Warren Distinguished Lecture Series

Banners that illustrate CEGE's mission and vision hang in the Charles Fairhurst Rotunda

The Warren Distinguished Lecture Series was made possible through a generous, renewing gift from Alice Warren Gaarden. CEGE is continually thankful for her generosity, which allows us to bring in researchers and practitioners to share their knowledge with students, faculty, and friends of CEGE. A lecture is held most Fridays (September to May) at 10:10 a.m. in the George J. Schroepfer Conference Theatre (room 210) in the Civil Engineering Building. 

If you cannot join us in person, please join us online. Registration is required. After registering, you will receive a confirmation email containing information about joining the meetings.

Past Events

Entrainment and Transport of Sand and Tailings along the Paraopeba River, after the Collapse of a Tailings Dam, Minas Gerais, Brazil

A Warren Distinguished Lecture with
Marcelo H. Garcia, PhD, NAE

Civil and Environmental Engineering
University of Illinois at Urbana-Champaign
 
In this presentation, Marcelo Garcia discusses some of the tools needed to assess the spatial-temporal evolution of tailings discharged into a river following a dam breach. 

Human-Automated Vehicle Interactions: Voluntary Driver Intervention in Car-following

A Warren Distinguished Lecture with
Soyoung (Sue) Ahn

Civil and Environmental Engineering
University of Wisconsin-Madison
 
Soyoung (Sue) Ahn's research is concerned with the behavior of voluntary driver interventions in automated vehicles in car-following, initiated by the driver in non-safety-critical situations rather than by the system. Specifically, the study she discusses analyzes the dynamic process of voluntary driver intervention through evidence accumulation (EA) modeling, which describes the evolution of the driver's distrust in automation, ultimately resulting in intervention. 

Computational Framework for Extreme System Responses

A Warren Distinguished Lecture with
Mircea Grigoriu

Civil and Environmental Engineering
Center for Applied Mathematics
Cornell University

ONLINE ONLY
In this talk, Mircea Grigoriu develops a practical method for estimating the distribution of extreme solutions of stochastic problems. The first part of the presentation reviews essential concepts of probability theory and illustrates the need for uncertainty quantification in engineering via simple examples. The second part presents the computational framework for estimating extremes of random processes.

Evaluating and Managing the Financial Risks of Extreme Environmental Events

A Warren Distinguished Lecture with
Greg Characklis

Environmental Sciences and Engineering
University of North Carolina at Chapel Hill

This discussion revolves around describing approaches to characterizing financial risk in coupled natural-engineered-economic systems, followed by a description of several recent studies. Examples include evaluating strategies for managing the financial risk of environmental extremes on economic sectors such as urban water utilities, electric power utilities, inland navigation and the housing market.

Seismic Stability and Resilience in Steel Buildings

A Warren Distinguished Lecture
and Dexter Lecture with
Larry Fahnestock

Civil and Environmental Engineering
University of Illinois Urbana-Champaign

Larry Fahnestock explores foundational seismic stability principles and inelastic earthquake response using results from large-scale tests and numerical earthquake simulations of steel building systems. The results demonstrate that high-ductility response is an insufficient, and not always necessary, condition for seismic stability, and that the most critical parameter for seismic stability and resilience is persistent secondary stiffness. He discusses a pragmatic approach for incorporating secondary stiffness into seismic design.

Old Dog, New Tricks: Engineering Microorganisms for Environmental Release, Remediation, and Risk Assessment

A Warren Distinguished Lecture with
Cresten Mansfeldt

Civil, Environmental, and Architectural Engineering
University of Colorado Boulder
 
In this talk, Cresten Mansfeldt focuses on understanding the potential benefits of and solutions to tracking engineered microorganisms designed for environment release (EMERs). Mansfeldt discusses new general molecular biology tracking methods and computational techniques in terms of a case study of applying new approaches to post-wildfire contamination management.

Getting More out of Engineered Microbial Bioprocesses for Resource Recovery

A Warren Distinguished Lecture with 
Ryan Ziels

Civil Engineering
University of British Columbia Vancouver

Ziels presents about several methodological developments in molecular biology approaches and their application to biological water treatment systems. Taken together, these new approaches provide a path forward for developing sound engineering strategies to manage microbiomes for circular resource recovery from waste materials.

Toward Economic and Seismic-Safe Geologic Hydrogen

A Warren Distinguished Lecture with
Mengsu Hu

Energy Geosciences Division
Lawrence Berkeley National Laboratory

In this talk, Mengsu Hu shares state-of-the-art research that combines laboratory experiments with numerical modeling to predict and control H2 generation and extraction more effectively. This presentation underscores the economic potential of geologic hydrogen, identifies key areas where interdisciplinary research is most needed, and outlines future pathways toward the success of geologic hydrogen.

CEGE Three-Minute Thesis Contest

Doctoral students in CEGE compete to describe their research in just three minutes. They must use language accessible to non-expert audiences and just one slide. It's a big challenge! Tune in to see how they do!

Large-Scale Coastal Morphodynamics and Anthromorphodynamics

A Warren Distinguished Lecture with 
Brad Murray

Geomorphology and Coastal Processes
Duke University

Murray reviews the wave- and sediment-transport dynamics that shape coastlines over timescales of years to millennia, and how coastline plan-view shapes respond to variations in wave (storm) climate, and describes the sea-level-rise and storm processes that build and tend to maintain barrier islands on low-slope coastlines.
