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

From a young age I knew I wanted to help people and I was interested in science and health. I stumbled upon epidemiology while taking a field epidemiology class as a biology major at the University of Nebraska-Lincoln. I now credit that exposure to epidemiology as a defining moment where I saw how I could combine all my interests into a career path. As an MPH Epi student at the UNMC College of Public Health, I learned the fundamental concepts and skills I would need to be a successful epidemiologist in public health practice and learned about the research process. I went on to work as a CDC/CSTE Applied Epidemiology Fellow at the state health department in Denver, Colorado. Through this valuable experience I 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. I returned to Omaha and worked at a local research institution before returning to UNMC in 2017. I recently graduated with my doctorate in epidemiology and am currently pursuing an academic position.
