 Prof. Dr. Ger Rijkers (Head of Department)

Profile

Ger Rijkers (1952) is Professor in the Biomedical and Life Sciences and Head of the Science Department of University College Roosevelt in Middelburg, The Netherlands. At UCR, he is coordinator of the Life Sciences track as well as the Biomedical track and the Pre-Medical program. Rijkers coordinates the research program “Maintaining Health”, which includes research on early detection of dementia (Gerda Andringa and Nathalie van de Zande) as well as research initiatives on biobased economy. In 2014 and 2015 he was Director of Research a.i. He is also a part of the i-4-1-Health project: http://www.ucr.nl/i41health.

He also works as a senior scientist at the Laboratory of Medical Microbiology and Immunology of the St. Antonius Hospital in Nieuwegein. Dr. Rijkers graduated as cell biologist from the Wageningen University in 1977 and finished his PhD thesis on The immune System of Cyprinid Fish in 1980 at the same university. Next he started working in the Laboratory of Pediatric Immunology of the Wilhelmina Children’s Hospital in Utrecht (which now is part of the UMC). In 1984 he became a qualified medical immunologist. Dr. Rijkers has spent 2 sabbatical periods in the USA: in 1983 in the Lab of Don Mosier, at Fox Chase Cancer Center in Philadelphia and in 1989 in Denver in the Lab of John Cambier at National Jewish. From the Children’s Hospital he went to the Department of Surgery of the UMC Utrecht to work on mucosal immunology of the gastrointestinal tract.

Ger Rijkers has a wide  research interest with emphasis on mucosal immunology, immunoregulation (in autoimmune diseases, allergic diseases and infections), interaction between gut microbiota and the immune system, and vaccination. Rijkers has published over 300 papers in peer-reviewed scientific journals. He is Section Editor for the journal Beneficial Microbes and member of the Editorial Board of Pneumonia. In 2009 he published (as editor in chief) the textbook “Immunologie” (ISBN978 90 313 4263 1); the second edition will be published in 2016.

In the St. Antonius Hospital he (co)supervises eight PhD students who perform research on both clinical as well as fundamental aspects of the interaction between microbes and the immune system.

Ger Rijkers has a broad experience in teaching, ranging from guest-lectures at primary school children to postgraduate masterclasses on allergy, autoimmunity and vaccination. He has set up medical courses on Immunity and Infection as well as Metabolism and Endocrinology. In his spare time he is running and cycling and collects rock music from the sixties and seventies.

Ger Rijkers is married to Riky Lievendag since 1975 and they have 3 sons and 1 grandson.
