CCDD Leadership Update
On January 1, 2026, Yonatan Grad, Professor of Immunology and Infectious Diseases and a part of the CCDD community since 2010, became the Center’s new Director. Trained as an infectious disease physician, Yonatan has worked on preparing for and responding to infectious disease threats—including antimicrobial resistance, sexually transmitted infections, and COVID-19—combining experimental, phylogenomic, and computational approaches.
Jeff Imai-Eaton, Associate Professor of Epidemiology, has assumed the role of associate director. Jeff is a globally respected expert in HIV epidemiology, surveillance, and mathematical modeling and works closely with international public health organizations and ministries of health. Together, Yonatan and Jeff bring a shared commitment to CCDD’s mission of advancing knowledge, mentoring trainees, fostering collaboration, and improving public health.
Our Center
The Center for Communicable Disease Dynamics at Harvard T.H. Chan School of Public Health focuses on improving methods for infectious disease modeling and statistical analysis, quantifying disease and intervention impact, engaging with policymakers to enhance decision-making, and training the next generation of scientists.
How we make an impact
CCDD contributes to academia and the public good through our direct research, advocating for public health policy, supporting faculty-led external initiatives, and training future scientists.
Scientific approaches
At CCDD, we implement various strategies for understanding infectious patterns, predicting public health effects of policy changes, and defining health equity targets.
COVID-19 Press Conferences
Beginning in March 2020, at the start of pandemic, through March 2022, CCDD held 150 Zoom-based press conferences to share scientific insights with the public.
Resources
These resources on infectious disease modeling and planning are created by CCDD and are made open to the public.
