What is a Master of Science (MS) Degree?

A Master of Science (MS) degree will prepare you for a career in research or analysis, or for an opportunity to apply to a PhD program.

With an MS from the University of Minnesota’s School of Public Health (SPH), you will be able to:

  • Draw inferences from quantitative data.
  • Write and evaluate scientific literature.
  • Help direct the future of healthcare.

How is an MS different from an MPH?

The Master of Science and Master of Public Health degrees prepare students to help improve the health of the general public. However, they come at this goal from different perspectives.

An MS is designed for students who want a career in research or analysis. The MS degree can also serve as a stepping stone for students wanting to continue their education with a PhD. With an MS, students can focus on a specialized field of study. Through research and analysis, graduates can help inform and develop the best health care practices that MPH graduates help implement and communicate.

An MPH program trains students to become public health practitioners who work in government, at non-profits, or in industry to work with communities, implement and evaluate public health programs, and/or help raise public awareness of best health care practices.

Benefits of earning an MS

Graduates with an MS degree can do research and work that has grand-scale implications. Advances in their field of study can improve the health of millions, if not billions, of people worldwide.

The job outlook is also bright. According to the Bureau of Labor Statistics, the healthcare industry is expected to add more jobs than any other field in the coming decade. Health care jobs in general are expected to increase by 14 percent and management roles by 28 percent between 2021 and 2031.

Graduates with an MS may also find lucrative salaries. Here are the average salaries in the U.S. for jobs that often require a Master of Science degree, as reported by ziprecruiter.com:

Job Title Average Salary in U.S.
Academic Physician $82,121
Biomedical Researcher $74,910
Biostatistician $118,078
Environmental Chemist $57,466
Epidemiologist $89,398
Occupational Hygienist $72,580

Why choose an MS program at the School of Public Health?

An MS degree from our top-ranked school of public health provides a comprehensive curriculum that prepares students to take on the challenges of a rapidly changing world.

Research done at SPH has led to many innovations with far-reaching effects. A few examples are:

  • First model to predict probability of complications from radiation therapy
  • First report to show high rates of concussions associated with youth football players
  • First city-wide ban of cigarette vending machines in the U.S.
  • FDA-proposed restrictions of tanning bed use by people 18 years of age and younger
  • Changes in the care and treatment of HIV-positive people worldwide based on the SPH global START trial
  • Development of the Minnesota Model used nationwide to track food-borne illness outbreaks
  • Development of the Minnesota Code to read electrocardiograms in a universally applicable and understandable way

Which MS program is right for me?

SPH offers the following MS programs:

  • Biostatistics
  • Clinical Research
  • Environmental Health
  • Health Services Research, Policy & Administration
  • Occupational Hygiene

Each program requires a thesis and usually takes two to three years to complete.


Data without analysis are random facts. Biostatisticians develop analysis tools and methods to drill through the data and extract meaning that can be used to solve health-related problems.

This is a rapidly developing field with career options in academic, governmental, non-governmental, and private industries. Prior to graduation, most MS students are able to secure a job with a starting salary between $65,000 and $80,000.

Clinical Research

The more we know, the more we realize how much we don’t know. Clinical researchers play a critical role in increasing our understanding of diseases and their outcomes.

Students learn how to interact with patients to better understand disease; develop therapeutic interventions; conduct clinical trials; conduct epidemiologic and behavioral studies; and write grants.
