Honorary Fellows

Honorary Fellows are persons of eminence in the field of equitation science who have contributed significantly to the mission of ISES.

 Andrew McLean
Andrew holds a degree in Zoology, a PhD in horse training psychology and teaches at Universities and conferences around the world. He developed and manages the Australian Equine Behaviour Centre, the internationally recognised horse training and behaviour modification centre in Australia. 

Andrew has been an accredited horse-riding coach for over 20 years and has written top-selling books and numerous articles. He competed at state and national events in FEI level dressage and eventing and has also show-jumped to Grand Prix level.
Natalie Waran 
Natalie gained a BSc (Hons) in Zoology and her PhD in Cambridge. She led and participated in a wide range of research activities extending from welfare issues associated with agricultural animals to the assessment of conditions for companion, laboratory and zoo animals. Natalie has directed the Masters in Applied Animal Behaviour and Animal Welfare in Edinburgh. She is first or co-author of more than 100 scientific publications and editor of a book on the welfare of horses.

Natalie has owned, trained and competed horses for eventing at advanced level and has an interest in dressage.

Paul McGreevy
Paul is a riding instructor, veterinarian and ethologist. He is Professor of Animal Behaviour and Animal Welfare Science at the University of Sydney’s Faculty of Veterinary Science. The author of over 170 peer-reviewed scientific publications and six books, Paul has received numerous Australian and international awards for his research and teaching innovations. His PhD was in the behaviour of stabled horses but it was a chapter in his Equine Behavior textbook (co-written with Dr Andrew McLean) that coined the term “Equitation Science”. Paul’s term as Hon. President of the ISES delivered the Eight Principles of Ethical Training, the ISES Ethics Committee, the first Consensus Workshop on Research Methods, the Position Statement on Restrictive Nosebands and the ISES Taper Gauge. He is co-founder of the ISES Society. 

Hilary Clayton
Professor Hilary Clayton is a horsewoman, veterinarian and researcher. She grew up in England, graduated as a veterinarian from Glasgow University and has worked in veterinary colleges in the UK, The Netherlands, Canada and the US. She has done extensive research on locomotor mechanics, exercise physiology and conditioning programs for equine athletes. Dr. Clayton is the first incumbent of the Mary Anne McPhail Dressage Chair in Equine Sports Medicine at Michigan State University. She is a past president of the Association for Equine Sports Medicine and a member of the International Equine Veterinarians Hall of Fame.

Katherine Houpt
Professor Katherine Houpt received her veterinary and PhD degree from the University of Pennsylvania. She is professor of Animal Behavior at Cornell University College of Veterinary Medicine and has been studying horse behavior and welfare, investigating flehmen, environmental preferences, welfare issues of tethered mares, and cribbing. She directs the Animal Behavior Clinic and has written a text book 'Domestic Animal Behavior'. 

She is a horse crazy girl who never grew up and has ridden badly on 5 continents. She trail rides on an Arabian horse.

Jan Ladewig
Professor Jan Ladewig holds a PhD degree in Animal Behaviour from University of California, Davis, USA. He worked as a research associate in Germany, conducting research on behavioural and physiological reactions to stress in cattle, pigs and horses, as well as measurement of motivation in pigs by operant conditioning procedures. He is now a professor in domestic animal behaviour and welfare at the Copenhagen University, Denmark. 

Jan has been an active rider since childhood. He is particularly interested in the scientific background of training horses, as it relates to riding safety and horse welfare.

Frank Ödberg
Professor Frank Ödberg holds a PhD in Experimental Psychology (Ghent University) and an MSc in Zoology (Edinburgh University). He has contributed to the development of applied ethology since 1968. His research interests focussed on the study of ethological and neurobiochemical determinants of conflict-induced stereotypies and on horse behaviour. 

He has been riding since childhood, competed in dressage and trained horses up to the high school. He is an advocate of the more animal-friendly baroque riding philosophy.
