The Transition Program in Clinical Research (TPCR), housed in laboratories in Rockville and at the NIAID International Center of Excellence in Research (ICER) Cambodia, integrates innovative ideas like vector-targeted immunological strategies and cutting-edge technologies like pathogen metagenomic sequencing into traditional epidemiological studies in Southeast Asia. Together, the team aims to apply and translate our findings to inform public health and disease prevention measures like vector control as well as vaccine development and implementation.
