Rate My Professor Andrew Hogg

Professor Andrew Hogg is Professor of Fluid Mechanics in the School of Mathematics at the University of Bristol. He earned his M.A. and Ph.D. from the University of Cambridge, completing his Ph.D. in 1995 at the Department of Applied Mathematics and Theoretical Physics under the supervision of Professor H.E. Huppert FRS. His early career included a position at the Overseas Development Unit, HR Wallingford from 1990 to 1991, followed by a Research Assistant role at DAMTP, University of Cambridge from 1995 to 1997, funded by the Ministry of Agriculture, Fisheries and Food. In 1997, he served as Director of Studies at Christ's College, Cambridge. At the University of Bristol, he progressed from University Lecturer (1998-2003) to Senior University Lecturer (2003-2008), Reader in Applied Mathematics (2008-2015), and Professor of Fluid Mechanics since 2015.

Hogg's research centers on the dynamics of fluid motion applied to geophysical and environmental situations, with particular emphasis on two-phase flows, including sediment transport, gravity currents, turbidity flows, erosion, and avalanches of granular material. He develops mathematical models capturing the fundamental dynamics of these flows, which are validated against experimental measurements and field observations. As part of the Applied Mathematics and Numerical Analysis Group and the Centre for Environmental and Geophysical Flows, his work contributes to interdisciplinary efforts involving mathematicians, earth scientists, engineers, and geographers. Key publications include 'Key future directions for research on turbidity currents and their deposits' (2015), 'Interaction between volcanic plumes and wind during the 2010 Eyjafjallajökull eruption, Iceland' (2013), 'The effects of hydraulic resistance on dam-break and other shallow inertial flows' (2004), and recent papers such as 'Gravity current escape from a topographic depression' (2024), 'Lava delta formation: mathematical modeling and laboratory experiments' (2024), 'Flow of a viscoplastic fluid around a particle' (2025), and 'Viscoplastic slumps supported by a barrier' (2025). These contributions advance modeling of complex flows relevant to natural hazards.
