The Wildlife Medicine group aims to develop, improve, and provide state of the art, research-oriented and species-specific zoo and wild animal medicine.

Our work covers broadly clinical and research aspects of zoological medicine. The interdisciplinary nature of our group offers advanced and high-standard services and expertise in the fields of internal medicine, anaesthesia and analgesia, diagnostic imaging, reproduction, and comparative pathophysiology. Moreover, through its engagement in scientific research provides novel techniques and approaches on capture and health management of both individual wild animal and wildlife populations/groups (captive or free ranging).

Wildlife conservation and animal welfare considerations are integrative principles of all our research and veterinary work.

Our Team

Our team covers a wide variety of veterinary disciplines, which are adapted to accommodate the diversity of the respective species treated.


Gabrielle Stalder doing field work

Dr. Gabrielle Stalder

Dr. Gabrielle Stalder is head of the working group. She is involved in a wide range of research on wildlife anaesthesia, wildlife diseases and ecophysiology of wildlife species. Her research interests include the microbiome and the ecophysiological acclimatization of wild animals.


Dr. Johanna Painer with anaesthetised bear

Dr. Johanna Painer

Dr. Johanna Painer is an expert in advanced ultra-sonography, reproductive management, internal medicine and animal welfare. As such, she works in various research and conservation projects concerning wildlife anaesthesia, reproductive management, biomimetics and wildlife crime.


Dr. Friederike Pohlin with rhino

Dr. Friederike Pohlin

Dr. Friederike Pohlin has a broad scientific background in wildlife anaesthesia and game management.  Her current research is directed towards improving wild animal immobilisation and the assessment of stress and animal welfare during wildlife translocation.


Dr. Szilvia Kalogeropoulu

Dr. Szilvia K. Kalogeropoulu has an extensive scientific knowledge in zoological medicine. Her current research is focusing on the systemic effects of chronic-low grade inflammation in different captive as well as traded and farmed wildlife species (biomimetic approach). 
Szilvia Kalogeropoulu is also currently replacing Johanna Painer-Gigler during maternity leave.

Hathaipat Rattanathanya, DVM

Hathaipat Rattanathanya is a veterinarian and is currently doing her PhD. Her thesis focuses on developing new ways to treat opioid-induced adverse effects in etorphin-immobilized ungulates.


Anita Metzinger

Anita Metzinger supports our team as a student assistant. Anita studied biology and is currently in the last year of her study of veterinary medicine at the University of Vienna and her Master's degree in wildlife management and ecology.  She actively contributes to research and is committed to hands-on learning in wildlife medicine. She is currently writing her diploma thesis on the histomorphology of the rhinoceros spleen and her master's thesis on chronic kidney disease in big non-domestic felids.
