The technical information I learned about industrial hygiene, toxicology, environmental health and epidemiology is applicable every day for me in my role. Having a varied education including elements of infectious disease, international health and health policy has really helped me bring a diverse background to what I do now.

Real World Application of Public Health Skills and Training

When you enroll at the Yale School of Public Health, you'll hear a lot about the internship and applied practice experience practicum requirements. These immersive experiences are carefully planned, supported and evaluated by our practice and career management staff. Both experiences provide robust opportunities for the real-world application of public health knowledge and skills and support your career goals. Many students report inspiring, life changing experiences from their time around the world and in local settings. Your internship may fulfill the applied practice experience requirement, but if not, there are multiple practicum courses from which you can choose that will provide the hands-on public health practice training required for your MPH degree.

Applied Practice Experience and the Internship

Sample practicum projects

  • Assist in analyzing results from a pilot fruit and vegetable incentive program. Findings were utilized by Wholesome Wave to report back to the community members being served by the programs and will be used to inform a variety of audiences in future reports.
  • Assist in analyzing results from a community survey conducted with residents in New Haven specifically to assess experience with, access to, and hesitancy with obtaining COVID-19 testing. Findings were utilized by the New Haven Health Department to inform policies and programming.
  • In partnership with Dreamkit, developing and implementing a new survey tool to measure youth progress and behavior change through building new skills on an app designed to serve youth experiencing homelessness

Recent internships

Student Research

Contributing to science is important to many of our students and opportunities for research abound at Yale. Many students use their summer internship to do research that culminates in the MPH thesis required by this department. Others work with faculty labs and research teams to access data and formulate their analysis. In addition many students work as research assistants at the Yale School of Public Health, Yale School of Medicine, Yale New Haven Hospital or the VA on faculty research, culminating in peer review publications.
