Erika D. Tate, PhD
Founder & Chief Executive Officer

Dr. Erika D. Tate founded Bluknowledge to extend the scope and impact of her community service and design-based research experience to support healthy, sustainable, and just communities. In 2009, Dr. Tate earned her PhD in Education in Mathematics, Science, and Technology, from the University of California, Berkeley. Her doctoral research centered on the design and research of technology- and standards-based science instruction that engaged high school students in evidence-based decision-making about community health and environmental justice issues. Outside the Ivory Tower, Dr. Tate has designed a variety of interactive learning experiences that have taught residents about environmental health injustices in classrooms, neighborhood meetings, farmers markets, and after school programs throughout the Bay Area, California and in Savannah, Georgia.  Bluknowledge fuses her social justice orientation, expertise in inquiry-based science and health education, community-centered design and research philosophy, and demonstrated aptitude for fostering creativity and collaboration.
