November 14, 2025 – Ken Kamrin, UC Berkeley
Speaker/Affiliation: Ken Kamrin, UC Berkeley Title: Continuum modeling and simulation of dry and saturated granular media across applications Time: Friday, November 14 12:00pm PST Location: EMS B210Abstract: Granular media are common in industry, the natural world, and our day-to-day lives, but have been historically resistant to modeling. While grain-by-grain discrete element methods (DEM) exist, these are often far too costly at…

November 12, 2025 – Pulkit Singh, Stanford University
Speaker/Affiliation: Pulkit Singh, Stanford University Title: The rise and fall of carbonate skeletons Time: Wednesday, November 12 12:00pm PST Location: EMS B210Abstract: Mineralized skeletons revolutionized marine ecosystems, yet their long-term biomass history has remained poorly constrained. We compiled data from ~7,400 carbonate thin sections spanning 540 million years to reconstruct proportional skeletal biomass produced by skeleton forming organisms across geologic time. The…

November 19, 2025 – Ching-Yao Lai, Stanford University
Speaker/Affiliation: Ching-Yao Lai, Stanford University Title: Changing ice in a warming climate: a data-driven approach Time: Wednesday, November 19 12:00pm PST Location: EMS B210Abstract: One of the greatest uncertainties in sea-level rise projections arises from our incomplete understanding of how ice sheets would lose mass in a warming climate. In this talk, I will discuss two poorly understood aspects of ice…

November 7, 2025 – Debanjan Sengupta, New Mexico State University
Speaker/Affiliation: Debanjan Sengupta, New Mexico State University Title: Pathway to the Formation of Planetesimals in Early Solar Nebula by Turbulent Concentration Time: Friday, November 7 12:00pm PST Location: EMS B210Abstract: The formation of planets was shaped by the formation of the first large planetesimals in the protoplanetary nebula. Moreover, the properties of primitive meteorites derived from these planetesimals provide our only ground…
