Epidemiology Major

The Epidemiology Major is dedicated to studying the distribution patterns and influencing factors of diseases and health states within populations, providing the scientific basis for disease prevention and health promotion. Its curriculum integrates biostatistics, research design, and data analysis, cultivating students' core competencies in diverse fields such as disease surveillance, outbreak investigation, health policy evaluation, and clinical research. Exploring the Epidemiology Major is a key pathway to becoming a vital professional who bridges medical evidence, data analysis, and public health action.

1. Introduction to the Epidemiology Major

Epidemiology is a core methodological discipline within public health and an applied science. It studies the distribution patterns of diseases, health conditions, and their influencing factors within specific populations, applying these findings to prevent and control diseases while promote health. Its core lies in employing scientific research designs, systematic data collection, and rigorous statistical analysis to uncover the causes of health issues, predict their trends, and provide evidence-based support for public health decision-making. This major cultivates interdisciplinary professionals with a solid foundation in statistics, a keen public health perspective, and strong analytical capabilities, serving as a bridge connecting medicine, data, and public policy.
