Research scientists work in universities, private companies, government agencies, nonprofit organizations, hospitals, field stations, and more. About half of doctorate-holding scientists and engineers in the U.S. work in business or industry, around 42% work at colleges or universities, and roughly 34% are employed by government, according to National Science Foundation data from 2021. Many scientists move between these sectors over the course of a career, and the day-to-day environment varies dramatically depending on the field.
Universities and Academic Institutions
Universities remain one of the largest employers of research scientists, particularly in the physical sciences and social sciences. Over 53% of physical scientists and nearly 55% of social scientists with doctorates work at colleges or universities. These researchers typically run their own labs, mentor graduate students, teach courses, and compete for grant funding to support their projects.
Within a university, scientists may work in departmental labs, interdisciplinary research centers, core facilities with shared high-cost equipment, or affiliated teaching hospitals. Large research universities often have dozens of specialized centers and institutes, each with faculty and staff who define the center’s expertise. The work environment tends to offer intellectual freedom (you choose your research questions) but comes with the pressure of securing your own funding, publishing papers, and balancing teaching responsibilities.
Private Industry: Biotech, Pharma, and Tech
Business and industry employ the largest share of doctorate-holding scientists overall, and the percentage is even higher for engineers, where over 60% work in the private sector. The types of companies range from massive pharmaceutical corporations to small biotech startups to tech giants running AI and materials science research.
In pharma and biotech, scientists typically work in interdisciplinary teams organized around a disease area or drug target. Oncology, immunology, and neurodegenerative diseases are among the most common focus areas. A scientist at a company like AstraZeneca might lead a small team of eight people searching for compounds that act on cancer targets, then pass their findings along to other teams for further development. The culture varies widely by company size. Small biotech firms and recently acquired research sites often have a more informal, collaborative feel, while larger organizations may have more structured hierarchies.
Contract research organizations (CROs) are another major employer in industry. These specialized companies run clinical trials, manage data, handle regulatory paperwork, and perform lab testing on behalf of pharmaceutical and biotech clients. CROs range from full-service firms covering every stage of drug development to niche companies that specialize in a particular disease, research method, or geographic region. Scientists at CROs tend to work on a wider variety of projects than those at a single pharma company, since they serve multiple clients.
Government Agencies and National Labs
Government employs a substantial share of research scientists, particularly in the physical sciences, where about 31% of doctorate holders work for government entities. In the U.S., major employers include the National Institutes of Health (NIH), the Department of Energy’s network of national laboratories, NASA, the Centers for Disease Control, the Environmental Protection Agency, and the U.S. Forest Service, among many others.
The NIH alone houses thousands of scientists across institutes like the National Institute on Drug Abuse and the National Institute of Diabetes and Digestive and Kidney Diseases, all focused on advancing medical research and public health. National labs such as Los Alamos, Brookhaven, and Lawrence Berkeley employ physicists, chemists, materials scientists, and engineers working on everything from nuclear energy to particle physics to climate modeling. Government scientists generally have more job stability than those chasing academic grants, though the research agenda may be more directed by agency priorities.
Field Stations and Remote Sites
Not all research happens in a building. Environmental scientists, ecologists, geologists, and marine biologists frequently work at field stations, on research vessels, or at remote monitoring sites. The U.S. Forest Service, for example, operates a network of Urban Field Stations where scientists study urban and suburban ecology, collecting long-term data across jurisdictions. These stations function as both physical research locations and hubs for interdisciplinary collaboration.
Similar networks exist for ocean research (aboard ships or at coastal marine labs), polar science (at Antarctic and Arctic research stations), and wildlife conservation (in national parks and reserves worldwide). Field scientists may split their time between months of data collection in rugged outdoor settings and months of analysis back at a university or agency office.
Nonprofit Organizations and Foundations
Nonprofits are an often-overlooked employer of research scientists. This category includes think tanks, scientific societies, private foundations, museums, zoos, aquariums, and advocacy organizations. The Howard Hughes Medical Institute, the Fred Hutchinson Cancer Research Center, and SRI International all employ scientists directly. The RAND Corporation hires researchers to study policy, military, and technology questions.
Foundations like the Bill and Melinda Gates Foundation and the Alfred P. Sloan Foundation hire scientists not just to do research but to organize it. In these roles, a scientist might set research priorities, coordinate teams of academic and industry researchers, and direct funding toward specific problems. This approach lets foundations tackle complex challenges in a more focused way than individual academic labs typically can, since university researchers must also teach, write grants, and manage students.
Scientific societies like the American Chemical Society and the American Association for the Advancement of Science also employ scientists in roles that blend research expertise with education, publishing, and public outreach.
Hospitals and Clinical Research Sites
Research scientists in medicine often work in hospitals or dedicated clinical research centers, and their environment depends on whether they do clinical or laboratory research. Clinical researchers test treatments directly on human participants, recruiting patients, monitoring health outcomes through wearable devices and regular checkups, and managing trials that may be spread across multiple hospital sites or run remotely in decentralized models.
Laboratory researchers in a medical setting work in a very different way. They study biological, chemical, or physical processes in controlled environments, using cell cultures, animal models, or computational simulations rather than human subjects. Many medical research scientists straddle both worlds, spending part of their time seeing patients and part in the lab, a role often called “physician-scientist” or “clinician-researcher.”
Where Research Hubs Are Concentrated
Research scientist jobs are not evenly distributed. The 2024 Global Innovation Hubs Index ranks San Francisco-San Jose, New York, Beijing, Boston, and London as the top five metropolitan areas for innovation and research activity. New York leads the world in research innovation specifically, with deep concentrations of research talent and knowledge creation. In the U.S., the Baltimore-Washington corridor (home to NIH, Johns Hopkins, and dozens of federal agencies), the Research Triangle in North Carolina, San Diego, and Seattle also rank among the top 20 globally.
That said, every state has universities, hospitals, and companies that employ research scientists. Remote work and decentralized clinical trials have also expanded options in recent years, particularly for computational researchers, data scientists, and those in trial management roles who can work from anywhere with internet access.
