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 currently work on the European MAPPER project (www.mapper-project.eu), and I will soon 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).

My main research interests include (in arbitrary order):

Posters

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 are usually more accessible than scientific papers, here are some posters:

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.
