Paul Turner Paul Turner, Assistant Professor MIAEH and Assistant Professor Epidemiology and Biostatistics
Room 2234J


(301) 405-6583

Dr Paul C Turner is a new tenure track faculty within the Maryland Institute for Applied and Environmental Health; having recently left the Molecular Epidemiology Unit, University of Leeds, UK. Dr Turner obtained his PhD in Chemistry at the University of Edinburgh, UK, and his undergraduate BSc with honors in Biochemistry and Toxicology at the University of Surrey, UK. He was also a visiting scientist at Johns Hopkins University in 2003 and 2005.

Dr Turner's research interests include understanding (1) the role of fungal toxins (mycotoxins) in chronic disease etiology, (2) establishing intervention strategies to restrict such exposures. Mycotoxins, which include the Aspergillus toxins aflatoxin and ochratoxin A, and the Fusarium toxins deoxynivalenol and fumonisin, contaminate up to 25% of the world's food supply. They are suspected agents in both acute and chronic disease. Aflatoxins are potent liver toxins and carcinogens, and are additionally suspected to cause growth faltering and immune-suppression. Four billion people are estimated to live in regions that are at risk of dietary exposure to aflatoxin. Fundamental research question include (a) understanding synergistic interactions between aflatoxin and hepatitis virus in liver cancer risk; (b) understanding the mechanism(s) of observational data on dose related aflatoxin growth faltering; (c) understanding the potential contribution that aflatoxin plays in early life morbidity and mortality in developing countries, including modulations in susceptibility to infections; (d) development and implementation of sustainable interventions to restrict exposure in the most vulnerable groups; (e) understanding of global climate change models and their impact on changing world patterns and levels of toxin exposure.

Fusarium mycotoxins have been implicated in esophageal cancer, though their potential role remains poorly explored. Deoxynivalenol, also known as vomitoxin, modulates the immune system and is associated with growth faltering in animals. Fumonsins have been linked to neural tube defects, and are a suspected co-risk factor in aflatoxin driven liver cancer. The recent development of an exposure biomarker for DON and a strong candidate for fumonisin provides the opportunity to better understand their potential role in human chronic disease, and better inform intervention strategies.
