Offered exclusively on the Knoxville campus, the program is housed within the College of Education, Health, and Human Sciences.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The program requires 72 graduate credit hours, including foundation courses, core doctoral coursework, a 9-credit cognate area, electives, and a 24-credit dissertation. Core courses cover advanced biostatistics, epidemiology, dissemination and&nbsp;implementation&nbsp;science, and health behavior theory. Students must pass both a qualifying exam and a comprehensive exam and complete a dissertation defense.&nbsp;<\/p>\n\n\n\n<h2 id=\"why\" class=\"wp-block-heading\">Why study Public Health Sciences?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Public Health Sciences offers the rare opportunity to improve lives at scale. While clinical medicine treats individuals, public health prevents disease and promotes well-being across entire populations, through policy, research, and community action.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The field is interdisciplinary, blending biology, data science, sociology, economics, and ethics. This makes it ideal for people who think across boundaries and care about root causes, such as poverty, environment, and inequality.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Career options are broad: epidemiology, health policy, global health, biostatistics, community health, and more, across government, nonprofits, academia, and the private sector.&nbsp;<\/p>\n\n\n\n<div style=\"height:6rem\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group alignfull utkwds-stack-group has-light-background-color has-background has-global-padding is-layout-constrained wp-container-core-group-is-layout-390953e2 wp-block-group-is-layout-constrained\" style=\"padding-top:var(--wp--preset--spacing--small);padding-right:var(--wp--preset--spacing--small);padding-bottom:var(--wp--preset--spacing--small);padding-left:var(--wp--preset--spacing--small)\">\n<h2 class=\"wp-block-heading\">What can you do with a PhD in Public Health Sciences after graduation?<\/h2>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-002ffff5 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column utkwds-stack has-white-background-color has-background is-layout-flow wp-container-core-column-is-layout-8840effd wp-block-column-is-layout-flow\" style=\"padding-bottom:var(--wp--preset--spacing--small)\">\n<div class=\"wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-1af3027d wp-block-group-is-layout-flex\" style=\"padding-right:var(--wp--preset--spacing--small);padding-bottom:0;padding-left:var(--wp--preset--spacing--small)\">\n<h3 class=\"wp-block-heading\">Government &amp; Public Agencies<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Lead research or policy divisions at agencies like the CDC, NIH, FDA, or state health departments.
