Funds from this grant support MoBE 2017, a two-day Microbiology of the Built Environment Research and Applications Symposium to be held October 11–12, 2017 at the U.S. National Academies in Washington, D.C. The purpose of the symposium is to engage and inform potential funders and community stakeholders by highlighting research findings, identifying intersections with stakeholder missions, and showcasing a National Academies consensus study, Microbiomes of the Built Environment: From Research to Application, which documents the state of knowledge on the microbiome/built environment interface, identifies knowledge gaps, and sets out a list of prioritized areas for future research. Each day of the symposium will include one keynote speaker and four themed sessions. Topics to be discussed include the nexus of microbial exposure and building design, public health and indoor microbial communities, manipulating microbiome composition through architectural choices and material selection, and potential applications of indoor microbial research. A total of 160 guests are expected, including researchers, journalists, industry representatives, and policymakers from state, federal, and international government bodies. MoBE 2017 promises to be an important capstone event for the Foundation’s MoBE program as we near the end of planned grantmaking in 2017. If successful, it will engage and inform potential funders and community stakeholders from government agencies, philanthropic organizations, and companies, while celebrating the scientific achievements of the program.
