Learn About Convergence Research

The U.S. National Science Foundation gives high priority to convergence research, which focuses on addressing complex problems in science, engineering and society.

Today's grand challenges will not be solved by one discipline alone. But the integration of knowledge, methods and expertise from across science and engineering is not simple or automatic. Barriers often slow progress — from outdated educational approaches to rigid organizational structures.

This page provides information on the definition of convergence research and how NSF supports this work.

What is convergence research?


Illustration of glucose molecules on top of a surface
Engineers at Brown University have designed a biochip that can measure glucose concentrations in human saliva. In this illustration, glucose molecules 'dance' on a sensor surface illuminated by light. The technique takes advantage of a convergence of nanotechnology and surface plasmonics, which explores the interaction of electrons and photons.

Convergence research is a means of solving vexing research problems, especially those focusing on societal needs. It has two primary characteristics:

  • It is driven by a specific and compelling problem, whether that problem arises from deep scientific questions or pressing societal needs.

  • It shows deep integration across disciplines. Convergence research intentionally brings together intellectually diverse researchers to develop effective ways of communicating across disciplines. As experts from different disciplines pursue a common research challenge, their knowledge, theories, methods, data and research communities increasingly intermingle.

New frameworks, paradigms or even disciplines can emerge from convergence research, as research communities adopt common frameworks and a new scientific language. In this sense, convergence research is similar to transdisciplinary research, which is seen as the pinnacle of integration across disciplines.

 

Examples of convergence research:

A convergence of the life sciences, physical sciences, computer sciences and engineering is driving research in cyber-physical systems — smart networked systems with embedded sensors, processors and actuators that are designed to sense and interact with the physical world.

In cyber-physical systems, the joint behavior of the "cyber" and "physical" elements of the system is critical: computing, control, sensing and networking can be deeply integrated into every component, and the actions of components and systems must be safe and interoperable.

NSF's Cyber-Physical Systems program awards "Frontier" grants to projects that are developing solutions to challenges that cannot be achieved by small efforts. Examples of these projects include:

A convergence of the life sciences, engineering, statistics and computer science is driving new research into how the mind works.

NSF's Science and Technology Research Centers program, one of the agency's principal means for fostering convergence research, supports centers focusing on the mind and brain, including:

  • The Center for Behavioral Neuroscience: The center has played a major role in developing the field of behavioral neuroscience. Its scientists study the neuroscience of affiliation, aggression, fear, reproduction, and memory and cognition.

  • The Center for Brains, Minds and Machines: The center brings together computer scientists, cognitive scientists and neuroscientists to understand human intelligence and establish an engineering practice based on that understanding.

Synthetic biology aims to construct or redesign biological entities to solve problems. It builds on another convergent field — nanotechnology which came into being through the convergence of chemistry, physics, engineering, life sciences, materials science and many other disciplines.

NSF's Science and Technology Research Centers focusing on synthetic biology include:

  • The Synthetic Biology Research Center: The center has trained engineers to specialize in engineering biology. These engineers will use synthetic biology to build technologies that solve engineering challenges in health care, energy and the environment.

  • The Center for Biorenewable Chemicals: The center is bringing together biologists and chemists to build a sustainable bio-based chemical industry.

Characteristics of successful convergence projects


1. Need for a convergent approach

The research team makes a compelling case for why it is essential to bring together substantially different science and engineering disciplines to address a specific scientific challenge or social problem.

2. Readiness to engage in convergence research

The research team provides evidence of its readiness to perform the proposed research and that the necessary disciplines are represented on the team. This evidence may include previous interdisciplinary projects or joint publications by team members, specialized knowledge residing in the research team that is pertinent to the problem, or co-development of research infrastructure.

3. Integration of knowledge, tools and modes of thinking

The research team makes a compelling case that the knowledge of its contributing disciplines is deeply integrated. It demonstrates strong coupling, high leveraging, or co-development of integrated or complementary tools and techniques. It also demonstrates a novel research approach that deeply integrates its contributing disciplines' knowledge and modes of thinking.

4. Involvement of the next generation of convergence researchers

The research team gives undergraduate students, graduate students and/or postdoctoral fellows opportunities to learn convergence research approaches — and is clear about the tools, techniques and concepts outside their disciplinary specialties they'll learn. Ideally, a project should offer a model learning environment that can be adapted by other convergence research projects.

How NSF supports convergence research


The convergence of disciplines is a process — NSF's convergence research portfolio focuses on addressing the key technical, organizational and logistical challenges that currently hinder convergence research.

NSF's programs support teams with varying degrees of integration between their disciplines, and at varying stages of readiness to adopt a convergence strategy, through grants, workshops and cooperative agreements.

Featured NSF-wide programs:

Offers intense hands-on education and mentoring to teams that focus on translating basic research into solutions with real-world application.

Supports team-based research that crosses disciplinary boundaries and addresses challenges falling outside of NSF's existing programs.

Supports interdisciplinary centers that work on complex research challenges in areas of national priority.
