Kathryn Applegate supports Development and Programs at BioLogos, having been with the organization since 2010. With a Ph.D. in computational cell biology from Scripps Research in San Diego, CA, Kathryn combines scientific expertise with a deep passion for advancing conversations at the intersection of faith and science. After a fulfilling 12-year tenure at BioLogos, Kathryn took a hiatus to focus on family before returning in 2025, more committed than ever to its mission. As the organization’s first Program Director, Kathryn played a pivotal role in organizing transformative events, including two landmark Celebrating Creation conferences with Rev. Tim Keller (2010, 2011) and the Biology by the Sea series of workshops for science teachers. She later led a $5.3 million subgrant program, funding 37 teams across six countries to explore the integration of evolution and Christian faith through scholarly work and accessible resources (2012-2015). Kathryn also launched the Public Engagement program at BioLogos, which included establishing a speakers bureau and organizing national conferences aimed at fostering public dialogue on science and faith. As Resources Editor, she co-edited How I Changed My Mind About Evolution (InterVarsity Press, 2016) alongside Jim Stump and led the creation of Integrate, a curriculum designed to equip parents and educators to navigate the complex relationship between science and faith. Outside of her work at BioLogos, Kathryn serves as Vice Chair of the Board of Directors for the American Scientific Affiliation, an organization that has been connecting Christians in science since 1941. She also leads the meals ministry at church and helps organize the annual book fair at her children’s school. In her free time, Kathryn and her family love traveling and discovering Michigan’s state parks and beaches. She also enjoys curling up with a good book, accompanied by their adorable Cavapoo, Teddy.
