FAQs: NSF Biomechanics and Mechanobiology (BMMB) Program

What is the NSF Biomechanics and Mechanobiology (BMMB) program?

The NSF Biomechanics and Mechanobiology (BMMB) program is a discretionary research grant opportunity that supports fundamental, mechanics-based discoveries about living systems. Its focus is on understanding how mechanical phenomena (forces, deformation, transport, flows, material response) interact with biological processes (signaling, remodeling, functional change) in organisms.

What is the main scientific goal of this opportunity?

The core aim is to advance understanding of how mechanical behavior and biological processes influence each other across multiple length and time scales. The program emphasizes mechanics-centered explanations of living systems, rather than isolated biological description or purely applied development.

What does "multiscale" mean in the context of BMMB proposals?

The program is explicitly multiscale, meaning proposals are expected to connect mechanisms and behaviors across levels such as molecular and subcellular processes, single cells, tissues, and whole organs. The framing suggests stronger alignment for projects that link these levels instead of studying only one level in isolation.

What types of mechanical phenomena are relevant to BMMB?

The opportunity highlights topics such as mechanical loading, transport, deformation, and material response, as well as solid and fluid mechanics in organisms. Projects often connect these mechanical drivers to biological signaling, structural remodeling, and functional outcomes.

Is the program focused on solid mechanics, fluid mechanics, or both?

Both. The program description calls out solid and fluid mechanics in organisms and encourages studies of how forces and flows contribute to biological structure and function.

How important is the extracellular matrix (ECM) to the program?

The relationship between mechanics and the extracellular matrix (ECM) is a major emphasis. The program specifically highlights how ECM composition and organization influence mechanics and how mechanics can, in turn, influence ECM remodeling, synthesis, and organization.

What kinds of ECM-related questions fit the BMMB emphasis?

Examples of emphasized questions include how matrix architecture and material properties shape stress and strain fields in tissues; how matrix stiffness, viscoelasticity, and anisotropy affect cell behavior; and how cells reorganize or synthesize matrix in response to their mechanical environment.

Does the program emphasize in vivo mechanics?

Yes. In vivo mechanical forces are highlighted as central drivers of cell and matrix biology, indicating strong interest in studies that connect real physiological forces and flows to biological responses.

What life processes does the program highlight as being driven by mechanics?

The opportunity specifically calls out histomorphogenesis (formation and shaping of tissues), as well as tissue maintenance, regeneration and repair, and aging. This signals interest in how physiological mechanics guide development, sustain homeostasis, drive adaptation after injury, or contribute to degeneration over time.

What research approaches are supported under BMMB?

The program supports theoretical, computational, and experimental investigations. Examples mentioned include constitutive modeling of living materials, analytical mechanics of growth and remodeling, multiscale simulations, fluid-structure interaction, mechanochemical models, mechanical testing of tissues, mechanobiology assays, imaging coupled with deformation mapping, microfluidics, and in vivo loading models.

Are integrated projects (theory + computation + experiments) encouraged?

The description suggests that projects integrating approaches, or using one approach to tightly validate or inform another, can be a good fit. The key is that the central contribution should be fundamental understanding rather than purely applied product development.

Is applied product development the main target of this program?

No. While the program supports a wide range of research methods, it frames competitiveness around fundamental understanding of mechanobiological principles rather than purely applied product development.

What does it mean to treat living tissues as "smart materials that are self designing"?

This theme reflects the idea that biological materials are not passive. Tissues can sense mechanical cues, adapt their structure and properties, and "engineer themselves" through growth, remodeling, and feedback between mechanics and biology. The program encourages research aimed at uncovering principles governing this self-design behavior.

What kinds of "self-design" principles might be relevant?

The opportunity points to ideas such as mechanosensing rules, adaptive remodeling laws, emergent material properties, and coupled dynamics of forces, flows, and biological responses as examples of the types of fundamental principles that may align with the program theme.

What is the CFDA listing associated with this program?

The program is listed within NSF Engineering Grants under CFDA 47.041.

Is there a cost sharing or matching requirement?

No. The opportunity indicates there is no cost sharing or matching requirement.

Who is eligible to apply?

The listing states eligibility is "unrestricted," meaning it is broadly open to applicant types unless additional limitations are specified in the full, current program text.

What are the typical due dates and submission timing for this opportunity?

The archived posting shows a typical annual submission window with due dates by 5 p.m. local time on January 15 and February 15. Because the record indicates the posting has been archived/replaced, applicants should confirm current deadlines in the most current NSF program description.

What is the award size range listed for the program?

The archived record lists an award floor of $5,000 and an award ceiling of $400,000.

The posting is marked archived/replaced. What should applicants do?

The record notes that the particular posting has been archived and replaced by another program description number. Applicants should consult the most current NSF BMMB program description to confirm the current scope, any refinements, current deadlines, and the submission instructions that apply now.

Where can applicants get help with electronic access or submission issues?

For electronic access difficulties, the listing directs applicants to NSF's Grants.gov support at grantsgovsupport@nsf.gov. The listing also indicates applicants can contact NSF regarding linking issues.
