After meeting Professor John Summers there, he went on to do his masters at the University of Guelph in Canada on poultry amino acid nutrition (1981-1984). He then completed his PhD at the University of Guelph (1984-1988) on interaction of nutrition with poultry polyamine biochemistry, with post-docs at McGill (Montreal, 1988-1989, D Zadworny) and Saskatchewan (1989-1991, Hank Classen) in molecular biology and enzymes in poultry nutrition respectively. He has worked in the industry on feed enzymes principally at Finnfeeds International (1991-2001), Zymetrics (2001- 2007) and finally AB Vista (2007-present) where he has been the director of research for almost 20 years. Mike has produced over 350 publications, including more than 250 full refereed journal articles, principally in the field of feed enzymes, more than 30 popular press articles and six book chapters. He has also published three books, including three editions of Enzymes in Farm Animal Nutrition.Michael KogutDr Kogut is a research microbiologist and lead scientist at the Southern Plains Agricultural Research Centre, College Station, Texas. He has published over 220 peer-reviewed scientific papers, 20 book chapters and has received five patents. Dr Kogut%u2019s research has concentrated on the development of cost-effective immunological interventions to improve gut health of poultry by studying the role of the microbiota in immunity to infection, the role of dietary metabolites in promoting immune regulation and immune responses to enteric bacterial pathogens, characterising novel molecular targets that mediate the actions of dietary compounds in gut inflammation and immunity, and understanding the integration of central metabolic pathways and nutrient sensing with antimicrobial immunity. Dr Kogut is a Poultry Science Association Fellow and is the current editor-in-chief of Poultry Science.Sonia LiuAssociate Professor Sonia Liu is a poultry nutritionist from the University of Sydney. Her research focuses on reduced protein diets, digestive dynamics of nutrients, amino acid nutrition in layers and broilers and feed grain quality. Sonia has more than 100 peer-reviewed scientific publications. She was the recipient of the 2015 Department of Agriculture, Fisheries and Forestry%u2019s Science and Innovation Award for Young People, the 2018 Australia Awards %u2013 Endeavour Research Fellowship and the 2019 Australia Research Council%u2019s Discovery Early Career Researcher Award. Recently, Dr Liu won the ARC Early Career Industry Fellowship. This was on top of the ARC Linkage Project she secured earlier this year, worth over $1 million, to examine the use of reduced protein diets in poultry production.Walter BottjeProfessor Walter Bottje received his PhD at the University of Illinois and was hired in 1985 in the Department of Animal Science at the University of Arkansas. He served as head and director for the Centre of Excellence for Poultry Science (2002-2008). Starting in 2001, his research focused primarily on understanding the cellular basis of feed efficiency. He currently serves as project director of a USDA NIFA Sustainable Agriculture System grant (#2019-69012-29905), %u2018Empowering the US broiler industry for transformation and sustainability%u2019. This is a multi-institutional comprehensive grant that includes research, teaching and extension activities with a major focus on water use efficiency to help meet challenges facing the poultry industry in an increasingly hot, crowded and hungry world.Martha Pulido-LandinezHolding a DVM and Master of Science in animal health and production from the National University of Colombia, College of Veterinary Medicine and Animal Husbandry. Doctor of Veterinary Sciences from the Federal University of Rio Grande do Sul, Porto Alegre, Brazil, College of Veterinary Medicine, American College of Poultry Veterinarians %u2013 ACPV, diplomate. With special training from the University of Georgia College of Veterinary Medicine, Poultry Diagnostic and Research Centre, training in avian virology and histopathology, visiting scientist at the US Department of Agriculture, Agricultural Research Service, Egg Safety and Quality Research Unit, and short term scholar at Mississippi State University, Poultry Research and Diagnostic Laboratory. Martha has 33 years experience in poultry medicine with an emphasis on salmonella control, emerging bacterial diseases (enterococcus sp) and antimicrobial resistance.Frank WongFrank is a senior research scientist with the CSIRO Australian Centre for Disease Preparedness International Program, where he serves as the World Organisation for Animal Health reference laboratory expert for avian influenza. He currently chairs the executive committee of the WOAH-FAO network of expertise on animal influenza and the OFFLU avian influenza technical working group. He represents OFFLU on WOAH/FAO/WHO tripartite activities on pandemic influenza preparedness and surveillance. At ACDP, Frank serves as the science lead for regional animal health laboratory capacity building and EID surveillance projects at the wildlife interface with southeast Asian countries. He also contributes to ACDP%u2019s national emergency animal disease response activities that advise state and federal government agencies on animal influenza outbreaks in Australia. His research interests include molecular epidemiologic surveillance of emergency transboundary animal diseases, viral pathogen phylodynamics and the development of sustainable viromics-based surveillance approaches that could contribute to emergency infectious disease preparedness in the Asia-Pacific region.Steve LeesonAn expert in poultry nutrition and production, Steve Leeson PhD is a consultant Professor Emeritus at the Ontario University of Guelph in Ontario, Canada. As a researcher, his primary areas of study included the potential for manipulation of eggs and poultry meat as it impacts human health. He previously worked on incorporating omega-3 and other polyunsaturates into eggs and studied the transfer efficiency of lutein into eggs. Lutein is known to sustain eye health in humans and Dr Leeson affirms eggs will likely become a major dietary source of this nutraceutical. His other research projects involve the use of medium-chain triglycerides to impact gut health in the absence of antibiotic growth promoters. He has published over 340 papers in referred journals and made over 1000 presentations at scientific and industry meetings. He%u2019s published eight books on poultry nutrition and management, including as co-author of the book Commercial Poultry Nutrition.Pairat SrichanaDr Pairat Srichana started his career in feed technical service at feed technology of Charoen Pokphand Group. In 2002, he was offered a university scholarship in the field of animal nutrition. He received his doctoral degree in 2006. After receiving a PhD in animal science nutrition from the University of Missouri-Columbia in the US, he was appointed chair of the Feed Research and Innovation Centre at CPF (Thailand) PCL. Dr Pairat has over 30 years of experience in feed research and animal nutrition. As the head of animal feed research and development, he was in charge of experimental data, statistical analysis, feed formulation, feed management, feedstuff quality and dietary supplement evaluation, enabling Dr Pairat to accumulate an in depth understanding of animal feed. In this role, Dr Pairat was also invited as a special instructor. He currently teaches introductory animal nutrition courses at undergraduate level and is a co-instructor for a graduate level course.Sanna SteenfeldtWith a MSc (Biology) (cand.scient.) from the Aarhus University in 1988 and a PhD (poultry science) from the Royal Veterinary and Agricultural University in Denmark in 1995, Dr Sanna Steenfeldt is employed at the Aarhus University%u2019s Department for Animal and Veterinary Sciences as senior researcher. Dr Steenfeldt is the project manager of and participant in many research projects dealing with different topics related to poultry nutrition, physiology and production in both conventional and organic production. These include feedings strategies for broilers and allometric measures, nutritive value of feed ingredients for broilers and effect of fibres on intestinal viscosity, passage rate and nutrient digestibility, phosphorus and calcium levels in broiler and layers diets, and strategic allocation of calcium and the effect on performance, retention and leg health. Dr Steenfeldt teaches at several BSc and MSc courses and is experienced as supervisor for BSc, MSc and PhD students.Vitor ArantesVitor Arantes is an experienced poultry nutritionist and technical services expert with over 15 years in the field.
