The Graduate School oversees and supports four research centers and an institute on the Main Campus.  These are:

• Center for the Brain Basis of Cognition (CBBC) -- the CBBC promotes basic research and training at the intersection of cognition and neuroscience, with an interest in applying this research to clinical and educational contexts.
  
  
• Center for Infectious Disease (CID) -- established in 2004 to address the following issues:  Promote international health through research and education; stimulate and facilitate communication between Georgetown’s infectious disease researchers and internal and external audiences; provide networking opportunities across infectious disease research laboratories; foster an environment conducive to training graduate students and fellows; solicit and create new funding opportunities for infectious disease research and training, and; strengthen connections between biomedical researchers and policy, ethics and law scholars.
  
  
• Center for Population and Health (CPH) -- established in 1999, the CPH endeavors, among other things, to strengthen and encourage research in the area of population and health at Georgetown; encourage interdisciplinary collaboration among faculty and graduate students across all disciplines on the Main Campus; and to promote a variety of service activities that contribute to the well-being of the DC community.
  
  
• The Georgetown Public Policy Institute (GPPI) -- in addition to offering graduate studies in public policy and policy management and joint degree affiliations at the M.A., Ph.D. and J.D. levels,  the GPPI also conducts academic research on a variety of policy issues relating to children, education, health care, non-profit studies, democratic governance, and the policy-making process.
