Controlled Experiments

Dr. Klepeis performs controlled studies in chambers and residential settings to study pollutant dispersion and dynamics, and determine emission factors for cigars and cigarettes. He has studied the indoor proximity effect using a multi-point grid of aerosol sensors.

Field Measurements

Many of Dr. Klepeis' research projects have involved field measurements of indoor and outdoor secondhand smoke levels in many types of locations, including homes, automobiles, bars, restaurants, outdoor cafes, smoking lounges, and casinos.

Indoor Air Modeling

An important part of characterizing exposure to air pollutants involves the mathematical modeling of indoor air quality. By theoretically characterizing the dynamics of pollutants, including interactions with surfaces, one can generalize scientific measurements to a wide range of indoor locations. Dr. Klepeis has completed several projects seeking to evaluate and parameterize multi-zone indoor air models, including indoor-outdoor pollutant infiltration models.

Exposure Modeling

Exposure models integrate information on human activity patterns, household factors, and pollutant levels to predict individual or population-level exposure. These models can be used to study how a range of different environmental and behavioral factors influence exposure. Dr. Klepeis has completed several projects where he simulated residential and automobile-based exposure to airborne particles and gases.

Health Promotion

More recently, Dr. Klepeis has initiated research proposals to study how more healthy behavior can be encouraged through education, media outreach, computer simulation ("games"), and real-time feedback on pollutant levels. His new work is pursuing mathematical models that fuse indoor air and human behavior simulation.
