Katya Moniz, PhD, has worked for over fifteen years at the intersection of human waste, public health, and the environment. After earning a PhD in Civil & Environmental Engineering from the Massachusetts Institute of Technology (MIT), she shifted from studying microbial ecosystems in the open ocean to those in a somewhat less majestic setting: the human gut (i.e., feces). For four years, she managed multi-institutional research projects as the Research Lead in a microbiome-focused laboratory at MIT, and co-authored numerous papers on the use of wastewater analysis as a tool for public health. During the global COVID-19 pandemic, she took part in a major, multi-institutional collaboration to track SARS-CoV-2 in wastewater from treatment plants across the United States, and managed a pilot program to track the virus at the level of individual buildings on MIT’s campus. Most recently, she led the Global Microbiome Conservancy program at OpenBiome, a non-profit stool bank and microbiome research catalyst, with the aim of increasing representation in human microbiome research and conserving vital microbiome diversity for the future. Katya is an avid outdoorswoman who loves to hike, bike, and paddle both close to home (New England) as well as farther afield – most recently in Patagonia – and is passionate about environmental conservation and scientific capacity-building in under-resourced communities.
