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 the 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 3:45-4:50PM in JGB 2.324 (Boyd Auditorium) with cookies and coffee provided around 3:20-3:30 PM.

Apr. 16 Beata Csatho

University of Buffalo

Monitoring ice sheet mass balance and ice dynamics to understand ongoing rapid cryospheric changes; combining geophysical, remote sensing, climate and glaciological observations to understand the linkages between subglacial geology and ice sheet dynamics; reconstructing cryospheric changes from historical observations; developing new methods for change detection, data fusion and visualization to support Earth science applications.
