Education:
BSc Cell Biology (Hons) - University of Newcastle upon Tyne 1986 DPhil - University of York 1991 I obtained my degree in cell biology at the University of Newcastle upon Tyne in 1986 and went on to complete a DPhil in chemical carcinogenesis at the University of York in 1991. I completed postdoctoral fellowships at the NCI Frederick Cancer Research & Development Center in Frederick, Maryland, the University of York and the University of Leicester. Professional Experience: I was appointed as a Senior Lecturer in Applied Toxicology at De Montfort University, from 1998-2000. In 2000 I moved to the School of Medicine at Leeds as a Lecturer in Molecular Epidemiology. I was appointed Associate Professor in 2013 and now focus on mycotoxin research (exposure and health effects, especially for aflatoxin in Africa) and toxicity of urban particulate matter. I am also lead in several student education areas for the School and University. Scientific Research Field: 1. Areas of expertise My areas of expertise include environmental toxicology; biomarkers of exposure; aflatoxin exposure and health; mycotoxins; nanoparticle toxicity; air pollution particulate toxicity. 2. Research interests Mycotoxins are produced by fungi that grow on food crops. Although they occur around the globe, the most toxic, such as aflatoxin, are a major health concern in warm humid countries such as in sub-Saharan Africa and South East Asia. In the cross-faculty Mycotoxin Research Group, we use laboratory analytical methods to measure biomarkers of mycotoxin exposure in blood or urine from exposed populations, and epidemiological methods to assess the health impact of this exposure.
Social academic post and honor: We have worked closely with colleagues in Tanzania and the Gambia to study health impacts on children. One of these impacts is on impairment of child growth: https://doi.org/10.1186/s12889-018-6164-4. I have also worked on the toxicity of urban particulate matter for several years. Ultrafine particles such as those present in traffic exhaust emissions contribute greatly to the toxic effects of air pollution. They can induce DNA damage, a first step in carcinogenesis. Recently we have investigated the impact of particulates on blood clotting, as a possible mechanism by which particles can induce cardiovascular events such as heart attack.

I am involved in teaching medical courses related to my expertise (environmental toxicology; biomarkers of exposure; aflatoxin exposure and health; mycotoxins; nanoparticle toxicity; air pollution particulate toxicity).

Main Scientific Research Projects: Aflatoxin exposure and associated immune function damage in young children (ongoing): Goal: This project examines the mechanisms through which aflatoxin exposure cause immune system dysregulation in young children using human epidemiological studies and in vitro bioassays. Biomarker diagnosis of a recent aflatoxicosis outbreak in Tanzania (archived): Goal: Our research Lab was involved in analysing blood samples collected by World Health Organisation (WHO) for aflatoxin-albumin adduct biomarker during the aflatoxicosis outbreak in Tanzania in 2016. During this outbreak, at least 14 deaths linked to the Dodoma and Manyara incidents were recorded while there were 53 suspected cases. Evaluation of Dietary Exposure to Mycotoxins in Young Children (archived): Goal: This project evaluated the contribution of mycotoxins to child health burden in Tanzania. Assessing health burdens of aflatoxin in Tanzania and developing models to predict aflatoxin risk - capacity building and pump priming research (ongoing): Goal: The proposed pump-priming research is anticipated to provide a research framework and methodology to the GCRF-AFRICAP project. The project will estimate health risk by investigating aflatoxin in food and exposure biomarkers in Tanzanian children utilising an established cohort, and calculate the expected health burden using the Disability Adjusted Life Years (DALYs) according to the WHO food-borne disease burden estimate method. Mycotoxins as a Risk Factor in Childhood Growth Impairment Worldwide (ongoing): The project is geared towards understanding the mechanistic pathways through which mycotoxins contribute to child growth impairment. Patents: Scientific Research Achievements and Awards: Our work has made an impact on awareness and policy-making in sub-Saharan Africa, through collaboration with the East Africa Community and the Partnership for Aflatoxin Control in Africa. https://aflasafe.com/wp-content/uploads/pdf/TPP-2-Aflatoxin-and-the-1,000-Days.pdf https://aflasafe.com/wp-content/uploads/pdf/TPP-8-Aflatoxin-Standards-for-Food.pdf https://resources.selerant.com/food-regulatory-news/blog/east-african-food-standards-2015 http://www.aflatoxinpartnership.org Number of postgraduates under supervision: Number of supervised masters and Ph.D. Number of supervised undergraduates The above information updated Sep. 2019 |
