Stuart Littlefair

Professor Stuart Littlefair is a Professor of Astrophysics at the University of Sheffield's School of Mathematical and Physical Sciences. His research focuses on Interacting binary stars, Brown dwarfs and low-mass stars, Star formation, and High time resolution astrophysics. He contributes to projects like the Gravitational-wave Optical Transient Observer (GOTO), which detects transient astrophysical events. His work bridges observational astronomy and theoretical modeling, emphasizing multi-messenger astronomy and gravitational wave source identification.

Research interests include studying accretion processes in compact binaries, AGN variability, and transient phenomena like gamma-ray bursts. Recent publications highlight his involvement in analyzing high-cadence optical/X-ray data (e.g., NGC 4395 AGN variability studies) and discovering peculiar systems such as inflated brown dwarfs in eclipsing binaries. He collaborates internationally, serving on committees like the ESO Observing Programmes Committee and the LSST:UK Board.

Teaching activities include PHY241 Observational Astronomy. Professional roles include leading the Astrophysics Research Cluster and contributing to departmental administration (e.g., Head of Second Year Astrophysics). His work supports the University of Sheffield's astronomy infrastructure, including the GOTO telescope array.
