I'm a Senior Lecturer at the University of Glasgow and a member of the Terrier Team. I did my PhD at Georgetown University under Nazli Goharian and Ophir Frieder, where I was a member of the IR Lab. My research focuses on applying machine learning to problems in IR and NLP. I received the ACM SIGIR Early Career Researcher Award, the AI2 Intern of the Year Award, the ARCS Endowment Fellowship, and paper awards at SIGIR, ECIR, and COLING. Before graduate school, I worked as a software developer at IIT/SourceTech.
I am currently looking for PhD students. Please contact me if interested. PhD projects that cover topics such as learned sparse retrieval, adaptive retrieval, and retrieval-augmented generation are especially encouraged.
