Darlene is a geobiologist and limnologist (and yes, her last name is Lim) based at the NASA Ames Research Center. Her research interests span Earth and Space Science.
She is the PI of the Pavilion Lake Research Project (PLRP; http://supercritical.civil.ubc.ca/~pavilion/), which is investigating the potentially unique microbialites found in this lake.
Her research interests at Pavilion Lake include its chemical and biological limnological characterization, and the isotopic biosignatures associated with the microbialites. Darlene also conducts limnological and paleolimnological investigations of remote lakes and ponds in the Canadian High Arctic to characterize Holocene climate change. She has also extrapolated her Arctic work to Mars analogue paleolake reconstructions.
Since 1999, she has been participating in the NASA/SETI Haughton Mars Project, and was selected to inhabit the Mars Society's Flashline Mars Arctic Research Station (FMARS), the world's first Mars simulation base, at Haughton Crater in 2000 and 2001.
Over the past decade, Darlene conducted fieldwork in the Canadian High Arctic, the Antarctic, throughout Central America, Guyana, U.S., Canada, and Chile. She continues to ardently promote the importance of science and exploration through lectures, media outreach and editorial contributions.
