Dr. Katrin Hinrichs is Professor and Patsy Link Chair in Mare Reproductive Studies in the College of Veterinary Medicine & Biomedical Sciences, Texas A&M University. She obtained her DVM from the School of Veterinary Medicine at UC Davis and her PhD from the University of Pennsylvania. Dr. Hinrichs has pioneered research into equine assisted reproduction, producing the first cloned horse in North America and developing the first successful program for equine intracytoplasmic sperm injection (ICSI) and in vitro embryo production in the US. Her research has led to new methods for shipment of immature oocytes, biopsy of equine embryos, and for cryopreservation of expanded equine blastocysts, all now utilized worldwide. Dr. Hinrichs has received honors including Theriogenologist of the Year from the American College of Theriogenologists, an honorary doctorate from the University of Copenhagen, and the  2016 Simmet Prize for Assisted Reproduction from the International Congress of Animal Reproduction.  




Tullis Matson has worked in the equine industry for over 25 years.  He began running the small natural covering stud at the family farm in 1989.  In 1990 went to New Zealand to learn the practice of Artificial Insemination before returning home to set up one of the first equine AI only units in the UK.  


Stallion AI Services Ltd was formed in 2000 and is one of the most successful stallion collection centres in Europe, offering semen collection services, fertility assessment and worldwide semen export.  We have collected from over 1100 stallions, across 51 different breeds.


In recent years, Tullis has carried out research into semen collection, stallion fertility and cryopreservation methods of equine semen and embryos.  He has developed bespoke extenders for stallions and harvested semen from post castration testicles. He lectures worldwide on equine breeding and stallion management and also works with organisations such as Chester Zoo to help cryopreserve semen from endangered species e.g. Rhino, Lion.

Niamh graduated from the Royal Dick School of Veterinary Medicine, University of Edinburgh in 2008 and started her career in Ireland. Niamh then spent several seasons between Australia, UK, USA and Saudi Arabia. Niamh completed a residency in Equine Reproduction at the University of Liverpool, during which time she set up the first commercial equine intracytoplasmic sperm injection (ICSI) centre in the UK in collaboration with Twemlows stud farm. The first ICSI foal was born in 2015.

Niamh is a diplomate of both the American College of Theriogenologists and the European College of Animal Reproduction. Most recently Niamh completed a PhD entitled "A metabolic approach towards optimising equine in vitro maturation" which was a collaborative BBSRC funded project between the University of Liverpool, University of Manchester and Texas A&M University.

Steve has worked in the field of human clinical embryology for over 30 years starting in Manchester, where he completed a PhD in male infertility and the acrosome reaction. Before his recent role as the Scientific Director of IVI UK, Steve was the Scientific Director of Liverpool Women's Hospital’s Hewitt Fertility Centres, one of the UK’s largest providers of assisted conception. In addition to dealing with the many day-to-day ‘hands-on’, managerial and research responsibilities of a Consultant Clinical Embryologist, he is fortunate to have been afforded a broader perspective as a Scientific Inspector and advisor for the UK Regulator, the Human Fertilisation and Embryology Authority. Steve has been very much involved in clinical embryology as a profession and is proud to be the current President of the UK’s Association of Clinical Embryologists (ACE). Steve is Visiting Reader in Reproductive Medicine at Edge Hill University, and as an Honorary Senior Fellow at the University of Liverpool, he supervised the development of the equine ICSI lab at the University’s Leahurst Campus. Steve now works independently as a Consultant Reproductive Scientist based in the UK.

Patrick Brogan graduated from the University of Sydney in 2005 and worked for 4 years in specialised Equine practice in Scone, Australia. In 2009, he made the move to Murdoch University in Perth, Western Australia to undertake a Research Masters in Equine reproduction and started an Equine Reproduction Referral service there. In 2010 he passed examinations in Animal Reproduction to become a member of the Australian college. In March 2012 Patrick arrived in the Netherlands to commence a residency at the University Of Utrecht and in 2015 passed examinations to become a Diplomate of the American College of Theriogenologists. Applied clinical research in semen storage and embryo transfer has formed the basis of his work to date. He has recently become a member of the KWPN and bred his first foals in 2015. He plans to stay in Netherlands for now and is starting his own business and specialist reproduction service Equiception – Equine Conception Solutions in 2016.




Simon graduated from UCD in 2007 and spent his first few years as a stud vet in Ireland, Australia and New Zealand. Simon then turned his attention to surgery and completed a surgical residency at the University of Liverpool becoming a Diplomate of the European College of Veterinary Surgery in 2016. Simon is now the resident surgeon at Lisadell Equine Hospital. Simon has maintained his interest in equine reproduction from a surgical standpoint these days. He performs a wide range of reproductive surgical techniques on mares and stallions, but is especially interested in laparoscopic techniques and their use in treating mare fertility.




Dr. Barbara Anne Murphy is Head of Equine Science and Programme Coordinator of the BAgrSc Animal Science – Equine degree within the School of Agriculture and Food Science at University College Dublin. Having worked for leading equine breeding operations in the US and Ireland, she combines expertise gained from both her academic equine science background and equine industry experiences to oversee a relevant and highly competitive degree programme. Following a BSc in Equine Science from the University of Limerick, she spent a year working within the Thoroughbred industry before pursuing a PhD in Veterinary Science at the Gluck Equine Research Center, University of Kentucky. Her widely read PhD Dissertation entitled “Investigations of circadian regulation and immune-circadian interaction in the horse” shone light for the first time on a new area of equine science research – chronobiology. Her current scientific research relates to studying how environmental cues, primarily photoperiod, regulate biological rhythms in animals. Specifically, her studies investigate how circadian and circannual rhythms are involved in important reproductive phenomena and how disruption of these rhythms impacts growth, health and performance in the equine and bovine species.


Barbara is also Founder and CSO of Equilume Ltd, a spin-out company from University College Dublin that has developed the Equilume Light Mask for the provision of mobile light therapy to horses, and the Equilume Stable Light which provides circadian and circannual lighting to horses for improved health and performance.
