I am an Engineer at Bloomberg LP and a 4th year PhD Candidate at the University of Glasgow working within the IR group. I am supervised by Dr Debasis Ganguly and Dr Sean MacAvaney. My work is currently supported by the Bloomberg PhD Data Science Fellowship. My research interests are primarily in Information Retrieval. Before my PhD I completed my honours degree in Computer Science at Glasgow.

My thesis is focused on the structure of ad-hoc ranking systems and how we can incorporate broader features in semantic interactions. A relatively up to date CV can be found here. Reach out on Twitter or by email if you want to chat about research or code. I’m generally interested in collaborations centred around modern IR evaluation and anything neural IR.
