This week Radio Joe was live from beautiful Boulder Colorado and Colorado University at the 5th SLOAN Microbiology of the Built Environment Conference. The conference is a gathering of the leading researchers in the world that study the microbiome of the built environment. A diverse group of scientists from around the world have been meeting for the past five years to present their findings and collaborate on how the microbiome of the indoor environment can be defined, investigated, maintained and when necessary remediated. Joining us live from the conference were Carl Grimes; Ulla Harvenin Shaughnessy, PhD; Sarah Kwan, PhM, EIT; and PhD Candidate at Cal Berkeley, Iman Sylvain.
