David Johnston
Professor of Earth and Planetary Sciences & Co-Director of Graduate Studies

In the Johnston Lab, we try to identify and pursue isotopic measurements that unlock Earth’s great mysteries, both past and present.
Dave Johnston received a BS in Environmental Studies and Philosophy from Bates College in 2002 and Ph.D. in Geology from the University of Maryland, College Park in 2007 where he worked on developing novel stable isotope systems with James Farquhar. Dave moved to Harvard as a Microbial Sciences Institute Fellow from 2007-2009 blending field geology and redox geochemistry (with Andy Knoll in EPS and OEB) with microbial physiology and experimental microbiology (with Pete Girguis in OEB). Dave joined the EPS Faculty in 2009, was promoted to Full Professor in 2016, and thinks science is a lot of fun.
