Welcome to the webpage about me, Derek Groen. I am an interdisciplinary computational researcher working in the Centre for Computational Science at UCL. I currently work on the European CRESTA project (www.cresta-project.eu) and have worked on the MAPPER project in the recent past (www.mapper-project.eu). In the near future I will work on the CER2EBRAL project in collaboration with several institutes in Qatar. In addition, I am an Associate Fellow of 2020 Science (www.2020science.net) and a Fellow of the Software Sustainability Institute www.software.ac.uk.
My main research interests include (in arbitrary order):

Interview by the Independent on cerebrovascular bloodflow with HemeLB: Computer simulation could become integral in the diagnosis, treatment, or preventation of disease by the end of the century.
Interview by International Science Grid This Week (isgtw.org) on just about anything I've been involved with recently: Blood flow in the brain, multi-scale modeling, and more. life as an early-career HPC researcher.
Article on MUSCLE in HPCWide: Adding MUSCLE to Multiscale Simulations.
MAPPER: Flexible composition and execution of high performance, high

Papers tend to be written with the intent to be read by other scientists, and might not be very useful for people without a similar background. Because poster presentations and slide sets are usually more accessible than scientific papers, here are a few of them:
1. Multiscale Computing with HemeLB (coupling
simulations of human bloodflow)
2. Simulating star clusters on a global grid of PCs with GRAPE hardware
3. Simulating the Universe across two supercomputers, one in Amsterdam and one in Tokyo
4. Simulating the Universe across a planet-wide network of up to four supercomputers
5. A light-weight communication library for distributed computing
All of the posters relate directly to a journal article, so if you would like to know more feel free to check the papers. And if your thirst for knowledge on these topics is still insufficiently quenched after that, do not hesitate to contact me directly.
If you are interested about all my other publications, then I would recommend to take a look at my Google Scholar page.
