Derek Groen, CCS, Chemistry Department, University College London

Welcome to the webpage about me, Derek Groen. I am an interdisciplinary computational researcher working in the Centre for Computational Science at UCL. I'm currently a Fellow of 2020 Science ( and I recently worked on the European CRESTA project ( and the MAPPER project ( In addition, I am a Fellow of the Software Sustainability Institute

My main research interests include (in arbitrary order):
