About
EPSP Connects is a monthly seminar series that alternates between EPSP-related science talks and professional development panels. All events are held virtually via either Zoom, are open to all and free, and are typically held on the second or third Wednesday of the month. While we've launched EPSP Connects during the Covid 19 pandemic, we intend to continue these seminars on a monthly basis into whatever new normal emerges.
Each event requires advanced registration so we can provide a secure online environment for talks. Select science talks and panels will be made available online at the discretion of the presenters. The AGU Meeting Code of Conduct applies to this virtual meeting space . There will be zero tolerance for violations of this code. Violations will result in immediate ejection from the seminar, a filed report with AGU, and a ban from all future EPSP Connects events.
Upcoming Seminars
(All seminars at 08:00 San Francisco, 11:00 New York, 17:00 Berlin, 23:00 Beijing. In the event of confusion, Pacific Standard/Daylight Time holds, check your local time relative to PST/PDT here)
November 19th, 2025
Two Virtual Science Talks with Dr. Stephanie M. Dohner (US Naval Research Laboratory, Stennis Space Center, Mississippi) and Dr. Judy Yang (Univ. of Minnesota) themed on Exopolymeric substances (EPS) & biofilm & sediment transport.
EPS, EPS, every where: Noncohesive seabed evolution with ecosystem impacts (Dr. Stephanie M. Dohner)
Exopolymeric substances (EPS) are ubiquitous in the marine environment and are studied for their contributions to carbon sequestration, organism environmental response, trace particle capture, and much more. Less well known are the contributions of EPS in marine sediments to transport processes in noncohesive sediments when typical ecosystem and meteorological stressors occur. Here we will show a collection of work combining the impacts of EPS and bioturbation on sediment mobility and associated seabed roughness evolution during in situ and laboratory experimentation. These efforts are working towards integration of coupled, spatiotemporally varying biocohesion and bioturbation impacts on sediment transport and seabed roughness modeling while representing the ecosystem processes affecting the biota.
Multiscale Fluid, Sediment, and Biota Interactions in Aquatic Ecosystems (Dr. Judy Yang)
Addressing environmental challenges such as coastal erosion and sediment-associated pollution requires understanding the complex interactions among fluids, sediments, and biota (microbes and vegetation) across multiple scales. For instance, sediment transport at the channel scale can vary by orders of magnitude, due to micro-scale processes such as aggregation and biofilm formation. Similarly, predicting the fate and transport of sediment-associated pathogens depends on sediment-fluid-microbe interactions spanning from the micro- to macro- scale. Yet, experimental studies that span these scales remain rare. In this talk, I will describe how my group integrates microfluidic and flume experiments to investigate biofilm dynamics, sediment transport, and hyporheic exchange. Our work reveals how microbes and vegetation influence sediment stability, geomorphic evolution, and pollutant transport. These findings provide insights relevant to erosion control, water quality, and ecosystem health.

Stephanie M. Dohner is an Oceanographer with the Sediment Dynamics section at the US Naval Research Laboratory in Stennis Space Center, Mississippi. Her work focuses on interdisciplinary approaches to sediment transport and near-bed processes from
coastal systems to the deep sea, with interests in sensor development and autonomous systems. She received her PhD in Oceanography from the University of Delaware (2020), focusing on storm impacts to coastal sediment processes.
Judy Yang is an Assistant Professor in Civil, Environmental, and Geo-Engineering at the University of Minnesota. She earned her Ph.D. from MIT (2018) and was a postdoctoral researcher at Princeton (2018-2020). Her research uses microfluidics and flume experiments to understand how microbes and vegetation control coastal erosion and water quality. She has received the NSF CAREER Award and serves as Associate Editor for Water Resources Research.
