Soju Chang is the chief of the Initiatives & Consortium-Wide Activities Section of the Clinical and Translational Science Awards (CTSA) Program Branch within NCATS’ Division of Clinical Innovation. Chang joined NCATS as a medical officer and program director in November 2018. He manages a portfolio of CTSA Program grants, leads the CTSA Program Collaborative Innovation Awards (CCIA), and represents NCATS on NIH’s Maternal Mortality Task Force for the Implementing a Maternal health and PRegnancy Outcomes Vision for Everyone (IMPROVE) Initiative and the Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) public-private partnership’s ACTIV-1 platform trial leadership group. In addition, he contributed to the Trial Innovation Network–supported clinical trials in the Pain Management Effectiveness Research Network as part of the Helping to End Addiction Long-term® Initiative, or NIH HEAL Initiative®.

Prior to joining NCATS, Chang served as a medical officer/medical monitor at the National Institute of Allergy and Infectious Diseases for 10 years. He began his career in the U.S. Public Health Service as an Epidemic Intelligence Service officer at the Centers for Disease Control and Prevention in 2001. From there, he transferred to the Center for Biologics Evaluation and Research at the U.S. Food and Drug Administration as a medical epidemiologist in 2003.
