Bio
I am a third year Computer Science PhD student in the Information Security Group at UCL (University College London). Researching Cryptocurrencies and Underground Markets under the supervision of Dr Sarah Meiklejohn (in the past with Professor Jens Groth), supported by the EU 2020 project. I am also apart of the Initiative for Cryptocurrencies and Contracts (IC3).
My history is as follows, I completed a Masters of Philosophy (MPhil) in Advanced Computer Science at the University of Cambridge under supervision of Dr Richard Clayton. My project was on “Discerning Patterns in the Compromise of Websites”. I completed an undergraduate degree in Computer Science with Industrial Expereince at Queen Mary, University of London. With my thesis under the supervision of Dr Paulo Oliva.
For my industrial year I worked as a full time technical analyst at Goldman Sachs.
