Opportunity Summary:

The Environmental Protection Agency (EPA) issued this funding opportunity through its Science to Achieve Results (STAR) Research Program to support the creation of computational toxicology research capacity focused on developmental toxicity. The central goal is to fund a research center (or equivalent coordinated effort) that can build and validate in vitro (cell-based or biochemical) and in silico (computational) models that describe and predict how environmental pollutants and toxicants can disrupt biological pathways involved in normal development. The emphasis is on moving beyond isolated assay results toward models that connect measurable molecular and cellular responses to real developmental outcomes, ultimately improving the ability to anticipate risk from developmental exposures.

A key feature of the solicitation is integration: applicants are expected to combine in vitro biochemical and cellular response data with computational modeling approaches and theoretical or applied mathematics. The EPA frames this as research conducted in conjunction with in vivo data, meaning the project should not exist purely in a dish or purely in a computer. Instead, the intended direction is to use in vivo observations as an anchor for model development, calibration, and credibility, while leveraging in vitro systems to generate mechanistic, pathway-level evidence that can be translated into predictive frameworks. In practice, this implies building models that can bridge scales, for example connecting receptor binding or signaling pathway perturbations to downstream effects on patterning, morphogenesis, growth, or differentiation during development.

The scientific scope targets core developmental processes that are fundamental to how organisms form and mature, such as patterning (how body plans and spatial organization arise), morphogenesis (how tissues and structures take shape), selective growth, and cell differentiation. The opportunity highlights the value of understanding the biological pathways that regulate these processes, because developmental toxicity often emerges when critical pathways are perturbed at sensitive windows. By focusing on pathway-based modeling, the EPA is signaling interest in approaches that can generalize across chemicals and contexts, rather than only describing one-off effects. The long-term payoff described in the announcement is a stronger predictive capacity for estimating outcomes or risk associated with specific toxicity processes resulting from developmental exposure to environmental contaminants.

From a program and administrative standpoint, this is a discretionary funding opportunity using a cooperative agreement or grant mechanism under CFDA 66.509 (STAR Research Program). The EPA anticipated making one award, with an estimated total funding amount of $3,200,000 and an award ceiling of $3,200,000, and it explicitly states there is no cost-sharing or matching requirement. The opportunity was posted on November 5, 2008, with an original and current closing date of January 29, 2009, and an archive date of February 28, 2009, meaning it is a historical (archived) solicitation.

Eligibility is broad and includes state governments, local governments (including county and city or township governments), federally recognized tribal governments, public and state-controlled institutions of higher education, private institutions of higher education, and eligible nonprofits with 501(c)(3) status (excluding institutions of higher education in that nonprofit category). The announcement also references an "Others" category with additional clarification in the full text, and it directs applicants to Section III for complete eligibility details. For access issues related to the full announcement, the listed contact is Deborah Segal at (202) 343-9797.

Overall, the opportunity is best understood as an EPA effort to accelerate modern developmental toxicology by funding a coordinated research program that can translate mechanistic in vitro signals into computational models capable of predicting developmental harm from environmental exposures. The focus on integrated data streams, mathematically grounded modeling, and pathway-level understanding reflects a push toward more efficient, scientifically interpretable, and potentially more broadly applicable methods for assessing developmental risks posed by pollutants and toxicants.

Frequently Asked Questions (FAQs)

What agency is offering this funding opportunity?

This opportunity was issued by the U.S. Environmental Protection Agency (EPA) through its Science to Achieve Results (STAR) Research Program.

What is the purpose of this STAR Research Program funding opportunity?

The purpose is to support the creation of computational toxicology research capacity focused on developmental toxicity, with the central goal of funding a research center (or equivalent coordinated effort) to build and validate predictive models of how environmental pollutants and toxicants can disrupt biological pathways involved in normal development.

What type of project is EPA trying to fund?

EPA is aiming to fund a coordinated research center (or equivalent effort) that integrates experimental and computational work to develop and validate in vitro (cell-based or biochemical) and in silico (computational) models that can describe and predict developmental toxicity.

What scientific area does this opportunity focus on?

The focus is developmental toxicity, specifically understanding and predicting how environmental contaminants can interfere with biological pathways that drive normal development.

What does EPA mean by computational toxicology research capacity focused on developmental toxicity?

Based on the solicitation description, it means building a coordinated capability to produce and use computational models (supported by mathematical approaches) together with laboratory-generated mechanistic data to predict developmental outcomes resulting from exposures to environmental pollutants and toxicants.

What kinds of models are expected under this opportunity?

The solicitation emphasizes developing both in vitro and in silico models that move beyond isolated assay results and instead connect measurable molecular and cellular responses to real developmental outcomes.

What is the difference between in vitro and in silico approaches in this solicitation?

In vitro refers to cell-based or biochemical systems that measure molecular or cellular responses. In silico refers to computational models that use those measurements (and other data) to describe and predict developmental toxicity processes.

Is the project expected to use only cell-based assays or only computer modeling?

No. A key feature is integration. The project is framed as research conducted in conjunction with in vivo data, meaning it should not exist purely in a dish (in vitro only) or purely in a computer (in silico only). In vivo observations are intended to serve as an anchor for model development, calibration, and credibility.

How is in vivo data expected to be used in the project?

In vivo observations are described as an anchor for model development, calibration, and credibility. The intent is to align and validate computational and in vitro findings against in vivo observations rather than relying solely on isolated assay outputs.

What does the solicitation mean by moving beyond isolated assay results?

It indicates EPA is looking for approaches that do not stop at reporting single assay outcomes. Instead, the models should connect mechanistic responses (molecular/cellular changes) to meaningful developmental outcomes, improving predictive usefulness for developmental risk.

What kinds of biological processes are within the scientific scope?

The scope targets core developmental processes such as patterning (body plan and spatial organization), morphogenesis (formation of tissues and structures), selective growth, and cell differentiation.

Why is there an emphasis on pathways and pathway-level modeling?

The announcement highlights that developmental toxicity often arises when critical pathways are perturbed during sensitive windows. By focusing on pathway-based modeling, EPA is signaling interest in approaches that can generalize across chemicals and contexts, rather than describing one-off effects.

What is meant by bridging scales in model development?

The solicitation describes models that can connect different biological levels, for example linking receptor binding or signaling pathway perturbations to downstream developmental effects such as patterning, morphogenesis, growth, or differentiation.

What types of data integration are applicants expected to perform?

Applicants are expected to combine in vitro biochemical and cellular response data with computational modeling approaches and theoretical or applied mathematics, while conducting the work in conjunction with in vivo data.

What is the long-term outcome EPA is seeking from this research?
