I 'm a research and education co-worker in the Swammerdam Institute for Life Sciences (SILS).
Since 1973 I'm working at the UVA and from 1999 in the group of Molecular Microbial Physiology which is part of the SILS.
My work is to express proteins in bacteria and the purification of these proteins. We are interested in sensors for light and study the signal generation and transduction of these proteins.
