Jeroen Jansen has studied chemistry at the University of Amsterdam, with a specialization in Chemical Engineering. He started his PhD with Age Smilde at the Process Analysis and Chemometrics groupm and was one of the first to develop chemometrics specifically for metabolomics and other high-dimensional systems biology. His thesis introduced Analysis of Variance-Simultaneous Component Analysis (ASCA), by now a widely used chemometric method. His first Post-Doc was at the Netherlands Institute for Ecology, where he studied the application of metabolomics technology in the study of plant-insect interactions. After almost four years of dirty hands, Jansen went back to the computer desk at the Netherlands Metabolomics Centre. He there further developed methods specifically for the study of Individual Differences, very relevant in Personalized Health. Since 2011, Jansen is Assistant Professor in the Chemometrics department of Lutgarde Buydens at the Radboud University in Nijmegen, the Netherlands. He has been Head of Department there since 2016. Jansen leads a group of enthusiastic young researchers in the development of chemometric solutions for MSPC, in industry, medical diagnostics and environmental analysis.
- What is your relation to chemometrics? (Active, newcomer, etc.)
I have been working all my academic career in chemometrics (since around 2000). When I did not work in chemometrics (in chemical ecology) I found out that I could not do without it, and that there was a huge demand in such expertise in that field.
- What are your favourite methods of data analysis, and why?
I feel that I cannot do without mentioning ASCA, but I think the biplot brings by far the most added value to a data analysis in terms of systemic insight. Thirdly, I am always amazed that MCR (when you are lucky) just resolves the constituents of a mixture with very minor amounts of prior knowledge.
- How do you see the future of chemometrics?
Chemometrics has a strong added value to AI, Data Science and Machine Learning in that it is strongly integrative. Much of the added value of chemometrics solutions come from a proper quantitative understanding of the analytical platform used to collect the data, for example in data preprocessing and in informed constraints imposed in MCR. The measured system on the other hand may be reflected in Design-of-Experiments and other methods. The future of chemometrics to me is adhering to this integrative aspect, using this to better formulate value propositions for the chemometrics solutions we develop.
- What do you look forward to at SSC16?
Seeing interesting implementations of chemometrics for sustainability, quality of life and other interesting benefit to mankind!
