  • Acquire and analyze observational data, interviews, surveys, and biological samples to find the causes of health problems.
  • Manage public health programs by monitoring their progress, analyzing data, and suggesting improvements.
  • Communicate research findings to health practitioners, policymakers, and the community to improve public health outcomes.
