In the final installment of her ocean science series, Marta returns to Cornell to interview Professor Drew Harvell and one of her past students, Serina Moheed '20. Prof. Harvell recently published a book on marine disease titled Ocean Outbreak, and we discuss her research on marine epidemics and other related topics. Prof. Harvell and Serina worked together in last year's Cornell Ocean Research Apprenticeship for Lynch Scholars (CORALS), and Serina describes her experiences as a student marine researcher.
