Sexual risk behavior can lead to a host of negative public health outcomes including HIV, sexually transmitted diseases and unintended pregnancies. The Social and Behavioral Sciences faculty focus on understanding health disparities in HIV, STD and unintended pregnancy for vulnerable populations including adolescents (Kershaw, Ickovics), men who have sex with men (Pachankis, Calabrese, Kershaw), racial minorities (Ickovics, Kershaw, Calabrese, Pachankis, Ransome), pregnant women (Kershaw, Ickovics) and women and children from developing countries (Miller). We explore interpersonal (Kershaw), community (Pachankis, Ransome), organizational (Ickovics, Calabrese) and structural/policy (Miller) influences on sexuality and health. We have developed innovative and effective sexual health interventions in health care settings (Ickovics, Calabrese, Kershaw), using biobehavioral approaches (Calabrese), and using social technologies (Pachankis, Kershaw). Social and Behavioral Sciences faculty partner with organizations such as the Center for Interdisciplinary Research on AIDS to conduct research that significantly improves the health and well-being of our communities locally and globally.
