1982 - 1990 Rothamsted Experimental Station: Senior Scientific Officer.
I developed programmes researching the structure and function of cereal proteins, particularly in relation to bread making quality in wheat and malting quality in barley. I developed an interest in oilseed crops in relation to oil quality and the storage of oil in oil bodies. I carried out collaborative work with other UK research institutes and universities and internationally on aspects of cereal chemistry, notably INRA (France) and CSIRO (Australia). I worked with industry as a consultant and on industrially funded projects.
1990 - 2002 Long Ashton Research Station/University of Bristol: Principal Scientific Officer/Senior Research Fellow.
I was seconded to the University of Bristol and developed collaborative work with the Departments of Physics, Chemistry and Medicine. I developed an interest in cereal related diseases, bakers’ asthma and coeliac disease and have collaborated both nationally and internationally. In Physics I collaborated with a group using atomic force microscopies to probe the molecular structures of cereal proteins, starch and oil bodies. I have supervised a number of PhD students.
2003 - 2005 DSTL Porton Down: Team Leader Biomedical Countermeasures to Biological Threats.
2005- Cardiff Metropolitan University: Professor in Food Science and Nutrition.
I contribute to teaching in food chemistry and biochemistry, processing technologies, biotechnology, food raw material quality and research methods. My research is mainly concerned with coeliac disease and aspects of cereal and oil seed chemistry. I work closely with the ZERO2FIVE FIC providing expertise in the area of cereals, oils and oil seeds, coeliac disease and food allergy, hydrocolloids and general food chemistry issues.
