About our Research
For decades, geomicrobiologists have used lipid compounds preserved in rock and sediment to make predictions about early life and the conditions on ancient Earth. We study these molecular biomarkers in modern organisms to refine our interpretations of the microbial fossil record.
About our Lab Community
We are an interdisciplinary lab, and our research benefits from having a team of scientists with diverse backgrounds (racial, gender, ethnicity, sexual-orientation, country of origin, etc.). We believe in nontraditional paths to careers in STEM, recognize structural inequity in academia, and actively support Black Lives Matter.
Navigating the Academic Path as a First-Gen Latina Scientist
Watch Dr. Paula Welander trace her path in academia. This event is part of the #Stanford Earth Celebrates series honoring Latinx heritage month and the contributions of the Hispanic and Latinx community in the Earth and Environmental sciences.
Q&A: What does it mean to be Latinx in the geosciences?
Stanford Earth recently transitioned the Office of Multicultural Affairs (OMA) into its new Diversity, Equity, and Inclusion (DEI) initiative. As part an effort to celebrate and discuss identity, six Stanford Earth members share how their ethnic-cultural backgrounds have informed and impacted their careers.
Overlooked process in bacteria may shed light on ancient environments
Geologists assume when they find molecules called sterols in soils or rocks they indicate the presence of plants, animals or fungi in ancient environments. But discovering how some bacteria also produce and modify sterols could change those interpretations.
