Asher Rosinger is a human biologist. Upon completion of his doctorate, Dr. Rosinger was chosen as only one of two anthropologists to serve as an Epidemic Intelligence Service Officer at the Centers for Disease Control and Prevention. There, he led field projects and published papers related to national surveillance on dietary water intake and sugar sweetened beverage consumption, obesity, and cholesterol. In addition, Dr. Rosinger deployed three times to Puerto Rico to help build a surveillance system to monitor the range of health outcomes for babies of women who were pregnant and infected with Zika Virus. For this work, he won a CDC & ATSDR Honor Award for Excellence in Emergency Response. At Penn State, Dr. Rosinger directs the Water, Health, and Nutrition Lab, which examines how humans respond to changing nutritional and economic environments through water and dietary intake and the significance of mismatches in these relationships for short- and long-term health, nutrition, and disease. His overall research program is designed to understand the range of human variation in water intake and how this relates to perception, environmental resources, water insecurity, and health, hydration, and disease risk. In particular, he examines these issues in the Bolivian Amazon among indigenous Tsimane’ forager-horticulturalists, in Kenya among Daasanach agro-pastoralists, and in the US using complex survey data from the National Health and Nutrition Examination Surveys (NHANES). He explores the consequences of these strategies, states of health and behaviors, and of different diseases on hydration status using biomarker data. He is also a member of the Household Water Insecurity Experiences Scale (HWISE) consortium, which is working to cross-culturally validate a measure of water insecurity. Prospective students: Dr. Rosinger is accepting applications for a PhD student with the right fit, please email a CV, previous research experience, and detail your research interests including why the Water, Health, and Nutrition lab would be a good fit in your inquiry to arosinger@psu.edu. The BBH PhD program provides 5 years of funding.
