Johan Westerhuis studied Analytical Chemistry/Chemometrics at the Rijks Hogeschool Groningen where he received his BSc degree in 1989. He then went to the Catholic University of Nijmegen to study Chemistry/Chemometrics in the group of Dr. L.M.C. Buydens, where he received his MSc degree in 1992. From 1992-1997 he worked towards a PhD at the University Centre for Pharmacy at the University of Groningen on Multivariate Statistical Modeling of the Pharmaceutical Process of Wet Granulation and Tableting. From 1997 until 1998 he worked as a postdoctoral researcher at the McMaster University, Hamilton, ON, Canada together with Dr. JF MacGregor. In October 1998 he joined the former Process Analysis & Chemometrics group, now the Biosystems Data Analysis group at the University of Amsterdam. Since 2012 he also has an extraordinary professor position at the North West university in Potchefstroom, South Africa. Johan is the Eastern Analytical Symposium 2010 Award Recipient for Achievements in Chemometrics. Both in 2013 and 2014 he received the best paper award of the Metabolomics Journal. Furthermore, in 2014 he received the highest download award of the same journal.
The current research focuses on the development of methods for the analysis of complex data obtained from metabolomics studies. In another project he developed feature selection methods in case of many below detection limit values, a known problem in metabolomics data. Finally, summarizing gene expression data by mapping on gene sets could help closing the gap between different platform gene expression data.
