Dr Jonathan Bridge FRGS, FHEA

Course Leader, MSc Environmental


I am an environmental geoscientist, researching the ways in which human activity affects the physical environment and try to find solutions to the ways in which the physical environment affects human activity. I joined the Department of the Natural and Built Environment in January 2017 and I am currently course leader for MSc Environmental Management.


I graduated from University College London with an MSci in Planetary Sciences, before completing an MSc in Environmental Sciences at Birkbeck, University of London, and then a PhD in Environmental Engineering at The University of Sheffield.

After my PhD I worked in the Kroto Research Institute as a postdoctoral scientist and early-career research fellow, on projects related to risks to human health from environmental pathogens, weathering of minerals by plant-symbiont fungi, supraglacial weathering and environmental colloids and nanoparticles.

I joined the Centre for Engineering Sustainability at the University of Liverpool in 2012 as a Lecturer in Environmental Engineering, where much of my research was oriented around environmental radioactivity, further work on environmental nanoparticles, and catchment modelling.

Returning to Sheffield in 2017 as a Senior Lecturer in Physical Geography here at Sheffield Hallam, I have become increasingly involved in catchment hydrology and natural flood management, conducting field, modelling and citizen science with local partners. I progressed to Reader/Associate Professor in January 2020.


Department of the Natural and Built Environment

College of Social Sciences and Arts

I am a Fellow of the Higher Education Academy (FHEA) and have taught extensively at undergraduate and postgraduate level since 2012. My main areas of teaching are in water resources and natural hazards and in the supervision of dissertation and thesis research projects. As well as subject-specific knowledge, my goal in teaching is to develop strong applied skills in critical thinking, creative problem-solving and communication of ideas.

Professional Practice


My primary research expertise, originating in my PhD work, is in the transport and fate of contaminants and colloids in soils and porous media. Through my time at Liverpool (2012-17) this work focused on applications in the nuclear industry and in environmental radioactivity, in collaboration with National Nuclear Laboratories in the UK and with partners in the UK, Japan and Taiwan. Past collaborators in Liverpool include Dr Andrew Boston (Physics), Dr James Cooper and Prof Neil Macdonald (both Environmental Sciences).
At Sheffield Hallam, my interests have broadened to encompass field-based hydrology and increasingly hydro-sociology, working with Sheffield & Rotherham Wildlife Trust to monitor Natural Flood Management interventions in small catchments on the Eastern Pennines around Sheffield. This has led to a range of exciting new applied and interdisciplinary research avenues, including an AHRC-funded collaboration on art and co-design in landscape decision-making, with Dr Niamh Downing, Prof Harriet Tarlo (SHU) and a network of academics, community and professional partners.
I have a track-record of research activity across the environmental geosciences. My early postdoctoral work was in soil- and waterborne pathogens and human health (invited paper in Bulletin of the World Health Organization), numerical and agent-based simulation of soil biogeochemical processes, and colloid transport and fate in porous media (including collaboration with Dr Claire Corkhill, Immobilisation Science Lab, The University of Sheffield). I also have strong interests in catchment-scale water and contaminant dynamics, in particular in semi-arid catchments in the Middle East (Jordan) and in application to supraglacial and pro-glacial environments. I have a longstanding interest in glacier surface processes (collaboration with Dr Tris Irvine-Fynn, Aberystwyth), particularly in the dynamics of sediments, biocolloids and chemical fate and transport in the weathering crust of glaciers.
My most recent work has involved collaboration with a team of Syrian academics supported by the Council for At-Risk Academics (Cara), who have collected the first regional baseline soil survey in North-West Syria since before the start of the Civil War in 2011.
