<!--[if gte mso 9]>

My research interests are in the applications of industrial microbiology and biotechnology. The first area is in the purification and characterisation of antimicrobial peptides from neutrophils, and investigation of the properties of bacteriocins from lactic acid bacteria, with the focus in the development of novel antimicrobials and biopreservatives. The second area is in the applications of biosensors in the early detection of food pathogens and biotoxins.
