Peccia Lab @ Yale. Research in the Peccia lab at Yale University integrates environmental microbiology and genetics with engineering to address important environmental problems. Principle areas of research include human exposure to microbes and associated human health impacts, wastewater-based epidemiology, and biological control of global methane emission. Along with quantitative engineering-based fundamentals and tools, we have developed extensive molecular and computational biology skill sets and strategic collaborations in public health, epidemiology, and data sciences.
