Mission
Greater San Diego Biological Solutions is a California nonprofit public benefit research corporation organized for the primary purpose of delivering practical biological solutions to meet critical global health needs.
Program accomplishments
- Serving our mission and primary purpose program in FY2025, Greater San Diego Biological Solutions (GSD Bio) moved forward two key collaborations with research teams at the University of Minnesota, one New England Biolabs (a B Corp), and a major San Diego nonprofit immunology research institute. These relationships involved the transfer of GSD Bio-produced materials and knowledge for immunogenicity testing of dengue and Zika virus vaccine prototypes and for a three-year USDA-funded grant for avian influenza vaccine candidate trials in birds. Along with research, GSD Bio further advanced its commoning biology mission by co-producing and implementing an experiential learning module for the California State University San Marcos (CSUSM) Masters in Biotechnology program, directly benefiting 19 graduate students. Additionally, a GSD Bio project program proposal was integrated into a federal Research Experience for Undergraduates (REU) grant renewal, to create access to project-based and purpose-driven biotechnological education for the next generation of scientists.Expenses $15,254
