Qualifications:
PhD BioSciences (Nottingham, UK), MSc Horticulture (West Virginia, USA), BSc Hons Horticulture (Bath, UK)

Field of specialisation:
Physiology, growth and development of food crops with special emphasis on water/drought stress.

Research interests: Flavour volatile compounds of truffles (Kalaharituber pfeilli Trappe). Postgraduate students research is on various plant/crop science fields such as effect of temperature regimes on aging of potato (Solanum tuberosum) and water deficit in sweet potato (Ipomea batatas), integrated pest management system (IPMS), refugia configurations in GM maize (Zea mays) and use of biological control agent formulations.

Research Projects:

  • Investigation of volatile components of the Kalaharituber pfeilli (Trappe) using GCXGC-TOFMS
