Phil addresses big environmental questions using the ecology and chemistry of microscopic organisms.  His focus is on using diatoms and stable isotope methods to explore changes in climate, biogeochemical cycling and water quality changes.

He has spent much of the last 25 years working in Africa investigating long term climate change from lake sediment archives.  Parallel studies have been conducted in the Lake District examining water quality and ecological changes in lakes and rivers.

Published Research

Phil has published more than 100 papers and book chapters including six in Nature and Science.

His most recent work explores the long term evolution of climate on Kilimanjaro using oxygen, silicon and carbon isotopes from the remains of diatoms in the sediments of Lake Challa, a 97m deep volcanic crater.  He is also investigating changes in the carbon cycle of freshwater ecosystems using carbon isotopes from contemporary biofilms in lakes and rivers.

Phil has received funding for his work from:

• Natural Environmental Research Council (NERC)
• Engineering and Physical Sciences research Council (EPSRC)
• International Continental Scientific Drilling Program (ICDP)
• Department for Environment, Food and Rural Affairs (Defra)

Current research

Phil’s current research projects include:

• A Defra-funded project aiming to mitigate the effects of diffuse pollution from farms
• ICDP funded project to drill Lake Challa, Kilimanjaro

He co-leads the Eden Demonstration test catchment with particular responsibility for biomonitoring

Phil’s PhD students are using diatoms and isotope methods in biomonitoring and studies of environmental change.  Current projects include: land use and climate variability in the Lake District; biomonitoring of UK rivers; climate change from Iberian speleothem; and carbon release from Icelandic glaciers.

Roles

Phil is currently:

• Director of Lancaster Environment Centre
• Visiting Researcher at the British Geological Survey
• Convenor of the Isotopes and biogenic silica (IBiS) working group
  • Convenor of UK’s contribution to the International Continental scientific Drilling Program
  • Member of the NERC peer review college
  • Editorial board member of the Journal of Quaternary Science

Teaching

Phil’s current teaching roles include:

• Lecturing on various aspects of environmental change to BSc Geography, Physical geography, Environmental Science, Earth Science and Ecology students
• Leading a field course to Northern Spain
• Leading a masters module on Lake Ecology in collaboration with the Centre for Ecology and Hydrology
• Acting as an external examiner and assessor of undergraduate schemes at other major UK universities

He has examined more than 25 PhD students from different UK and international universities.
