Research Interests/Areas of expertise

  • All aspects of seed health including Method development of seed health tests including development of quantitative real-time PCR assays for seed- borne pathogens.
  • Testing for Mycotoxins on cereal seed and identification of causal Fusarium species.

Biography

  • I trained as a seed analyst while employed at Scottish Agricultural Industries (SAI).
  • I joined SASA in1991 as a seed analyst in the Official Seed testing Station (OSTS). I obtained a BSc (hons) in Life Sciences. I moved on to become a seed technologist in the OSTS conducting research and development in seed health and in 2009 became the Seed Pathologist for the OSTS.
