Fischer is recognized by the global Earth and space sciences community for her tremendous efforts and dedication to advancing Earth and space sciences. 

The Lehmann Medal is named in honor of Inge Lehmann, who made many contributions to our understanding of the Earth’s deep interior, including her discovery of the Earth’s inner core in 1936.  Lehmann served for 25 years as the first chief of the seismology department of the Royal Danish Geodetic Institute and was a former president of the European Seismological Federation, the Danish Geophysical Society, and vice president of the International Association of Seismology and Physics of the Earth’s Interior.

Fischer is the  Louis and Elizabeth Scherck Distinguished Professor of Geological Sciences and Director of Undergraduate Studies for Brown’s Department of Earth, Environmental and Planetary Studies. Her research focuses on understanding the lithosphere and asthenosphere, how these layers are created and evolve over time, and their roles in plate tectonics and mantle convection. 

Fischer joins other scientists, leaders, educators, journalists, and communicators from around the world who have made outstanding achievements and contributions by pushing forward the frontiers of science. Each recipient embodies the AGU’s community’s shared vision of a thriving, sustainable, and equitable future powered by discovery, innovation, and action.  These recipients have worked with integrity, respect, and collaboration while creating deep engagement in education, diversity, and outreach.

AGU will formally recognize this year’s recipients at AGU23, which will convene more than 25,000 attendees from over 100 countries in San Francisco and online everywhere on 11-15 December 2023. This celebration is a chance for AGU’s community to recognize the outstanding work of our colleagues and be inspired by their accomplishments and stories.
