Ken Cullings received his PhD in the Bruns Lab in December of 1993. He then worked as a postdoc for the USDA in Corvallis Oregon. Ken returned to the bay area at the end of 1994 and worked with Christian Orrego and Tom Parker at San Francisco State University in the Conservation Genetic Laboratory until May of 1997.
In January of 1998, Ken started working as a Scientist in the
Branch of NASA-Ames Research Center in Mountain View, a permanent pure research position. He's the token biologist in Exobiology, everyone else being planetary physicists, geologists and chemists.

Moffett Field, CA 94035-1000
His current projects are:
- PI on the NSF project looking at effects of above-ground
manipulations to carbon and soil chemistry on EM community structure.
- Co-PI and chief evolutionary ecologist at NASA on the Early
Microbial Ecosystems study looking at ecology and evolution in
systems that match or nearly match earth's earliest ecosystems.
- Evolution of major lineages of snakes and rates of molecular
evolution in squamate nuclear and mitochondrial genomes.
