Katelyn Jetelina

Dr. Katelyn Jetelina is an epidemiologist, data scientist, and one of America's most influential science communicators. She founded Your Local Epidemiologist (YLE) in March 2020 as a few sentences to update her UT Health students about COVID-19 - and somehow that turned into a 365,000-subscriber newsletter reaching people in 133 countries with over 500 million total views. Named a TIME100 Most Influential Person in Health, she translates complex public health science into actionable insights twice a week, covering everything from vaccines and bird flu to gun violence and federal health policy. She holds a PhD in Epidemiology and Biostatistics, consults with the CDC, and serves as an adjunct professor at Yale School of Public Health - all while raising two daughters and having visited 50+ countries.
