Hope Jahren

Her book Lab Girl (2016) has been applauded as both "a personal memoir and a paean to the natural world", a literary fusion of memoir and science writing, and "a compellingly earthy narrative."

Jahren left Johns Hopkins for a full professorship at the University of Hawaii. Her research there focused on using stable isotope analysis to determine characteristics of the environment on different timescales. On September 1, 2016, Jahren became the J. Tuzo Wilson Professor at the University of Oslo's Centre for Earth Evolution and Dynamics, where she studies how living and fossil organisms are chemically linked to the environment.

Jahren earned her Ph.D in 1996 at the University of California, Berkeley in the field of soil science. Her dissertation covered the formation of biominerals in plants and used novel stable isotope methods to examine the processes. From 1996 to 1999, she was an assistant professor at the Georgia Institute of Technology, then moved to Johns Hopkins University, where she stayed until 2008.

Jahren has received three Fulbright Awards: in 1992 for geology work conducted in Norway, in 2003 for environmental science work conducted in Denmark, and in 2010 for arctic science work conducted in Norway. In 2001, Jahren won the Donath Medal, awarded by the Geological Society of America. In 2005, she was awarded the Macelwane Medal, becoming the first woman and fourth scientist overall to win both the Macelwane Medal and the Donath Medal. Jahren was profiled by Popular Science magazine in 2006 as one of its "Brilliant 10" scientists. She was a 2013 Leopold Fellow at Stanford University's Stanford Woods Institute for the Environment. In 2016, Time Magazine named her one of the world's "100 Most Influential People." Jahren was awarded Australian Society for Medical Research Medal for 2018. She was also elected to the Norwegian Academy of Science and Letters in 2018.

Anne Hope Jahren (born September 27, 1969) is an American geochemist and geobiologist at the University of Oslo in Norway, known for her work using stable isotope analysis to analyze fossil forests dating to the Eocene. She has won many prestigious awards in the field, including the James B. Macelwane Medal of the American Geophysical Union.

Jahren was born in Austin, Minnesota on September 27, 1969. Her father taught science at a community college and she has three older brothers. She completed her undergraduate education in geology at the University of Minnesota, graduating cum laude in 1991.
