About Me

Having begun my undergraduate studies at Leicester in 2008, I graduated in 2012 with an MComp in Computer Science.
I am now working under the supervision of Dr. Neil Walkinshaw and Prof. Rajeev Raman on my PhD: Boosting Automated Reasoning by Mining Existing Proofs.
My PhD studies are funded by a PhD studentship from the College of Science and Engineering PhD Studentship Scheme.

Research Interests

I am researching the topic of tactic mining for Interactive Theorem Provers (ITP's) in an attempt to provide better automation than is currently available. Users conduct proofs in ITP's by entering a finite sequence of proof steps - these can be thought of as functions that either solve a proof or advances the proof state in some way. What I am investigating is how we can apply machine learning techniques to libraries of these proof step sequences. If we can infer useful models from these examples, then hopefully we can use this newly learned information to automate the proofs of new conjectures. This method could be reasonabily applied to any ITP that uses tactics, and has a library of existing proofs that could be mined.

Away from the topics of my PhD, I am mostly interested in the theoretical side of Computer Science. Artificial Intelligence interests me a lot, and I was fortunate enough to be able to learn about computer chess for my 3rd year project. In addition to researching the key concepts, I implemented a chess game in Java, with my own GUI and game engine. If anyone is interested I can try and dig out my old code.

I am also interested in Formal Verification. For my masters dissertation, I used the SPIN model checker to verify some Service Oriented Computing protocols that were specified in a domain specific language. The main tasks were the representation of the models in PROMELA, and the formulation of the desired properties in Linear Temporal Logic.
