DEVELOPMENT CORE PROJECT SUMMARY The Development Core of the Oregon State University Center for Advancing Science, Practice, Programming and Policy in Research Translation for Children’s Environmental Center (ASP3IRE Center) provides scientific rigor, time-sensitive funding for innovative research and training for scientists in children’s environmental health research. The Development Core will strategically develop data science methods for precision CEHRT and attract, retain and support a cadre of highly qualified interdisciplinary CEHRT scientists. Our Development Core will leverage CEH concerns brought forth through citizen engagement and examine how, why and where environmental hazards or concerns exist, using data science methods. In addition, the Development core will fund, train and mentor teams of innovative scientists focused on research projects in CEH. Specifically, this includes funding 15 rapid cycle catalyst projects with 1-year timelines. The Development Core is well-situated within the ASP3IRE Center to provide strategic support to scientist from a variety of disciplines, who are interested in furthering their knowledge and training in CEH research. Our core will work closely with our trusted conduits (extension, early childhood educators and CCOs), as well as all cores within the ASP3IRE Center.
