Professor David Alexander is a distinguished academic at Durham University's Department of Physics, where he serves as Professor and Chair of Board of Examiners. His responsibilities include Head of Section for Astronomy and Director of Postgraduate Research, demonstrating his significant leadership role within the department. Alexander is also responsible for teaching the Stars Lecturer component of the Level 2 Stars and Galaxies course.
His primary research interests focus on Active Galactic Nuclei, black holes, and galaxy formation and evolution, representing core areas in modern astrophysics. Alexander's work spans observational and theoretical aspects of high-energy astrophysics, with particular emphasis on understanding the connections between supermassive black holes and their host galaxies across cosmic time. His research leverages data from major international facilities including NuSTAR, ALMA, DESI, and XMM-Newton, conducting multi-wavelength studies that combine X-ray, infrared, optical, and radio observations.
Analysis of his most recent publications reveals a strong focus on AGN demographics, obscuration mechanisms, quasar environments, and the role of AGN in galaxy evolution. His work frequently explores the connection between AGN activity and galaxy properties, with particular attention to the cosmic evolution of these relationships. Recent papers demonstrate increasing emphasis on large-scale surveys and statistical approaches to understanding AGN populations.

Professor Alexander has been instrumental in numerous major survey projects including the NuSTAR extragalactic surveys, DESI quasar studies, and the VST ATLAS Quasar Survey. His collaborative work spans international teams and leverages cutting-edge observational facilities across the electromagnetic spectrum. His research group focuses on understanding the physical processes that govern AGN activity and their connection to galaxy evolution, with particular emphasis on obscured AGN populations and their role in the cosmic black hole growth history.
