About Flowerree Symposium
The Flowerree Symposia provide a recurring forum to showcase Tulane University’s role in addressing climate change and its acute impacts in coastal regions such as southern Louisiana. The symposia highlight the local dimensions of a global crisis while focusing Tulane faculty, students, and community stakeholders on how the university can contribute to an evidence-based conversation about solutions. The goal is to bring together ideas and approaches that span the scientific and engineering dimensions of the climate crisis, as well as its human impacts, political challenges, and policy innovations.
2026 Overview
The 2026 Flowerree Symposium, held on October 22 on Tulane’s Uptown Campus, will bring together leading scientists, engineers, policy thinkers, and cultural scholars to examine New Orleans as a living case study in coastal risk reduction. Framed by historic floods, present-day extremes, and future environmental change, the program will explore how the Hurricane Surge Risk Reduction System (HSDRRS) is shaped by sea-level rise, storm-tide behavior, system maintenance, governance, and funding uncertainty. Sessions will also consider Hurricane Katrina’s influence on New Orleans’ musical landscape and the broader cultural dimensions of disaster, recovery, and resilience.
Special thank you to David and Jane Flowerree whose generous support made this event possible.
“We believe Tulane needs to be at the forefront of the ongoing worldwide conversation on the impact of climate change … It is our sincerest hope that the symposia will create a lasting and influential legacy by bringing together some of the brightest minds in a collaborative spirit to tackle this ever-evolving global issue.”
Featured Speakers
Sönke Dangendorf
David and Jane Flowerree Associate Professor of River-Coastal Science and Engineering, Tulane University
Sönke is an internationally recognized expert on sea-level change, coastal flooding, and climate resilience. His research combines observational data, climate and ocean modeling, and advanced statistical methods to understand the causes of past sea-level variability and improve projections of future coastal risk. He has led and contributed to major international efforts to quantify the drivers of sea-level rise and extreme water levels, with a particular focus on translating scientific discoveries into actionable information for coastal communities.
A member of NASA’s Sea Level Science Team and a contributor to assessments of the Intergovernmental Panel on Climate Change (IPCC) and state-level sea-level assessment reports in Maryland and New Jersey, Dr. Dangendorf’s work spans global climate processes while maintaining a strong emphasis on the challenges facing the Gulf Coast and Louisiana’s rapidly changing coastal landscape. His research supports decision-making on adaptation, resilience, and long-term planning in some of the world’s most vulnerable coastal regions.
Charlie Hess
President, Infrastructure and Coastal Restoration, Brown & Root Industrial Services
Charles M. Hess is a senior infrastructure executive, educator, and former federal civil works and emergency management leader with more than five decades of experience in infrastructure delivery, coastal flood risk reduction, disaster response, public works governance, and large-scale program implementation. He currently serves as President, Infrastructure and Coastal Restoration, Brown & Root Industrial Services, and is affiliated with Tulane University’s River-Coastal Science & Engineering program. His recent work has focused on coastal flood risk reduction, infrastructure adaptation, long-term resilience, governance, and the practical delivery of major public infrastructure systems. Mr. Hess previously held senior leadership positions in the U.S. Army Corps of Engineers, FEMA, and the Iraq Project and Contracting Office. His federal service included assignments in civil works, military construction, chemical demilitarization, disaster response, post-conflict reconstruction, and national infrastructure program delivery.

During hurricane Katrina recovery operations, he commanded the Corps’ emergency response forces and worked closely with CEQ, EPA, USFWS, DOT and other federal agencies as well as the State of Louisiana and local authorities. Subsequently, his main challenges in Washington were to secure necessary funds and legislation for rebuilding the Hurricane and Storm Damage Risk Reduction System, as well as developing updated national flood risk policy. Don is presently a Senior Advisor with Dawson & Associates – experts in Federal environmental policy and process, Corps’ planning and appropriations, and federal procurement strategy.
Nick Spitzer
Folklife Presenter, Educator, and Radio Producer
Nick Spitzer is an anthropologist, folklorist, media producer and professor at Tulane University whose work focuses on American vernacular culture. Throughout his career, he has documented and celebrated the local traditions, artists and communities that shape American culture, particularly those of New Orleans and French Louisiana.
Spitzer founded the Louisiana Folklife Program and helped create the Baton Rouge Blues Festival, the Folklife Pavilion at the Louisiana World Exposition and The Creole State, a long-running exhibition at the Louisiana State Capitol. His fieldwork in rural Afro-Creole Louisiana communities also contributed to important scholarship on cultural creolization, the process through which cultures interact to create new forms and meanings. He later curated programs for the Smithsonian Festival of American Folklife and produced or contributed to programming for NPR, ABC News and CBS News.
Since 1998, Spitzer has hosted and produced American Routes, a nationally syndicated public radio program exploring jazz, blues, gospel, Cajun and Creole music, country, soul and other American roots traditions. He has conducted more than 1,200 interviews with musicians and artists and carried his work in cultural diplomacy to audiences in Russia and China.

Garret Graves represented South Louisiana in the U.S. House of Representatives from 2015 to 2025, earning recognition as one of the House’s most effective lawmakers. He led bipartisan reforms involving infrastructure, energy, disaster resilience and environmental policy and chaired the Water Resources and Environment and Aviation subcommittees. As a member of House leadership, he helped negotiate major agreements involving federal spending, environmental permitting and Social Security benefits.
Before serving in Congress, Graves led Louisiana’s $20 billion effort to rebuild levees and restore coastal wetlands following Hurricane Katrina. He reorganized portions of five state agencies and helped establish a new state coastal agency. Graves also played a leading role in the Deepwater Horizon negotiations that produced the largest settlement with a single company in U.S. history.
