Dr. Renes started his scientific career in cancer research at the University of Groningen, The Netherlands on drug resistance mechanisms mediated by the ABC transport protein MRP1. With his interest in protein function he worked in the industry to set up a proteomics research line in relation to resistance mechanisms of lactic acid bacteria for the gut-intestine environment. In 2001 Dr. Renes was appointed as Assistant Professor at the Maastricht University, The Netherlands where he combined his interests in metabolic research and proteomics in the field of obesity research with a focus on adipocyte biology and adipokine function. He set up a proteomics laboratory at the Department of Human Biology and expanded its activities on in vitro and ex vivo research. In 2006 Dr. Renes was awarded a Netherlands Genomic Initiative Fellowship to visit the laboratory of Prof. Ole N. Jensen (Protein Research Group, SDU, Odense, Denmark) to learn and apply advanced mass spectrometry technologies. During this visit he focused on application of LC-MS/MS in analysis of membrane proteins from (pre)adipocytes. The current research interest is directed to human adipocytes and their function in inter-organ signalling, with special emphasis on cancer. Since 2018 Dr. Renes is appointed as lecturer. His work is currently focussed on education. In this position he is coordinator of the specialisation Biology and Health (bachelor Health Sciences) and coordinator of the courses Cell Signaling (BBS2042) and Critical Appraisal of Biomedical Publications (BBS1006) from the bachelor Biomedical Sciences. In 2018 Dr. Renes was awared the FHML eduction prize for best tutor, while the course Cell Signaling was nominated for best course.
