Research Interests: microbiome, healthy built environments, urban agriculture, food security, carbon footprint
Dr. Gwynne Mhuireach is a research assistant professor in the Institute for Health in the Built Environment at University of Oregon and a third-generation Oregon farmer, operating a regenerative diversified livestock farm on the outskirts of Eugene-Springfield. She has a multi-disciplinary background combining Biology, Architecture, and Landscape Architecture. Mirroring this broad range of experiences, Gwynne’s research interests revolve around the relationships between human and planetary health, focusing specifically on built environment microbiomes and urban food systems. Her past and current projects include explorations of urban grey and green aerobiomes, transfer of soil microbes to human skin during gardening, microbiomes of sustainable building materials (e.g., mass timber, earthen plaster), effects of short versus long food supply chains on food and the gut microbiome, and a multi-institutional collaboration to advance building-integrated agriculture.
