Lennart Martens is Full Professor of Systems Biology at Ghent University, Group Leader of the Computational Omics and Systems Biology (CompOmics) group at VIB, and Associate Director of the VIB-UGent Center for Medical Biotechnology, all in Ghent, Belgium. He also holds a Visiting Group Leader position at EMBL-EBI in Cambridge, UK. He has been working in proteomics bioinformatics since his Master’s degree, which focused on the computational interpretation of peptide mass spectra, and the sequence-dependent fragmentation of peptides. He then worked as a software developer and framework architect for a software company for a few years, before returning to Ghent University to pursue a Ph.D. focused on proteomics and proteomics informatics. During this time, he worked on the development of high-throughput peptide centric proteomics techniques and on bioinformatics tools to support these new approaches. In 2003 he started the PRIDE proteomics database at the EBI as a Marie Curie fellow of the European Commission. After obtaining his Ph.D., he rejoined the PRIDE group at EBI, which he coordinated for several years before moving back to Ghent University to take up his current position. Prof. Martens has been elected to the Young Academy of the Royal Belgian Academy of Sciences in 2013, to the Human Proteome Organisation (HUPO) Council in 2016, has been elected Vice-President of the European Proteomics Association in 2017, and was admitted as Fellow of the Royal Society for Chemistry in 2018. He also served on the HUPO Executive Board from 2017 to 2019. Dr. Martens received the 2014 Prometheus Award for Research Excellence from Ghent University, and the 2015 ‘Juan Pablo Albar’ Proteomics Pioneer Award from the European Proteomics Association. An author on more than 220 peer-reviewed papers, he has also co-written two popular Wiley textbooks on computational mass spectrometry.
