Scientist, Crop and Food Research
August 2003-Jan 2004
Postdoctoral Fellow, National Centre for Advanced Bio-Protection Technologies
Research Officer, Lincoln University, research on Trichoderma biological control agents and writing grant proposals.
Postdoctoral Fellow, The Pennsylvania State University, systematics of fungi of the Hypocrea/Trichoderma genus complex.
Postdoctoral Fellow/Research Scientist, Lincoln University, research in developing molecular probes to track fungal biological control agents in the field and applying probes in field.
Quarantine Scientist, MAF Quality Management, monitoring of imported plant material for the presence of exotic pests and diseases, and surveys of crops for diseases currently present in NZ.
Teaching fellow/Research Assistant, University of Auckland, senior tutor for undergraduate microbiology laboratory course, research on biocontrol of plant diseases
Biodiversity studies Hypoctrea/Trichoderma species in NZ
Identifying and monitoring microbes throughout the composting process in the commercial mushroom industry
Identifying genes and environmental triggers associated with sporulation in the insect pathogenic fungus Beauveria bassiana
Developed a variety of DNA based molecular markers for monitoring fungal strains on plant material and in soil.
Employed these markers to monitor a fungal strain on kiwifruit leaves, flowers and fruit over a growing season.
Assessed the usefulness of introduced molecular markers (GUS, hygromycin resistance) for monitoring the survival and spread of fungal biocontrol agents in soil.
Characterised and identified Trichoderma isolates using ITS rDNA sequence, SSCP and RAPD-PCR data.
Used DNA sequence, morphological and cultural characters to delimit species within the genus Trichoderma and link them to their Hypocrea teleomorphs.
Assessed the risk, both economic and biological, of specific quarantine plant pathogens if accidentally introduced into the country.
Conducted a survey of cereal pests and diseases present in NZ.
