Dr Paul Humphreys

Applied Sciences

Biography

I am a practical microbiologist with over 15 years experience of working in applied microbiology. Most of my professional life has been in industry where I ran a range of larger scale research project including working for the EU and the UN. I am currently lecturing in food and medical microbiology, bioremediation, infection control at Huddersfield University.

My current interests include the development and testing of biocidal products for the medical, industrial and domestic markets which includes woking with MRSA, C. difficile, Listeria, Campylobacter etc. I also have research interests in microbial air contamination, waste degradation, pollution control and biofuels.

Research & Scholarship

I have a range of research interests in applied and environmental microbiology. These include: Development and testing of bactericidal, sporicidal and fungicidal products for medical, industrial and domestic markets Anaerobic degradation of pollutants and polymers and currently have research ongoing on anaerobic cellulolytic fungi and the degradation of amide wastes. Fate and transport of metal pollutants through the biosphere and the role of microbes in facilitating and attenuating this transport. Contaminated land remediation including phytoremediation.

Areas for Research Supervision

Anaerobic Degradation of cellulose and other polymeric organic materials

The degradation of polymeric materials is an important aspect of anaerobic microbiology since it contributes to biogas generation, animal nutrition and the environmental fate of man made materials. I currently have a number of ongoing research projects investigating the anaerobic degradation of cellulose and plastic additives and expect to continue to carry out research in these areas.

Development and testing of biocidal products

The development of novel biocidal products aimed at emerging infections and spore forming bacteria such as C. difficile are of particular interest to my research group.

Degradation of Radioactive Wastes

Many radioactive wastes are amenable to microbial degradation. This degradation is often associated with gas generation and the production of metabolites which may influence radionuclide mobility. The modelling and investigation of the degradation of organic radioactive wastes is an area of active research.
