Talia M. Quandelacy is an assistant professor at the Colorado School of Public Health, and is concluding her postdoctoral fellowship in the Analytics/Modeling Unit at the CDC Dengue Branch in San Juan, Puerto Rico. She studies the transmission dynamics of influenza, novel and endemic coronaviruses, dengue, and Zika to inform prevention and control measures and to improve health outcomes both in the US and internationally. Talia received her PhD in Epidemiology (Infectious Disease Epidemiology) from the Johns Hopkins Bloomberg School of Public Health in 2017.
