Peter van Horne is a senior researcher at Wageningen Economic Research (WECR). WECR is part of Wageningen University and Research (WUR) in the Netherlands. He got his degree in farm economics at the Wageningen University in 1984. Since than he is working at the WUR. From 1987 till 2001 van Horne was stationed as a economist at the Centre for Poultry Research ‘het Spelderholt’ in Beekbergen. Later his office was moved to the city of Wageningen. Van Horne is full time occupied with poultry research projects for the national government, EU, European Parliament, international organisations and industry. Main topics the last years have been the economics of animal welfare, environmental protection, animal health and international competition. As all his research is dealing with economics and poultry his position can be summarized by ‘poultry economist’. Mr van Horne has a long standing experience with leading international projects related to the poultry sector. Besides EU countries these projects relate to Brazil, Argentina, Saudi Arabia and Indonesia. Recently his focus is on projects in Africa to improve efficiency within the poultry chain in Ghana, Gambia and South Africa. Mr Van Horne is involved in several international networks. To mention two: he is economic analyst for the International Egg Commission (IEC) in London and chairman of working group 1 (economics) of the European Federation of the World Poultry Science Association (WPSA). Being a chairman of working group1 he organised in total seven round table symposia in different European countries. Since 1992 he has visited many World Poultry Conferences, mostly as an invited speaker (such as Beijing, Brisbane and Istanbul).

Bernd Kaspers graduated in Veterinary Medicine in 1986 from the University of Munich and received his Doctor of Veterinary Medicine degree in 1989. In 1991 and 1992 he worked as a postdoctoral fellow at the United States Department of Agriculture in Beltsville, MD where he did research on the immune response to coccidosis before returning to Munich. Since 1997 he is a Professor for Animal Physiology at the University of Munich, Faculty of Veterinary Medicine. He has more than 25 years of research experience in avian immunology which is documented by more than 100 peer-reviewed publications. He is co-editor of “Avian Immunology” published in a 2nd edition in 2014. He is actively involved in the Avian Immunology Research Group (AIRG) and has hosted the 2004 and 2016 AIRG symposia in Munich.His work involves research on both the innate and adaptive arms of the avian immune system with a particular focus on host-pathogen interaction, immune system maturation and mucosal immunity. Through this he has developed a broad range of tools for avian immunology research such as CD-markers, recombinant cytokines, bio-assays and technologies for functional in vivo studies which have been made available to the international avian research community. Prof Kaspers received funding from the European Union, the German Research Foundation (DFG) and the German Ministry for Education and Research. He also coordinated a DFG funded Graduate School at the Faculty of Veterinary Medicine in Munich.


Jack grew up in the Netherlands and received B.Sc. and M.Sc. degrees from the Wageningen Agricultural University and a Ph.D. from the University of Wisconsin in Animal Breeding. From 1989 to 1997 he was on faculty at the University of Guelph, working closely with the Canadian industry on genetic improvement of dairy cattle. He moved to Iowa State University in 1997, where he currently is a C.F. Curtiss Distinguished Professor and Leader of the Animal Breeding and Genetics group. Current research focuses on the genetic basis of feed efficiency and health in pigs and poultry, and on the integration of quantitative genetics and genomics in breeding programs.


Ilias Kyriazakis is the Professor of Animal Science at the Institute for Global Food Security of Queen’s University Belfast. He is a veterinarian by training who specialises in the effects of animal management on their performance, the ability to cope with challenges, such as pathogens, and their environmental impact. He has worked with a variety of animal species ranging from mice to cows, but more recently his research has focused on pigs and poultry. His recent work in poultry addresses: 1) the effect on nutrition on the ability of birds to cope with pathogens, such as coccidian; 2) the use of alternative and home grown feeds in poultry systems and 3) the development of methods to assess the environmental impact of local and global poultry systems. His team was responsible for the assessment of the environmental impacts of the UK poultry systems and the identification of hotspots responsible for such impacts. Professor Kyriazakis is the recipient of several awards, including the Leroy Award by European Federation of Animal Sciences (EAAP) for International Excellence in Animal Science, and Fellow of national and International bodies.

Jae Yong HAN

Prof. Han, Jae Yong received his bachelor and master degrees in Seoul National University, Korea. Since his completion of Ph.D. degree in University of Minnesota in 1991, he appointed as a professor of Department of Agricultural Biotechnology, Seoul National University. His academic specialties are avian transgenesis, genome editing and germ cell biology. He has made outstanding achievements in his researches on production of avian germline chimera by germ cell manipulation and genome editing. Specifically, his laboratory developed in vitro long-term culture system of chicken primordial germ cells (PGCs) for subsequent genome modulation of the PGCs. More recently, he has expanded to his research to early embryo development of avian species for in depth understanding of germ cells as well as embryo itself. Up to date, he has published more than 200 research articles in the internationally prominent journals. Based on the his achievements, he was awarded 2012 World’s Poultry Science Association Award (Research), and now he runs the project “Center for Avian Germ Cell Modulation and Cloning” awarded by National Research Foundation of Korea.

Dominic WRIGHT

I am an evolutionary biologist, with my research group focusing on the genetic basis of domestication, feralisation and the behaviour. We are part of AVIAN, the Behavioural Genomics and Physiology group at Linköping University. My group uses the twin processes of domestication and feralisation to unravel the genetic basis of complex traits. Domestication is an incredibly central process throughout civilization, with widespread effects on the target animal populations. Species like the modern domesticated chicken have experienced enormous selection over the past 8 000 years for everything from size, to color, to anxiety behavior. In contrast, when domestic animals escape or are released into the wild, they will re-adapt to the natural environment whilst being subject to natural and sexual selection once again in a process known as feralisation. Both feralisation and domestication provide powerful tools for studying the effects of such selection.

Thomas HEAMS

Thomas Heams was trained in life sciences and agronomy at AgroParisTech from 1997 to 2000, followed by a Ph.D (2004) in molecular and cellular biology at the French National Institute of Health and Medical Research (INSERM). He became an Assistant Professor in Animal Functional Genomics in 2006 in the Life Science and Health division of AgroParisTech and at the French National Research Institute for Agriculture, Food and Environment (INRAE). He currently is the coordinator of a M2 Master program in Predictive and Integrative AniMal biology (PRIAM) for Paris-Saclay University and the French coordinator of the European Master in Animal Breeding and Genetics (EMABG). His research focuses on animal genomics and on philosophy of sciences, and he develops a critical epistemology of life engineering, in connection with interdisciplnary animal studies and evolutionary theory
