Andrew J Hogg

Professor Andrew J Hogg is a faculty member at the School of Mathematics, University of Bristol. He is affiliated with the Cabot Institute for the Environment, specializing in fluid mechanics and applied mathematics. His research spans environmental phenomena, including volcanic ash clouds, debris flows, and sediment transport in coastal regions.

• Education: M.A., Ph.D.(Cantab.)

His research focuses on mathematical modeling of two-phase flows in natural environments. Key areas include:

• Volcanic ash dispersion and plume dynamics
• Granular segregation in industrial and geological settings
• Suspended sediment transport in rivers and coasts
• Viscoplastic material behavior in mudflows and debris flows

Recent work examines coherent turbulent eddies, yield stress transitions, and environmental impacts of engineering structures. Publications highlight interdisciplinary approaches combining analytical, numerical, and experimental methods.

Current projects address volcanic plume rise, viscoplastic slumps, and sediment transport models. He collaborates with earth science and engineering departments locally and internationally.
