Institute for quantum computing .

For 2.5 years, I was a postdoctoral fellow at the University of Calgary under the supervision of Michael Jacobson Jr. I was supported by a PIMS fellowship.

For 6 months, I was a visiting scholar in the MAGMA development team at the University of Sydney, invited by John Cannon and Claus Fieker.

I received a PhD from the cole Polytechnique under the supervision of Andreas Enge.
