The Smithsonian’s MarineGEO program, based at the Smithsonian Environmental Research Center in Edgewater, Maryland, seeks a postdoctoral scholar to advance a new research project focusing on trait-based analyses of climate vulnerability and functional change in marine ecological communities of the Florida Reef Tract. The project involves standardized field surveys of reef fish and invertebrate communities across 74 sites, funded by the EPA South Florida Program, and leverages a wealth of complementary data from the long-running benthic survey time series at the same reef sites, from the Dry Tortugas in the south to Martin County in the north, led by the Coral Reef Evaluation and Monitoring Program (CREMP) and SECREMP. The candidate will lead a team conducting intensive surveys of fishes and mobile macroinvertebrates using globally recognized Reef Life Survey protocols. The Postdoc will work with PIs Emmett Duffy (Smithsonian), Leah Harper (Smithsonian), Rob Ruzicka (Florida Fish & Wildlife Conservation Commission and CREMP), and Dave Gilliam (Nova Southeastern University and SECREMP).

Research Context: This project seeks to understand and build predictive models of the influence of accelerating anthropogenic change on reef biodiversity and community structure, and to provide a key baseline and predictive foundation for informing management responses to stressors related to climate warming, reef structural simplification, and fishing. As part of this project, we are censusing fishes and mobile macroinvertebrates at all 74 CREMP and SECREMP sites in 2024 and 2025, and assembling an unprecedented database of co-located coral, fish, and invertebrate community structure surveys, water temperature readings, and reef physical structure measurements that will be analyzed to understand ecosystem change across the Florida Reef Tract.

Research Environment: The postdoc will be based in Emmett Duffy’s group in the MarineGEO program at the Smithsonian Environmental Research Center in Edgewater, Maryland, but will work closely with the Co-PIs and a diverse group of experts in marine science and coral reef ecology in Florida. The postdoc will also have opportunities to participate in MarineGEO network-wide activities.

Responsibilities and Duties: The postdoc will be a key member of the project team, co-leading organization of and participating in fieldwork (primarily in Summer 2025), as well as data collation, synthesis, and the writing of peer-reviewed manuscripts. The postdoc will attend and present results of the research at conferences. We especially welcome applicants with a strong2background in quantitative marine biology or ecology, particularly related to coral reefs. Research activities include diver visual surveys of coral reef fishes and invertebrates, statistical analysis and modeling of data linking environmental drivers to biodiversity and community structure, literature data mining, and potentially meta-analysis. The postdoc will have opportunities to build skills including big data management and analysis, team science coordination, and community engagement.

Basic Requirements:

• Doctoral degree in a relevant field of natural, social, or interdisciplinary sciences.
• Demonstrated skills in one or more of the following: marine ecology, quantitativeecology, coral reef ecology.
• Ability to plan, execute, communicate, and publish independent and collaborativeresearch.
• Strong quantitative spatial and coding skills (e.g., Python, R, GIS).
• Eagerness to learn from and work with a diverse, interdisciplinary community.
• AAUS-certified scientific diver (current active diver status strongly preferred).

Desired Qualifications:

• Strong track record of lead-authored scientific publications.
• Experience quantifying, mapping, and analyzing data on biodiversity, communitystructure, and climate-mediated ecological change.
• Knowledge of West Atlantic reef fishes and experience with in situ fish visual census.

Appointment & Application: The appointment is for up to 2.5 years (renewable after each year pending satisfactory progress) as a Smithsonian Trust employee at the IS-9 level, with a competitive salary, paid leave, health, vision, dental, and other benefits. Proof of authorization to work in the U.S. is required, but international applicants are welcome. This is not a federal position.
