Our Team

CGS is proud of its uniquely qualified interdisciplinary team with unprecedented combination of theory, modeling, data analysis & computer science expertise.

The interdependence of all specialties encompassed by CGS and the CGS team structure, which integrates academic and research institutions, enable deep synergies within the team as well as with the larger Heliophysics community. CGS is led by the largest university affiliated research center in the Nation (JHU/APL) in partnership with the Nation’s premier center for atmospheric science (NCAR), four R1 universities (UNH, VT, Rice, UCLA), and a commercial entity (Syntek). To foster our broadening impacts, the CGS team include collaborators from Howard University, American Museum of Natural History, Maryland Science Center, and NASA Community Coordinated Modeling Center (CCMC). This diverse environment is poised for science breakthroughs; it is ideally suited for NASA workforce development as it enables deep knowledge integration across discipline and generational boundaries and provides robust career opportunities for students, postdoctoral and early career scientists.
