My name is Mona Dai and I’m a PhD candidate in Environmental Science & Engineering at Harvard SEAS. I use data science to look at historical patterns of environmental contamination and sociodemographic factors in public water systems in the United States, bringing together my engineering and public health backgrounds. In the past, I’ve also worked at a civil engineering firm and completed a research fellowship at the US EPA. I’m from St. Louis, MO and can (and will!) recommend all the amazing, free things to do in the city. I enjoy playing tennis, rock climbing, paper art, and musicals. I can’t wait to meet all of you!
