Dr Jeroen Dewulf is a full Professor in Veterinary Epidemiology at the Faculty of Veterinary Medicine of Ghent University. His main research interests are quantitative epidemiology and control of zoonoses with a specific emphasis on antimicrobial use and resistance in animals as well as the prevention of epidemic and endemic diseases with a focus on the application of biosecurity measures. He is the head of the Veterinary Epidemiology Unit and is supervising over 10 Ph.D. students who are doing research in the field of veterinary epidemiology. He is (co-)author of over 300 A1 publications in the field of veterinary epidemiology with an H-index of 45. He is the principal author of the annual Belgian report on Antimicrobial Consumption in Animals (BelVetSac) and chair of the JPI-AMR network on the quantification of antimicrobial consumption in animals at herd level. Since 2009 he is a member of the scientific committee of the Belgian federal food agency and is the founder and chair of the board of the center of expertise on antimicrobial use and resistance in animals (AMCRA) in Belgium. Dr Dominiek Maes is Professor of Porcine Health Management in the Faculty of Veterinary Medicine at Ghent University, Belgium.
