Hofmann w flagRegina Hofmann-Lehmann is professor for Laboratory Medicine and Head of the Clinical Laboratory of the Vetsuisse Faculty, University of Zurich.


The multivalent laboratory receives 30’000 samples/year from patients of the teaching hospital and from zoos mainly for hematology, cytology, clinical chemical and serological and molecular analyses of infectious diseases. The Clinical Laboratory has been accredited by the European College of Veterinary Clinical Pathology (ECVCP).


Since 2011 she is Head of the Center for Clinical Studies, a core facility dedicated to support the laboratory-based clinical research of the Faculty of Veterinary Medicine (Vetsuisse Faculty) with more than 150 users from 27 research groups.


From 1998 to 2001, she was a researcher studying retrovirus infections at the Dana-Farber Cancer Institute and Harvard Medical School in Boston and in 2004 she received as the only veterinarian so far a professorship of the Swiss National Science Foundation (SNSF). Since 2010 she serves as President of the Swiss Association of Veterinary Laboratory Diagnosticians.


Her main research interests are in clinical infectiology with a focus on retroviruses, haemoplasmas and infections in domestic and wild felids. She is the author of >250 publications in peer-reviewed journals in this field. Her research has been funded by the SNSF since 1998 and involves collaborations with many research groups worldwide.


Since 2017 she is also Head of the Department of Clinical Diagnostics and Services at the Vetsuisse Faculty and Member of the Executive Board of the Animal Hospital of the University of Zurich.
