Dirk is a Professor of Veterinary Epidemiology, and Head of the Veterinary Epidemiology and Public Health Group in the Department of Veterinary Clinical Sciences. He is currently working on several projects covering animal diseases such as avian influenza, African swine fever and Methicillin-resistant Staphylococcus aureus in companion animals. He is also a Co-Course Director of the MSc Veterinary Epidemiology and MSc Veterinary Epidemiology & Public Health by Distance Learning. Dirk holds an Honorary Professorship at the London School of Hygiene and Tropical Medicine.
Biography
Dirk graduated from Justus Liebig University, Giessen, Germany in 1984 with a Degree in Veterinary Medicine. He went on to complete a Doctorate of Veterinary Medicine at the same university in 1986. Following this Dirk went on to do a Postgraduate Diploma in Tropical Veterinary Medicine at the Free University of Berlin, which involved fieldwork in Kenya, Somalia, Malaysia and Thailand.
In 1987 Dirk moved to Massey University, New Zealand to complete a PhD in veterinary epidemiology and remained there for 11 years, where he became a Lecturer in Production Medicine and Epidemiology in 1992 and was promoted to Senior Lecturer in Veterinary Epidemiology in 1996. Dirk joined the Royal Veterinary College in 1999 as a Professor in Veterinary Epidemiology. Dirk is also an Honorary Professor at the London School of Hygeine & Tropical Medicine.
Membership of Advisory Committees and Expert Panels: European Commission's DG SANCO Surveillance Task Force (since 2009); Editorial Board of the international scientific journal The Veterinary Journal (since 2002); Editorial Board of the international scientific journal BMC Veterinary Research (since 2005); International Advisory Committee for Review of Food Safety and Biosecurity Programmes of Singapore's Agri-food and Veterinary Authority (since 2002); Scientific Panel for Animal Health and Welfare of European Food Safety Authority (2003-2009); International Advisory Standing Committee of Australian Biosecurity Cooperative Research Centre (since 2005); Wellcome Trust’s funding committee ‘Tropical and Clinical Immunology and Infectious Disease’ (2005-2008)
Research
Dirk’s research has been widespread and varied, but with a special emphasis on evidence-based veterinary medicine, analytical epidemiology, advanced multivariate techniques, spatial and temporal analysis of epidemiological data, development of animal health information systems, computer modelling of animal disease, and field ecological research methods.
Current funding as principal investigator: approximately £2.2Mill for research programme on African swine fever virus funded by the Wellcome Trust; £600,000 for animal welfare research from BBSRC; £150,000 from DEFRA for investigating the epidemiology of MRSA in dogs and cats; plus another £100,000 for various smaller research projects; £1.4Mill from DEFRA for investigating bio-security in beef cattle in the U.K; £300,000 from DFID for research into Avian Influenza in Africa and Asia; Euro 1 Mill. from Pfizer Ltd for investigating the epidemiology of bovine pancytopenia.
Past funding: approximately £2.3Mill research funding for various projects, including use of biomarkers to predict horse fractures, antibiotic usage in pig production, development of a global animal and production atlas, development of predictive spatial risk models for rift-valley fever in Africa, control of tick-borne diseases in redline zone of Kruger National Park, role of wildlife in the epidemiology of paratuberculosis, spatial patterns of avian influenza in China, tuberculosis in wild possums in New Zealand.

Teaching
Dirk teaches Epidemiology mainly at postgraduate level, including teaching of specialist courses at advanced level. Dirk is currently the Director of the Masters Course in Veterinary Epidemiology, and the Distance Learning MSc course in Veterinary Epidemiology and Public Health. Dirk has also designed and taught international training courses in veterinary epidemiology, risk analysis and spatial analysis in Austria, Australia, Canada, China, Croatia, Denmark, Ethiopia, Germany, New Zealand, Malawi, Mongolia, Singapore, Sweden, Switzerland, Thailand, Vietnam and United Kingdom.
