Rob’s research covers multiphase, turbulent and stratified flows and is applied to offshore wind, via the Aura partnership project.

He has a PhD in mathematics from the University of Bristol, and has worked at the Parliamentary Office of Science and Technology, held two PDRAs at Southampton and Leeds and, since 2017, held a University Fellowship at Hull.

Rob leads international collaboration with Japan, hosting six visitors at Hull in 2018-19. He has contributed to >1.4m of research grants as primary- and co-investigator, published 24 peer-reviewed papers (H-index = 11) and was the recipient of a Gerhard Jirka Award, IAHR.

Teaching

Research PhDs

Rob welcomes applications from students interested in all areas of environmental and industrial fluid dynamics, in particular research relating to the fundamental mechanics of sediment transport and multiphase flow.

Current areas of interest include
  • direct numerical simulation of forced turbulence in stratified sediment-laden flows

  • integrated empirical measurements of flow velocity and suspended sediment concentration

  • impact of the built environment on stratified sediment-laden flow

  • suspension and transport of low density particles, from microplastics to flocs

  • lab-scale models of suspended sediment load dominated landscapes
