Marc is founder and CSO of Tagworks, a pioneer of in vivo click chemistry, and the inventor of the now widely used Click-to-Release approach for improved systemic therapies. He spun the technology out of Philips Healthcare and then drove its development into a broadly applicable platform technology for systemic therapies, while building a broad IP estate, productive partnerships, and a strong team and blue-chip investor base. At Philips Marc worked on molecular imaging and drug delivery programs, eventually focusing on in vivo click chemistry applications in these domains. Prior to Philips, he worked at Kreatech Diagnostics on the development of probes for microarray-based detection of DNA, RNA and proteins. In addition, he was a visiting scientist at the School of Biotechnology and Biomolecular Sciences, University of New South Wales, Sydney. Marc obtained his MSc and PhD in bio(in)organic chemistry at, respectively, the University of Groningen and the Leiden Institute of Chemistry, The Netherlands. He has published 41 peer-reviewed papers and is a co-inventor on 22 patents.
