Han (J.G.E.) Gardeniers obtained a MSc degree in chemistry and a PhD in experimental solid-state physics from Radboud University Nijmegen, The Netherlands, in 1985 and 1990, respectively. He joined the University of Twente in 1990 and was a visiting researcher at Carnegie Mellon University (Pittsburgh PA, USA) and University College of London during the years 1994-1995. From 2001 till 2003 he worked as a senior scientist at Kymata Ltd./Alcatel Optronics and Micronit Microfluidics, after which he rejoined the University of Twente in the Biosensors/Lab-on-a-Chip Group. In 2007 he started his research group "Mesoscale Chemical Systems", which focuses on micro and nanostructures for chemical applications, including microreactors and microfluidic systems for chemical analysis. He teaches topics in Nanotechnology and Chemical Science & Engineering. He received an NWO Vici grant in 2004 and an ERC Advanced Grant in 2017, co-authored over 300 reviewed journal papers and was co-inventor on 11 patents.
