A biologist and a businessman, he's a millionaire many many times over. He founded, and is the president of the J. Craig Venter Institute, a non-profit organisation dedicated to the advancement of genomics and its implications for society. In 2005 he co-founded Synthetic Genomics.
Venture's two main missions at the moment are to map the diversity of the microbes from environments such as oceans and town centres. His second is the attempt to create synthetic organisms.
The oceanic research filtered sea water to collect different marine micro organisms. DNA was extracted and sequenced; around 100 million letters were sequenced every 24 hours. Whenever dealing with microbes, numbers and statistics can be truly staggering. An example of how much new science Venter's project uncovered is that one barrel of sea water from one site contained 1.3 million new genes in as many as 50 000 new species.
