I am Professor in Food Safety and Global Health. I am interested in assessing the impact of food chemical contaminants (specifically mycotoxins) on human health, and developing effective intervention to protect public health from these toxic chemicals.

My training background is in the field of Medicine and Public Health. Aflter obtaining a PhD in food toxicology, I worked in the School of Medicine in Leeds as an Reserach Fellow since 2000.  I was a Visiting Scientist in the International Agency for Research on Cancer (IARC) during Jan-May 2013. Between 2013-2016, I worked in the Queen's University of Belfast as a Reader on nature toxins epidemiology. I returned to Leeds in the School of Food Science and Nutrition from 2016 to continue my research on mycotoxins and human health. 

I have served as a working group member for international agents including the IARC, the European Food Safety Authority (EFSA).

As a passionate and experienced research on global health, I have led a number of international collaborative research projects studying exposure to food mycotoxins and child health. These work demonstrated the toxins detrimental effect on child nutrition and health, providing scientific evidence for policy decision on mycotoxin reduction and control in Africa and China. My research has been generously funded by the Royal Society UK, The BBSRC, The National Institute of Environment Health Sciences (NIEHS) USA, and charities including The Bill and Melina Gates Fundation, the Wellcome Trust and the Sir Halley Stewart Trust. In the past 20 years' research, I have established a strong research network with scientrists worldwide including the Tanzania TFDA, The South Africa MRC, the Gambia MRC, London School of Hygiene and Tropical Medicine (LSHTM), the IARC and the China CFSA.


  • School International Lead

Research interests

  • Exposure biomarkers to assess dietary exposure to food born natural toxins such as mycotoxins.
  • Epidemiology studies to investigate the impact of exposure to mycotoxins on human health, in high risk regions (e.g. sub-Sahara Africa) with a focus on cancer, child malnutrition, and reproductive function.
  • Laboratory in vitro study to understand the mechanism of mycotoxins on human health.
  • Evaluate interventions to mitigate mycotoxins, using sustainable methods such as post-harvest storage improvement and public education.
  • Dietary exposure and cancer.
