About Me

I am a professor in the Information Security Group at Royal Holloway, University of London. Previously, I was a postdoc in the same group working on multilinear maps, a postdoc at DTU in Copenhagen, Denmark and a postdoc in the POLSYS team of LIP6 at Université Pierre et Marie Curie (UPMC) in Paris. I earned my PhD in the Information Security Group at Royal Holloway, University of London under the supervision of Carlos Cid. Before, I studied computer science at Universität Bremen where I wrote my Diplomarbeit in the AℓZAGK group under the supervision of Michael Hortmann.

Academic Interests

My (current) main academic interests are:

  • lattice-based cryptography
  • applications of computational mathematics in cryptography
  • real world cryptography and applications
  • computational mathematics in general
  • symmetric key cryptography and cryptanalysis: block ciphers mainly
  • efficient linear algebra (over small finite fields)

Computation

I’m a maintainer for fplll and fpylll. I’m also a developer for the Sage mathematics software, the maintainer of the M4RI library for fast linear algebra over and the M4RIE library for fast linear algebra over .

Open Source

I make all my code publicly available, this includes the research code used in publications as well as LaTeX sources for papers and slides. I encourage you to do the same.
