Project Summary This application requests funds to support the 14th Gordon Research Conference on Environmental Endocrine Disruptors (GRC-EED), to be held June 23-28, 2024 and the accompanying Gordon Research Symposium (GRS) for trainees, to be held June 22-23, 2024 at the Renaissance Tuscany Il Ciocco Resort in Barga, Italy. The conference theme is The role of EEDs in planetary health and planetary boundaries and the unifying goal of the conference is to present cutting-edge results, illustrating the depth and breadth of work being done to study EEDs, in a way that is accessible across disciplines and beyond the boundaries of science. The GRC-EED will have 9 sessions: The first session will have two keynote talks focused on a high- level view of human exposures to EEDs and their health consequences. Next, there will be scientific sessions, each focused around a broad topic such as “Mechanisms of EED Action”, “Characterizing human exposure to EEDs”, “Breaking down the walls between human and experimental toxicology” and “Enhancing interdisciplinary and multistakeholder collaboration in the EED field”. The final session will highlight “big picture” issues related to “Planetary Health: Global Solutions for Global Problems”. The GRC-EED will also include two poster sessions, and speakers will be selected from the submitted abstracts to also give short talks. Prior to the GRC-EED, the GRS will provide an outstanding, intimate setting with opportunities for trainees to network and present their work in a supportive environment. The GRS will include a keynote speaker and a discussion panel with four members representing different career paths (government, industry, academia and non-profits) and additional speakers will be selected from trainee abstracts. The GRC-EED and GRS are intended to have presentations by leading scientists highlighting new information from researchers who work across several disciplines including toxicology, endocrinology, neuroscience, exposure science, public health, ecology, physiology, and epidemiology, among others. The conference has been organized to integrate these various fields throughout the meeting to permit open and informative discussions, introduce new paradigms and lead the field forward towards novel discoveries. The GRC represents a unique venue for promoting the exchange of scientific ideas through its format of extensive discussion periods in each session, ample free time to encourage informal interactions, and exchanges at poster sessions that will allow attendees to present their latest research findings in a collegial atmosphere.
