Derk Arts is a Dutch physician-turned-entrepreneur and the founder and CEO of Castor, a clinical-trial software company he started in 2012 after coding the first version of its Electronic Data Capture platform himself. Trained as a medical doctor and epidemiologist with a PhD, he built Castor to make clinical research more inclusive, patient-centric, and data-driven. The platform now supports thousands of trials across roughly 90 countries and was used by the World Health Organization for its Solidarity Trial. Castor has raised more than $60 million, including a $45 million Series B in 2021, and Arts is a recognized voice on decentralized trials, eConsent, and the responsible use of AI in research.

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.
