What are Trust Fund Positions?
Trust Fund positions are unique to the Smithsonian. They are paid for from a variety of sources, including the Smithsonian endowment, revenue from our business activities, donations, grants and contracts. Trust employees are not part of the civil service, nor does trust fund employment lead to Federal status. The salary ranges for trust positions are generally the same as for federal positions and in many cases trust and federal employees work side by side. Trust employees have their own benefit program, which may include Health, Dental & Vision Insurance, Life Insurance, Transit/Commuter Benefits, Accidental Death and Dismemberment Insurance, Annual and Sick Leave, Family Friendly Leave, 403b Retirement Plan, Discounts for Smithsonian Memberships, Museum Stores and Restaurants, Credit Union, Smithsonian Early Enrichment Center (Child Care), Flexible Spending Account (Health & Dependent Care).

Smithsonian Environmental Research Center (SERC), Office of the Under Secretary for Science and Research (OUSSR), Smithsonian Institution is a research unit of the Smithsonian Institution dedicated to ecological research and education.

SERC’s 2,650-acre campus serves as a living laboratory for long-term ecosystem research across forests, farmland, wetlands, shorelines, and estuaries. Located within a rural landscape yet adjacent to the Baltimore–Washington–Annapolis urban corridor on the Chesapeake Bay, SERC occupies a central position within the Bay’s watershed. Our community of approximately 150 staff—including principal investigators, educators, technicians, postdocs, and student researchers—collaborates annually with interns, more than 500 volunteers, and 25,000 public visitors.

SERC’s research and education programs address major environmental challenges identified in the Smithsonian’s Life on a Sustainable Planet initiative. Our work spans ecological scales, leverages long-term studies, and delivers benefits for ecosystems and society. We collaborate widely and prioritize public engagement through participatory science, education, and communication

This position reports to the Associate Director for Research, serves as a Principal Investigator, and leads an independent research program at SERC. The ideal candidate will collaborate effectively with a diverse community of staff, students, volunteers, visitors, and partners to develop a high-impact research program.

The selected applicant will have access to extensive field, laboratory, and data resources at SERC, with opportunities to expand these assets, including a potential agrivoltaic research facility. Existing resources include over five decades of watershed research with instrumented experimental watersheds, a watershed-scale stream restoration project, and large biodiversity–ecosystem function agroforestry experiments (BiodiversiTREE and Functional Forests). Additional assets include a NEON site, a ForestGEO plot, the TEMPEST coastal forest experiment, and the Global Change Research Wetland (GCReW), which supports in situ studies of biogeochemical responses to global change.

SERC also offers advanced analytical instrumentation and computing infrastructure for geospatial analysis, modeling, and statistical research. The position benefits from access to broader Smithsonian resources, including expertise across multiple science units such as Smithsonian Tropical Research Institute (STRI) and Smithsonian’s National Zoo and Conservation Biology Institute (NZCBI).

The Smithsonian Environmental Research Center (SERC) seeking qualified candidates for a Sustainable Agriculture Physical Scientist position with expertise in system-level research in fields such as agroecology, sustainable agriculture, forestry and related topics.

Our goal is to establish a research program that addresses key agricultural sustainability challenges—spanning agrivoltaics, regenerative practices, forestry, soil and nutrient management, and water systems—through an integrated, systems-level framework across ecological, technological, economic, and social domains. We also anticipate that the research program will use SERC as a model landscape and conduct comparative studies across other local, regional, and global sites as appropriate. The research is highly innovative, encompassing multiple distinct and complex thematic areas.
  • Expertise in physical science disciplines (e.g., soil chemistry, soil physics, geochemistry, biogeochemistry, or hydrology) and experience conducting research in both field and laboratory settings related to agroecology, sustainable agriculture, forestry, and allied areas (see qualification requirements).
  • Build and strengthen strategic partnerships with research institutions, organizations, and the public to support and advance program goals.
  • Examines the physical and chemical properties of environmental media (e.g., air, water, soil, and sediments), including nutrient fate and transport, thermodynamics, fluid dynamics, and chemical transformations. These processes underpin understanding of environmental system function, pollutant behavior, and the measurement, modeling, and assessment of environmental conditions. Although the work supports environmental outcomes, it primarily emphasizes the quantitative analysis and modeling of physical and chemical processes rather than biological or ecological systems.
  • Knowledge of research design, planning, and implementation for investigating ecological processes in field and laboratory settings.
  • This research program addresses critical challenges through the integrated use of field and laboratory studies, instrumentation, sensors, and computational tools to produce ecological and environmental data aligned with SERC themes. The work requires significant independence and judgment in determining research priorities and approaches.
  • Develops innovative and competitive research proposals that support program goals and advance research priorities. Identifies and pursues promising research opportunities aligned with agency needs and the current state of the science.
  • Responds to funding opportunities from both internal SI sources and diverse external sponsors, including federal agencies (e.g., U.S. Coast Guard, NOAA, U.S. Geological Survey, National Science Foundation), state natural resource agencies, non-governmental organizations, private foundations, and international entities.
  • Coordinates proposal development with the Smithsonian Office of Sponsored Projects and SERC leadership. Prepares and manages budgets covering research travel, supplies, equipment, and personnel.
  • Develops position descriptions and secures funding to support staffing needs associated with funded projects. May serve as principal investigator and/or co-investigator on multiple proposals and projects.
  • Prepares reports and delivers presentations summarizing research findings, network accomplishments, and program outcomes.
  • Disseminates methods, results, and impacts through digital and virtual platforms.
  • Publishes and communicates original and applied research on ecological and physical processes, drawing on disciplines such as chemistry, physics, geochemistry, hydrology, and atmospheric science to evaluate environmental conditions in field and laboratory settings.
  • Communications are informed by the analysis and interpretation of complex experimental, long-term, and large-scale datasets and align with the program’s overall research goals and objectives. Authors and disseminates findings to advance understanding of research techniques and ecological processes.
