Kemmeren Group

Patrick Kemmeren

Patrick Kemmeren obtained his PhD in 2005 from Utrecht University for his work on analyzing and integrating genome-scale data. A postdoctoral fellowship obtained through EMBO and the Netherlands Genomics Initiative (NGI) allowed him to work at the University of California, San Francisco. Under the supervision of Nevan Krogan, he worked on the definition of an accurate and comprehensive map of stable protein-protein interactions. After returning to University Medical Center Utrecht (UMC Utrecht), he obtained a VENI grant from the Dutch Science Foundation (NWO) in 2007. After starting his own research group, Patrick received an NWO VIDI award in 2012 to investigate further the molecular mechanisms underlying genetic interactions. In 2013, Patrick became an Assistant Professor at the Center for Molecular Medicine, UMC Utrecht. In addition to these research activities, Patrick has been the coordinator of the High-Performance Computing facility for Life Sciences at Utrecht Science Park since 2012 and executive committee member of the Utrecht Bioinformatics Center since 2014. Patrick joined the Princess Máxima Center for Pediatric Oncology in 2016.


The Kemmeren group uses bioinformatics and systems biology to understand the molecular mechanisms underlying genetic interactions in relation to cellular processes and complex human diseases. We have developed a unique combination of expertise in bioinformatics, gene expression profiling and molecular-genetic interactions. While our focus is on the computational aspects, we have a strong collaboration with the Holstege group, thus enabling a truly multidisciplinary approach with biochemistry, molecular biology and genetics, with bioinformatics, systems biology and functional genomics also being part of our expertise. We also have extensive experience with setting up and coordinating bioinformatics infrastructures such as High-Performance Computing, workflow management systems and data sharing and collaboration facilities.
