Curriculum Vitae

About Me: I am a PhD candidate in the area of cryptography, working under the supervision of Dr Sarah Meiklejohn and Dr Jens Groth. Microsoft Research is supporting my PhD and I am being co-supervised by Dr Markulf Kohlweiss. I will spend this summer interning with at Microsoft Research with Dr Markulf Kohlweiss. I have been studying as part of the Information Security Group at UCL since November 2015. Before joining UCL I studied for an MSci degree in Mathematics at the University of Bristol. My dissertation was on representations and special functions and was supervised by Dr Yves Tourigny.

Research Interests: I am interested in the formal design and analysis of cryptographic protocols. In particular, I have recently been looking into different types of signature schemes and how they can be used in blockchain technologies.

Teaching: I helped teach the Cryptanalysis course in 2017. My main role was to supervise students in thier attempt to find trapdoor-ed primes on the internet. I also gave an introductory lecture on the use of zero-knowledge proofs in cryptocurrencies. See here for slides.
