Professor Cheryl Kelley's Research
 

Mary Hogan of the Microbial Ecology/Biogeochemistry Research Lab at NASA Ames Research Center, CA, collecting a square of microbial mat from the Guerrero Negro salt ponds to be transported back to the greenhouse facility at NASA Ames Research Center. These mats continue to be studied because of their evolutionary link to early life on this planet, and because they can be used as an analogue to life on other planets, such as Mars, where we are now finding evidence for paleo-hypersaline environments. Prof. Cheryl Kelley is studying stable isotope compositions of the mats.
