Dr. Aaron Carroll, IU’s director of COVID-19 mitigation testing, talks about his background in medicine, his family life and how he found himself on IU’s coronavirus task force Sept. 1 in a Zoom interview in Franklin Hall. Carroll designed the mitigation testing protocol that students must adhere to, and he said having a robust testing procedure was the only way IU could safely bring students back to campus for the fall 2020 semester.
