Personal profile

I studied for four years at Imperial College London and received an MSci in Mathematics with First Class (Honours), specialising in Number Theory and Algebra.
Since joining the CDT in September of 2016 I have studied lattice cryptography and in particular its cryptanalysis. In the taught year I studied, in depth, a class of algorithms known as lattice sieves and decided to continue this work into the Ph.D proper. As well as completing a paper estimating the security of all lattice based submissions to the NIST Post Quantum Cryptography standardisation procedure, I am currently working on amortising lattice sieves inside lattice reduction algorithms. These are the basis of most concrete cryptanalysis and an understanding of their complexity is crucial to determining security of lattice based schemes. This work came about after an invited visit to CWI Amsterdam. 
Outside of academia I take an active role in the department's ``Capture the Flag'' (competitive hacking) team and also enjoy theatre.
