Head of College Office

Head of College Jordan Peccia is the Thomas E. Golden Professor of Environmental Engineering and Chair of Yale’s Chemical and Environmental Engineering Department. Profesor Peccia joined Yale in 2005 and leads a research laboratory that integrates the problem-solving aspects of environmental engineering with microbial genetics and public health. His lab has patented genetic-based tests to determine if buildings have hidden mold problems, developed and tested new technologies for inactivating airborne pathogens, and studies how microbes in forests can contribute to the emission of methane, a potent greenhouse gas. During the COVID-19 pandemic, Professor Peccia’s lab pioneered the use of wastewater surveillance to track infectious disease in a community.

In research, Professor Peccia wants to impact big problems facing the world, and he seeks to do the same in teaching and service. He served as the faculty adviser for Yale’s Engineers Without Borders group from 2013 to 2023, where teams composed of Yale students and a professional mentor built water infrastructure for villages in Cameroon and Tanzania. As an outgrowth of his research, his lab continues to provide up-to-date infectious disease surveillance information for southern Connecticut. He is a member of the Yale-New Haven Teachers Institute, leading seminars on climate change and environmental justice for junior high and high school teachers who teach in underserved schools.

Professor Peccia grew up in Cut Bank, Montana, a small town whose unofficial motto is “the coldest spot in the nation.”

Associate Head of College Melissa Castleman is a writer. She recently finished a novel about two sister surgeons living in a climate-changed future. Before focusing on fiction, she was a food and travel writer for national magazines. She received a BA in English from Harvard University and an MFA in Fiction from Columbia University. 

Head Jordan and Melissa’s 15-year-old son, Julian, is a high school freshman and loves anything related to flying. He is a runner, golfer, skier, painter, and an avid baker. A maker of drone films, Julian likes to explore rivers, oceans, and forests for new footage.

Dash, a black Lab, is thrilled to be at Yale and to have skipped middle school and high school to get there. When you see him in the courtyard or the Head of College’s house, you’ll make a loyal friend if you take a few moments to say hello or play with him.
