Indoor Chemistry Projects

Since the average person spends most of their life in enclosed spaces (>90% for the average American), the composition of indoor air is an important factor for exposure, and thereby for human health and well-being. We are interested in the emissions of people indoors and how they vary in response to ozone, temperature, clothing, humidity, age and even emotional state. People are the single common source in any living space and we are focused on characterizing the volatile organic compounds emitted from skin and breath. To this end have taken measurements in chambers, in cinemas and at football games.
