Juliet Johnston (Emeritus) is an NSF-fellow working on her PhD in environmental engineering. When you flush the toilet, the microbes at a wastewater treatment plant eat the harmful remnants of your waste. She investigates these wastewater microbes and their microbiome in relation to seasonal variation, specifically focusing on nitrification failure during cold temperatures. Additionally, she is the organizer for the nation’s first Queer Science Day to inspire upcoming LGBT scientists. She earned her bachelor’s in environmental engineering with a minor in women’s studies from Clemson University. She is often found lounging in coffee shops, rock climbing, baking, and taking long walks in the bitter cold with her dog.
