Dr Graham Bradley

Associate Professor (Senior Lecturer) in Microbiology

School of Biomedical and Biological Sciences (Faculty of Science and Technology)

Role

Deputy Head of School.

I have a broad interest in understanding the many aspects of environmental microbiology, which include the interrelated activities of protistans, fungi, the prokaryotes and viruses. In the past I have been involved in research into biodeterioration, biodegradation, microbial biofilms and especially biochemical aspects of microbial metal corrosion. We currently form a small team of academic and technical staff working on several projects but with a special interest in the development of the modern molecular methods that have really revolutionized microbial ecology.

Senior research technician, Pharmacology, Wellcome Research Laboratories, (1980-81)

Graduate Member of the Institute of Biology, Polytechnic of the South Bank, (1980)

Research technician, Dept.of Biochemistry, Chelsea College, University of London, (1974-80)

Professional membership

• Member of the Society of Biology.

• Member of the British Mycological Society.

• Member of the Society for Applied Microbiology.

Roles on external bodies

Editorial board member (2001-2007) The World Journal of Microbiology and Biotechnology, Kluwer academic publishers.

Teaching interests

Fellow of the Higher Education Academy

I have an active interest in the research and use of novel teaching and assessment methods within my subject area. I am especially interested in problems of the delivery of advanced molecular microbiological techniques to larger student groups.

Staff serving as external examiners

External examiner (1999-2004), Edexcel HNC/D Applied Biology, School of Pharmacy & Biomolecular Sciences, University of Brighton.

Research interests

• The development of novel and rapid indicators of human pathogens in marine bathing waters and "out of season" risks to surfers and bathers. This has led to studies on the faecal bacterium Bacteroides fragilis and its bacteriophages.

• The modification and control of marine and freshwater biofilms: including water delivery systems.

• The microbial skin and gut flora of fishes, especially in response to pre- and probiotic feeds and spoilage situations.

Research groups

  • Food, Nutrition and Health
