Summary:

I developed a passion for microbiology, during my doctoral research at the University of Huddersfield. I developed laboratory protocols to cultivate and enumerate the coliphage MS2, the bacteriophage of Enterobacter cloacae and multiple antibiotic resistant endospores of bacillus subtilis var. niger (B. globigii). I then used these biological tracers in multiple tracer experiments to determine the retention time of microbial pollutants, measured as Faecal Indicator Organisms (FIOs), in constructed wetlands fitted as tertiary treatment on a sewage treatment works (Hodgson et al. 2002, 2003, 2004). Whilst at Huddersfield I went on to work on a European Craft funded project (QLK1-CT-2002-70806) to develop novel biocides and biocidal wipes, effectively developing methods to ?kill the little buggers? (the little buggers being microorganisms), (Hodgson et al., 2004, Schmalz et al. 2005). This work lead to a patent application for an Antimicrobial Construction, GB20040011304 20040521; WO2005GB01878 20050518. In June 2005 I moved to Devon and North Wyke Research, as a post doc on a Rural Economy and Land Use (RELU) project (RES-0224-25-0086), where I investigated the movement of FIOs from various farming systems within the Taw river catchment.

I have been instrumental in developing the microbiology laboratory here at North Wyke which formerly opened at the end of 2008. I am currently managing a DEFRA funded project (WQ 0118) Understanding the behaviour of pollutants through cracking clay soils

?In addition I am working on DEFRA funded project (WQ 0111) Faecal indicator organism losses from farming systems (FIO-FARM)
