After a mathematical M.Sc. and a Ph.D. thesis in Biology, Jerome Wojcik joined Hybrigenics, a start-up biotech company based in Paris, where he managed during 6 years the bioinformatics and IT department. He then joined Serono (now Merck Serono) in Geneva where he started managing a team of bioinformatics scientists developing algorithms adapted to genome-wide genetic association studies. The scope extended quickly to genomics and to biomarkers in general (proteomics, flow cytometry and imaging), leading to the creation of a centralized “Stratified Medicine” department within the organization, regrouping clinical project leaders, labs and bioinformatics. After 7 years of experience in the pharmaceutical industry, Jerome left his position of Director of Global Bioinformatics of Merck Serono to create Quartz Bio.
