I am currently Chancellor's Fellow / Associate Professor within the Departement of Computer and Information Sciences at the University of Strathclyde, where I lead the Interactive Information Retrieval group. I work on:
- modeling information access and retrieval problems to understand how and why people search for information,
- developing formal models to improve information access systems,
- and study how such information systems shape and influence our lives.
This brings in a wide range of research including theoretical research on the design and modeling of information access systems, empirical lab-based research, simulation of user interaction and the development of suitable methods for evaluating information access and retrieval systems.
Currently, I am particularly interested in describing, predicting and explaining the interaction between users and systems using theory from economics and cognitive science. Often this requires large-scale simulations of the interactions between users and systems and the mining of query and interactions logs to formulate statistical and functional relationships between interaction, performance and effort. Also, I am working towards relating how the cognitive load, physical effort, and temporal costs affect the interaction of users and the performance that they achieve through search systems.
