Lecturer ANIVADO & 
Expert in Equine Sport Physiology

Lecturer ANIVADO & 
Expert in Equine Behaviour and Welfare

Dr Andrea Ellis is a renowned equine scientist, who has had horses in her blood from an early age both as an artist and scientist. She freely admits that she occasionally missed her first two school lessons and secretly went to see the training sessions at the Spanish Horse Riding School near her home in Vienna. 

Andrea's early research focused on food intake behaviour and nutrient digestion in horses and sheep and set her on a path of becoming a specialist in equine nutrition and behaviour. After working as a Scientific Researcher at the Research Institute for Applied Husbandry, Wageningen University Research, The Netherlands, for four years, she joined Nottingham Trent University as a Senior Lecturer, where she led the design of the MSc in Equine Health and Welfare and was Programme Leader of this course.


Dr Carolien Munsters holds an MSc in biology and worked as a senior project manager at the Equine Fieldlab at the Dutch Equestrian Centre. In 2010 she started Moxie Sport Analysis and Coaching, where she combines "research knowledge with (top)sport analysis to guide and support equine athletes, trainers and coaches”. In 2013 she completed her PhD on workload, fitness and welfare of riding horses at the Faculty of Veterinary Medicine of Utrecht University. 

She has been the official advisor for the Olympic eventing team regarding exercise testing and training programs for more than 8 years and guided the riders and horses towards the Olympic games in London and Rio. In addition, she advises and guides several international and national riders (eventing, dressage, showjumping, carriage driving, endurance) on how to optimise their training program for their horses. In preparation for numerous European and World championships, she analyses the fitness of sport horses (and teams) and helps them to construct an optimal training program towards their championships. Continued monitoring of all training sessions and competitions of these horses is her main focus as in this way training programs can be maintained most optimal for horse and rider. 

In addition, she gives numerous courses about equine exercise physiology as a certified lecturer of riders, trainers, physiotherapists and veterinarians and conducts several research projects in collaboration with the Faculty of Veterinary Medicine of Utrecht University.

Dr. Machteld van Dierendonck has been working as a behaviour specialist, scientist and practitioner in the field of (equine) behaviour and welfare (assessments) for the last 15 -20 years. She started working for the Equine Clinic of the Veterinary Faculty of Utrecht The Netherlands in 2001, since 2016 she founded and works as the clinical ethology specialist at the Equine Behavioural Referral Clinic at the same faculty.

Besides these functions, she has established her own Equine Clinical Ethological referral practice Equus Research & Therapy. Since 2012 she is a part-time visiting professor at the Faculty of Veterinary Medicine both in Ghent and Antwerp, for courses in (equine) Ethology and Animal Welfare.

In 2010 she became board-certified as an associate of the ECAWBM as (Equine) Veterinary Behaviour Specialist; in 2013 she became also an associate for the subspecialty Animal Welfare Science-Ethics-Law. Her current work mainly consists of research, teaching (graduates and postgraduates), and treating equine patients with (additional) behaviour problems. In scientific research, the current focus is on measuring welfare in horses (at individual and farm levels) and pain and pain assessment in horses and donkeys (EPWA app). She now has> 30 peer-reviewed publications to her name and several scientific book chapters. She is a founding member of ISES (International Society of Equitation Science).

Carina Steendam

Lecturer ANIVADO & 
Equine Nutritionist

Carina Steendam holds a Master’s Degree in Animal Nutrition from Wageningen University (WUR). She has been involved in research projects related to the nutrition of monogastric animals (e.g. J Nutr 2004, 134(11), 3076-3082). She has a special interest in the effects of antinutritional plant components on gastrointestinal tract health.

Carina is a lifelong horse lover, an amateur rider, and a riding instructor. Together with her partner, she is a keen breeder of KWPN horses. She has been a lecturer at the van Hall University of Applied Science with an emphasis on equine nutrition, but also on teaching equine behaviour and exercise physiology.  She writes for equestrian magazines and a professional magazine of the feed industry to educate a wide audience about equine nutrition and health. She is the author of various articles related to horse nutrition in the Netherlands and she aims to bridge the gap between science and practical feeding management. Her enthusiasm for nutritional sciences equals her love for horses, and according to her, equine nutrition is combining the best of both worlds.
