Dr Julien Dandrieux (BSc, Dr med vet, DACVIM, GCUT, PhD, MRCVS)

Senior Lecturer in Small Animal Internal Medicine


I have completed my Veterinary Medicine degree in 2002, followed by a rotating internship and thesis at the University of Bern. I did my specialist training in Small Animal Internal medicine as a joint program between the University of Bern and Louisiana State University and became a Diplomat of the American College of Veterinary Internal Medicine in 2008. 

I have then worked in the UK as a lecturer in Small Animal Medicine at the University of Liverpool and then as a medicine consultant at IDEXX before moving to Australia. I have completed my PhD at the University of Melbourne in gastroenterology and worked as a Senior Lecturer in Small Animal Medicine until May 2022. I have also been locuming in both private and academic referral clinics in Australia and in the UK during this period. My research focuses includes gastro-intestinal diseases, immune-mediated disease, and use and monitoring of pets treated with immunosuppressant drugs.

I am a passionate clinician and teacher and especially interested in clinical research to improve evidence-based medicine. Outside work, I enjoy spending time with my family and exploring the outdoors.

Research summary

I am passionate of clinical research, in particular in small animal gastroenterology. My research has been focusing on the role of macrophages in canine chronic enteropathy (CE), long-term response to treatment, and more recently faecal microbiota transplants (FMT) as an alternative treatment to manipulate the microbiome. I have also a strong interest in the use and monitoring of immunosuppressant drugs for animals with immune-mediated disease (including pharmacokinetics and pharmacodynamics). Most of my research is multi-disciplinary with worldwide collaborators.

Current research interests

My current research in gastroenterology includes to develop the use and understanding of FMT in dogs and cats. I am also part of the FMT Consortium, which include veterinary gastroenterologists worldwide, to develop guidelines and improve FMT understanding and research. I am also interested in the role of macrophages in dogs with CE and aim to better define the subtypes of macrophages present in dog’s intestines. An additional interest in gastroenterology is to improve our understanding of dogs with protein-losing enteropathy with a focus on treatment options.
