Many congratulations to Dr Sasha Turchyn who is the recipient of the 2021 R. Berner Lectureship. The Lectureship, which will be presented at the Goldschmidt 2021 conference, is awarded to scientists who show an 'exceptional ability to define globally important biogeochemical processes, develop new understanding, and significantly advance the corresponding area of research'.

Sasha is a Reader in Biogeochemistry at Cambridge Earth Sciences, and works at the interface between geochemistry and (micro)biology to understand how microbial populations such as bacteria and archaea influence the carbon cycle.


The lecture was established in 2017 by students and friends of the late Robert Berner to commemorate his intellectual legacy in geochemistry. It is a joint program of the Geochemical Society and the European Association of Geochemistry, presented as an annual lecture at the Goldschmidt Conference.

The lecture is on a ‘Berner’ subject, which includes a wide range of topics associated with elemental cycling at the Earth’s surface (molecular to planetary scale, modern to ancient oceanic and terrestrial systems, evolution of the biosphere, etc).

“Bob Berner is a personal scientific hero of mine; his was the textbook of the first course I ever took in Geochemistry" said Sasha, "To be giving a lecture named after him is a complete honor. I reference his work all the time, and am always amazed at how he figured out so many fundamental principles so early on.”

Lecturers are distinguished and outstanding mid-career scientists, selected by the Berner Lecture Committee, then approved by the Geochemical Society and the European Association of Geochemistry.
