Ami Sedani
DO Title: Member at Large
Graduating Year: 2016

Ami Sedani is currently a doctoral candidate in the epidemiology concentration at the University of Oklahoma Health Sciences Center. Her research interests are in chronic disease etiology and subsequently prevention/early detection, as well as the utilization of geographic information system (GIS) in epidemiologic studies. Her research has involved studying risk factors for chronic diseases including lifestyle factors and health disparities. This research spans international and domestic settings, as well as at the state and local government level. She earned her MPH with a concentration in epidemiology from the University of Nebraska Medical Center in 2016, and her BS in Biology from Arizona State University in 2013. During her MPH she was a nutrition educator for AmeriCorps in partnership with Nebraska Extension, interned at the Douglas County Health Department, and participated in the Cancer Epidemiology Education in Special Populations (CEESP) program which allowed her to complete her capstone project in Tanzania. After completion of her MPH, she became a chronic disease epidemiologist at the Nebraska Department of Health and Human Services, where she was the sole epidemiologist on a team of ten for two multimillion-dollar grants from four CDC divisions covering heart disease and stroke, diabetes, school health and nutrition and physical activity.


Kelli Gribben, MPH
DO Title: Member at Large
Graduating Year: MPH in 2011, PhD Anticipated in 2021

Kelli Gribben graduated with her MPH from UNMC in 2014, and is currently pursuing her PhD. Kelli knew she wanted to help people and was interested in science and health from a young age. She learned about epidemiology as an undergraduate biology major at the University of Nebraska-Lincoln. This was a defining moment in which she saw how her interests could become a career. As an MPH Epi student at the UNMC College of Public Health, she learned the fundamental concepts and skills she would need to be a successful epidemiologist in public health practice and learned about the research process. She went on to work as a CDC/CSTE Applied Epidemiology Fellow at the state health department in Denver, Colorado. Through this valuable experience she contributed to several programs under the mentorship of a CDC state-assigned epidemiologist and was exposed to several different topic areas, mainly chronic disease and oral health epidemiology. Kelli returned to Omaha and worked at a local research institution before returning to UNMC in 2017 to pursue her doctoral degree. Throughout her time as a doctoral student she has worked as a graduate assistant on emergency preparedness projects and courses. Her dissertation research investigates genetic and environmental factors related to adult asthma and other respiratory diseases. Kelli plans to pursue a career in public health research and education.
