Research on indoor environments has been conducted for decades, but new molecular tools and collaborative efforts are generating a deeper understanding of the complex interactions among human occupants, built environments, and associated microbial communities. Let us introduce ourselves – we’re: Diane Gold, Professor of Medicine at Harvard Medical School, Professor in the Department of Environmental Health at the Harvard T. H. Chan School of Public Health, and Associate Physician at Brigham and Women’s Hospital Vivian Loftness, University Professor, Paul Mellon Professor, and Andrew Mellon Professor in the School of Architecture at Carnegie Mellon University; Jordan Peccia, Thomas E. Golden, Jr. Professor of Chemical & Environmental Engineering at Yale University Today we’ll be discussing the current state of this knowledge, examples of knowledge gaps and challenges, and areas where a research agenda is needed so that indoor interactions can be better predicated and managed.
