Head of the Laboratory of Livestock Physiology


My research in the last five years has been focussed on improving quality and welfare traits related to reproduction in chickens. I work closely with the breeding industry and use genetics, genomics and physiology and cross disciplinary approaches to understand these traits and develop new selection tools. I have three key priorities; 1) The control of feed intake in broiler parents, 2) Osteoporosis in layers, 3) Egg Quality, and a spin off 4) Novel Antimicrobial peptides from eggs. Additionally, I am generally interested in the control of avian reproduction. The most important results have been in the understanding of the central and peripheral control of food intake and metabolism in birds, the genetic architecture of osteoporosis and getting near implementation of cuticle deposition as a trait in breeding.


I'm research director and co-leader of the team "Egg defenses, enhancement, evolution". My research focuses on table eggs. We are studying its characteristics to meet the needs of consumers and producers and also to enhance the constituents of the egg for food and non-food purposes. I work more particularly on biochemistry and molecular biology related to the formation of eggs and their qualities. I have studied the formation of shells and the identification of proteins from its organic matrix, involved in the calcification process. I participated and coordinated several national and international research programs. My research is also focused on the high throughput methodologies used to identify and characterize the biological activities linked to the egg's natural defenses. I have published more than 70 publications in international scientific journals, 12 book chapters, and have been invited to present my results at more than 30 congresses and I count about 120 papers at conferences.

Dr. Tom Porter received his Ph.D. in Animal Physiology from the University of Minnesota in 1988. He conducted research as a Postdoctoral Fellow in the Department of Anatomy & Cell Biology at the Medical University of South Carolina. In 1993, he joined the Department of Poultry Science at Texas A&M University as an Assistant Professor, and in 1997, he was recruited to the Department of Animal and Avian Sciences at the University of Maryland, where he was subsequently promoted to Associate Professor and Professor. Dr. Porter has served the Poultry Science Association for more than 20 years as Associate Editor, Section Editor, and Editor-in-Chief of the journal Poultry Science. Dr. Porter’s research interests center on molecular and cellular endocrinology in poultry. Early in his career, he demonstrated that the production of steroid hormones in the ovaries of birds requires three different cell types, a situation which is different from that in mammals. One major focus of his research over the past 26 years has been on the mechanisms controlling cellular differentiation within the anterior pituitary gland during chick embryonic development. The overall goal of this research is to improve growth characteristics in broiler chickens through an increased understanding of the regulation of the bird’s own growth hormone production. Dr. Porter’s group has developed a working model for the regulation of growth hormone cell differentiation that involves hormones from other endocrine glands as well as nuclear transcription factors and signal transduction cascades. A second major focus in Dr. Porter’s laboratory has included genome-wide analysis of gene expression in the neuroendocrine system. The long-term goal of this research is to increase our understanding of global patterns of gene expression in the hypothalamus and pituitary gland and to identify the genes and gene networks controlling growth rate, body composition and feed intake in broiler chickens. Dr. Porter is the author of 101 refereed scientific papers, 22 book chapters or reviews, and 155 abstracts. His publications have been cited more than 2,000 times. Dr. Porter was named Fellow of the Poultry Science Association in 2016.


Bas Rodenburg is Professor in Animal Welfare at the Faculty of Veterinary Medicine of Utrecht University in The Netherlands. He is also Special Professor at the Adaptation Physiology Group of Wageningen University. He coordinates research and education in animal welfare. The research of Bas Rodenburg aims at improving the methodology for assessment of animal welfare, supported by sensor technology. He mainly wants to focus on behavioural indicators and methods where the animals themselves are ‘asked’ how they experience their living conditions. Bas Rodenburg obtained his PhD on feather pecking in laying hens in Wageningen in 2003 and since then he has been involved in feather pecking research. He has combined more basic approaches focusing on understanding the underlying mechanisms with more applied approaches focusing on successfully keeping flocks with intact beaks in non-cage systems. He is currently involved in the EU projects FreeBirds, ChickenStress and PPILOW, all focused on improving laying hen welfare and he recently acted as Vice Chair of the COST Action GroupHouseNet.


Mike McGrew is a group leader at The Roslin Institute, UK. He obtained his PhD from Boston University and pursued a research program in embryology at the IBDM in France. There, he was part of a research group that discovered a basic mechanism controlling the timing of the formation of body segments in vertebrates, now known as the ‘segmentation clock’. Afterwards, he joined The Roslin Institute in 2001 to help develop transgenesis in chickens for use in developmental biology and bio-pharming. His laboratory works on a type of stem cell in birds, the primordial germ cell, which makes the sperm and eggs of birds. These cells can be used to generate gene edited chickens, chicken which contain precise genetic changes in their genome. A benefit of this research will be the technology to create bio-banks (frozen aviaries) using germ cells. This is needed as the traditional methods used for species cryopreservation using semen and eggs are either inefficient or impossible in birds. Avian bio-banks will aid in the efforts to both manage and conserve both rare and industrial breeds of poultry. The future challenge is to extend biobanking to endangered bird species.


Marta Gariglio is a university researcher in the Department of Veterinary Sciences in the university of Turin, Italy. She is a member of the Italian branch of the World's Poultry Science Association. In 2019, she won the “Giulia Giordano per il miglior poster nell’area delle Zoocolture” award during the 23° Congress of the European Society of Veterinary and Comparative Nutrition. She participated in the writing of 13 published articles as well as 18 abstracts.

She is currently participating in different projects focusing on the sustainability of chicken and insect production.


Teun van de Braak (the Netherlands, born ’87) grew up in the Dutch country side, and there is where his poultry passion started. Since he was a young kid he bred poultry; varying from all different sizes and varieties (from Sebright chickens, to Rhea Americana’s). Inspired by James Herriot, he wanted to become a vet in later professional life. But things went into a different direction and Teun got enrolled in a bachelor program of Animal Sciences at Wageningen University in 2005, which was followed by a master in Animal Breeding and Genetics and a minor in business economics at the aforementioned institute. After receiving his MSc degree in 2010, he started off as a geneticist at the Laying hen Breeding department of Hendrix-Genetics. After working for 8 years in R&D, Teun made the move to product management. In this role he makes the connection between R&D and the commercial field.
