My career has been spent entirely within academe. I have migrated from a purely engineering background to a field that is located at the intersection of biological and engineering disciplines.

Outline of main research interests:

My research is centred on microbial inactivation by methods that avoid the use of xenobiotic compounds. Such methods include UV irradiation and atmospheric gas plasma treatment, with applications ranging from reducing food wastage to improving safety.  My research covers a wide range of matrices including water and other liquids, air and the surfaces of solids.

A quite separate strand of my research interests covers the history of the development of antibiotics as chemotherapeutic agents.
