Philippa Bucknell BSc (hons) BVM&S MRCVS AFHEA

DVetMed postgraduate University of Nottingham and Twycross Zoo

Pip qualified as a Vet in 2016 and commenced the DVetMed (Zoo Animal Medicine and Surgery) in association with the University of Nottingham and Twycross Zoo in July 2021.

Pip’s research will be continuing the valuable work of Sophie Moittié and Victoria Strong, investigating the aetiopathogenesis of heart disease (particularly myocardial fibrosis) in Great Apes.

This will include interpretation of serum biomarkers, ECGs, echos, blood pressure and histopathology in order to better understand how best to diagnose, monitor and manage this significant cause of mortality in captive Bonobos, Chimpanzees, Gorillas and Orangutans.

Rachel Jarvis BSc (Hons), MSc
PhD Student at University of Nottingham

Rachel’s PhD project focuses on investigating the relationship between cardiovascular health, serum biomarkers and vitamin D levels in the European zoo chimpanzee population. As part of this, Rachel will spend time at Twycross Zoo learning from the team of clinicians via annual health checks, regular behaviour observations and clinical monitoring of the zoo’s great apes. Rachel aims to establish seasonal vitamin D reference intervals in chimpanzees, as well as validate species-specific, sensitive cardiac biomarker signatures through mass spectrometry-based proteomics and ELISA work at the University of Birmingham.

Kerstin Baiker,, Dipl ECVP, MRCVS, SFHEA
Clinical Professor of Veterinary Pathology at City University, Hong Kong

Kerstin is a certified Diplomate of the European College of Veterinary Pathology and currently works as a Clinical Professor at the Vet School in Hong Kong. She has been part of the Ape Heart project from the beginning and is keen on learning more about the aetiopathogenesis of cardiac diseases in great apes.

Mike Martin

Mike is a veterinary surgeon and has been a RCVS registered Specialist in Veterinary Cardiology since 1995 and revalided every 5 years ever since. His background has been in dog and cat speciality cardiology practice for over 25 years. However, he retired from clinical practice and the end of 2017. Now his focus is in training and education of veterinary surgeons. He has been involved as an adviser and consultant to the Ape Heart Project since 2014, bringing his specialist cardiology knowledge to help in research of heart disease in the great apes.

Professor Kate White
Professor of Veterinary Anaesthesia & Analgesia, University of Nottingham

Kate is Professor of Veterinary Anaesthesia and Analgesia and the Clinical Director of the Nottingham Vet School. Her research interests are in many aspects of pain assessment, analgesia and anaesthesia in companion, farmed, captive wild, and laboratory animals. Kate is particularly interested in descending controls and the role they play in acute and chronic pain in models of musculoskeletal disease. Kate teaches physiology, pharmacology, anaesthesia and analgesia across the 5-year curriculum and works in the clinical associate practices, and supervises undergraduate and postgraduate students. She is Senior Vice President of the Association of Veterinary Anaesthetists and also the anaesthesia consultant on the Ape Health project at Twycross zoo investigating health and disease in great apes.

Dr. Melissa Grant SFHEA
Senior Lecturer in Biological Sciences, School of Dentistry at University of Birmingham


Melissa Grant is a biochemist by training and a senior lecturer in biological sciences at the University of Birmingham’s School of Dentistry. Her research is focussed on understanding the role of inflammation in oral disease, with particular emphasis on the functions of white blood cells called neutrophils and detection of disease for instance in saliva. With the Ape Heart Project Melissa is interested in what role oral disease might play in heart disease and if heart disease might be detected in saliva. She is collaborating with others in the AHP on finding biomarkers and developing those into saliva diagnostic tests.

Dr Matyas Liptovszky
EBVS® European Veterinary Specialist in Zoo Health Management
Member of European College of Zoological Medicine


Dr Liptovszky is currently Director Life Sciences at Perth Zoo. Prior to this position he worked in a number of European and UK zoos both as a zoo and wildlife veterinarian and in different leadership roles. He worked in a wide range of field conservation and research projects in Europe, the UK, Asia, Africa, Central America and Australasia.

He graduated as a veterinary surgeon in 2005, while also earned a diploma in wildlife management during his studies. He holds a master in exotic animal medicine and an MSc in science communication. He is a honorary assistant professor of zoo animal medicine at the University of Nottingham, School of Veterinary Medicine and Science (UK) and veterinary advisor of the Western lowland gorilla EEP.

His main focus of interest is anaesthesia of nondomestic species, clinical research and conservation medicine.

Mat is currently collaborating with the project on various research projects.

Previous Staff

Sophie Moittié, LV, MRCVS, DVetMed postgraduate student 2016-March 2021

University of Nottingham and Twycross Zoo

Sophie Moittié qualified as a veterinary surgeon in 2009 and completed a 4-year postgraduate program with the University of Nottingham and Twycross Zoo in March 2021. This program combined general clinical work at the zoo as part of the vet team and Ape Heart Project studies in great ape cardiac diseases. 

Her research looked into the causes and mechanisms of heart disease in gorillas, chimpanzees, bonobos and orangutans. Her thesis investigated the accuracy of non-invasive blood-pressure devices in chimpanzees and the value of implantable loop recorders to detect arrhythmias in chimpanzees. She also completed research on the use of the dried blood spot method to measure vitamin D status in chimpanzees and the vitamin D status of the European chimpanzee population alongside continuing the histopathological examination of Great ape hearts.”

Dr Vicky Strong


Vicky qualified as a Veterinary Surgeon from the University of Liverpool in 2010 after having been awarded a First-Class BSc (Hons) in Veterinary Pathology from the Royal Veterinary College, London in 2008.

After 3 years in full time general (mixed farm and small animal) veterinary practice she embarked upon a 4-year doctoral training programme at The University of Nottingham and Twycross Zoo, and in 2017 was the first student to complete the University of Nottingham with the Degree of Veterinary Medicine (DVetMed).

The DVetMed involved a combination of doctoral research alongside clinical training in zoological medicine. Her doctoral thesis was entitled ‘Getting to the heart of the matter: an investigation into great ape mortality and cardiovascular disease’ and aimed to confront significant gaps in knowledge about these two key areas of interest.

Vicky carried out a mortality study to identify the main causes of death of great apes in zoos across Europe and wrote many of the Ape Heart Project protocols. She initiated and conducted a study carrying out detailed post-mortem examinations of great ape hearts and completed a piece of research looking at the effect of general anaesthesia on the heart.

Vicky continues to conduct research into great ape health and welfare in her role as Clinical Assistant Professor in Exotic Animal Medicine at the University of Nottingham’s School of Veterinary Medicine and Science.
