Professor Malcolm Bennett BVSc PhD MRCVS FRCPath FHEA

Malcolm Bennett is Professor of Zoonotic and Emerging Disease in the School of Veterinary Medicine and Science, Faculty of Medicine & Health Sciences, University of Nottingham. His areas of expertise include the ecology and evolution of infectious diseases, zoonotic transmission, emerging infectious diseases, and infectious diseases of wild animals. He is currently involved in projects on TB in badgers on the edge of the cattle epidemic and drivers of antimicrobial resistance (AMR) in wildlife populations and the environment, alongside rodent-borne zoonoses. He is also investigating a range of protozoal infections in wildlife and water - including cryptosporidia, Giardia and Acanthamoeba.

Professor Bennett is author or co-author of over 130 peer-reviewed papers, plus several books and book chapters, and is Principal Investigator or co-PI on external grants worth in excess of £20m. He is Chair of the Veterinary Products Committee (VPC) (member since 2012) and a former member (2011-2018) of the Advisory Committee on Dangerous Pathogens (ACDP), TSE Subcommittee and various Working Groups. Malcolm’s interests are in the ecology and transmission of infectious diseases, particularly those that cross species barriers, such as zoonotic infections, and new and emerging infectious diseases. Many of these diseases derive from wildlife and are best studied using ecosystems services/’One Health’ approaches; hence much of his research has been interdisciplinary - including working with behavioural and social scientists, including economists - cross-institutional, and often cross-sectoral, involving close cooperation with stakeholders.

Dr George Prpich BSc, PhD

I am an expert in environmental risk management, decision analysis, and environmental engineering. I study problems that span the water, energy, and food sectors and have published more than 35 peer reviewed articles and reports that describe my work in these areas. I am particularly interested in helping organisations to identify and prioritise their strategic risks, manage their uncertainties, and identify their emerging risks. I have advised and consulted for a number of international clients, such as the UK Government, the European Commission, and the United Nations. I hold a PhD in Chemical Engineering from Queen’s University, Canada.

Dr Mike Roberts BSc, MSc, PhD

Mike has Doctoral, Master and Bachelor degrees in environmental biology. He has over 20 years’ experience with the UK government’s Department for Environment, Food and Rural Affairs (Defra) in the sustainable management of chemicals, specifically with regard to potential endocrine disrupting chemicals (EDCs) and metals in the environment (especially mercury, lead and cadmium), chemical mixtures and possible interactions between the environment and human health.

From 2009 to 2016, Mike was one of the two UK National Co-ordinators on the OECD chemicals Test Guidelines programme and a member of the OECD’s Endocrine Disrupters Testing and Assessment Advisory Group (EDTA). He was instrumental in the development of several test guidelines and guidance documents for the detection of EDCs, for example utilising freshwater mollusc species and sticklebacks.

Mike was formerly a Visiting Fellow at Cranfield University and, in 2013, the Chair of the SETAC (Society for Environmental Toxicology and Chemistry) Global Partners Council. He was one of the two co-chairs for the SETAC Pellston Workshop™ Environmental Hazard and Risk Assessment Approaches for Endocrine-Active Substances (EHRA), held in early 2016 at Pensacola Beach, Florida, USA. The Workshop developed consensus-based advice on scientifically-defensible approaches for the environmental assessment of endocrine active substances.

Since leaving Defra and becoming an independent consultant in 2016, Mike has worked with colleagues on the assessment of chemicals as potential endocrine disruptors, utilising the OECD Guidance Document on Standardised Test Guidelines for Evaluating Chemicals for Endocrine Disruption.

Dr Paul Rumsby BSc, PhD

IEH Consulting Associate Director. Paul has been a toxicologist for 35 years and has a Bachelor of Technology degree in Applied Biochemistry and a PhD in biochemical pharmacology. He has been a European Registered Toxicologist since 1997. For 20 years, he was a laboratory scientist conducting cancer and toxicological research before undertaking desk-based toxicology. He has technical expertise on a range of toxicological mechanisms including mutagenesis, carcinogenesis, neurotoxicity and endocrine disruption. He has authored many scientific papers, reviews and client reports and presented at many national and international meetings.

Until recently, Paul was Principal Toxicologist and manager of the National Centre for Environment Toxicology, a group at WRc plc (formerly the Water Research Centre). He has undertaken many chemical risk assessments particularly on chemicals in the environment (air, soil and drinking and environmental waters) including incineration and landfill. This included the technical management of 24/7 advisory services for contamination of both drinking and environmental waters for the UK water industry and the Environment Agency. As such, he has expert knowledge of health-based screening levels (both short and long-term) for chemicals in water.

He has worked on projects for many UK government department and agencies and the EU including cancer risk estimates for ECHA and technical advice on Prior Informed Consent (PIC) as part of the UNEP Rotterdam Convention for the import and export of dangerous chemicals.
