DeFord Lecture Series

DeFord Lecture Series Speaker Schedule

The DeFord (Technical Sessions) lecture series has been a requirement and a tradition for all graduate students since the late 1940s. Once the official venue for disseminating DGS graduate student research, the DeFord Lecture series is now the forum for lectures by distinguished visitors and members of our community. Faculty and researchers from the Jackson School have invited prestigious researchers from around the world to present a lecture in this series. This is made possible only through a series of endowments.

The list below shows all scheduled talks this semester. If you would like to meet with any of the speakers, please contact them or their hosts directly.

Talks are given from 4-5PM in JGB 2.324 (Boyd Auditorium) with cookies and coffee provided around 3:30-4 PM.

Fossil network analysis and the ‘evolution’ of marine animal communities

Paleontologist and geobiologist, his work focuses on fossils of complex eukaryotes in the late Neoproterozoic-early Paleozoic interval (~1000-450 Ma) of the geologic record. By studying the paleobiology and paleoenvironments of these fossils, his work aims to understand the rise of animal life and its impact on the Earth system.
