Joan Miyazaki, Member, Maker Faire Committee Chair

Retired Lecturer of Biology, Stony Brook University

Joan Miyazaki received an AB in Biology from New York University, an MS in Botany from Rutgers University and an MS Paleontology from Stony Brook.  As the curriculum coordinator for large enrollment Introductory Biology Laboratories at Stony Brook for 25 years, she wrote the laboratory teaching materials for the undergraduates and trained the graduates students and adjuncts to instruct the labs.  She redesigned the lab curriculum to include skill and inquiry-based experiments and had students design their own experiments rather than follow cookbook experiment instructions. The curriculum included reading professional research literature to develop technical reading skills and to show students what scientists think about and do when they conduct their scientific research.

After working with tens of thousands of freshmen and sophomores, Joan has direct experience with the kinds of skills and knowledge students bring to college. She sees tremendous potential for the ME to enrich STEM education at the pre-college level and broaden community awareness of important issues about our living world. Once we develop awareness, our appreciation can grow, and with experience that appreciation can become a genuine love of the wildlife and the diverse environments on Long Island.

Joan recently retired and has used the time to experience the joys of doing things that she had no time for while working, tai chi, taiko drums, ukulele, mandolin, violin, and fishing. There’s much more she’d like to do including participating in ME with all the amazing people there.
