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 4:00-5:00PM in JGB 2.324 (Boyd Auditorium) with cookies and coffee provided around 3:20-3:30 PM.

Redox Revolutions on Earth and Beyond

Scientist and educator interested in Earth’s evolution as an inhabited world, and the prospects for life beyond. His major focus is the deep time history of O2 and bioessential metals in the oceans, as deduced from the application of novel techniques in isotope geochemistry to ancient sedimentary rocks.

Mark Raizen (Physics)

Edwin Allday Lectureship in Geological Sciences
Apr. 9 Andres Folguera

Universidad de Buenos Aires

Integrates continental tectonics with volcanology, plate reconstructions, and marine geophysics. Brian Horton Edwin Allday Lectureship in Geological Sciences
Apr. 14 Daniel Penny

The University of Sydney, Australia

Environmental histories; global tropics, particularly mainland Southeast Asia and Central America, through to Australian based environmental reconstructions. Application of palaeo-botany and sedimentology to document the response of ecosystems to climatic variability and human activities over long periods of time. The response of human communities to environmental change. Tim Shanahan N/A
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.

Looking deeper: role of sub-soils in Organic Matter Dynamics

Soil science and global change science; understand the effect of changing environmental conditions on vital soil processes, most importantly the cycling and fate of essential elements in the critical zone

Michael Young The Fred L. and Frances J. Oliver Lectureship in Texas Hydrology and Water Resources
Apr. 30 Sonia Seneviratne

ETH Zurich

Analyzes climate extremes, land-climate processes, and climate changes. She uses several methods and approaches for these investigations: modeling (climate modeling, land surface modeling), data analysis (based on observations, reanalysis data, model simulations, satellite data), new approaches for the derivation of validation datasets, and own field experiments. Zong-Liang Yang The Judd H. and Cynthia S. Oualline Centennial Lecturer in Geological Sciences
May 7 Jennifer McIntosh

University of Arizona

Elemental and isotopic chemistry of surface waters, groundwaters, saline fluids, and natural gas to better constrain the sources of solutes, residence times and flow paths of fluids and gas, and biogeochemical processes. Research involves extensive field sampling, laboratory analyses, and geochemical and hydrologic modeling. Bayani Cardenas The Fred L. and Frances J. Oliver Lectureship in Texas Hydrology and Water Resources
