Tim is a physical geographer with expertise in environmental hydrology, palaeolimnology, aquatic and peatland environments. He has published widely on pollution studies, water quality change, environmental restoration and the dynamics of peatland ecosystems.  Tim has been PI on major grants from bodies including NERC, DEFRA and the Environment Agency, and has produced over 80 reports for non-academic organisations. He currently teaches courses on 'Hydrology and Catchment Systems' and 'Environmental Restoration.'
