The Training and Outreach Core We propose to create a new “Training and Outreach Core'' which will take advantage of the diverse scientific directions and technologies represented by our team, as well as the unique properties of the larval zebrafish as model organisms for outreach and training. The mission of this core is to increase diversity and support trainees in scientific research. This mission will be carried out by three interlaced programs - Summer Connectomics Internship for Outreach Neuroscience (SCION), BioBus, and Postbac Life Science Fellowship (PLSF). The SCION and PLSF programs integrate students with the U19 research projects and shape them into competent scientific contributors through an active learning framework. The two programs lower the barrier to science research by engaging underrepresented students who do not have research experience and who would otherwise not consider scientific research. SCION recruits motivated high school and college students as contributors to mapping the zebrafish nervous system, combining citizen science with education and career development. PLSF fellows will be primarily recruited from historically black colleges and universities, and will be trained and integrated within a U19 research project with high likelihood of publication. The program places emphasis on work experience and engages postbacs who want to pursue a profession in the life sciences, but lack laboratory experience. The BioBus program interfaces with the local K12 schools to engage middle and high school students with zebrafish neuroscience and to promote STEM education. It serves as a recruitment pipeline for SCION and for the training of postdocs and graduate students as Outreach Fellows. BioBus and SCION both provide frameworks for education and training of graduate students and postdocs in outreach, pedagogy, project management and public speaking. In turn, these pedagogical and mentorship experiences compel the postdocs and graduate students to regularly reevaluate their own research projects, becoming better scientists by teaching.
