The Patra Lab @ UA in in the Department of Civil, Construction and Environmental Engineering (focus area: Architectural Engineering) is broadly focused on pioneering smart, practical, and accessible solutions to improve indoor air quality, particularly in managing indoor atmospheric particulate matter, including nanoparticles. Our research leverages state-of-the-art real-time aerosol characterization instruments, develops novel particle characterization techniques, and explores innovative filter materials for HVAC systems and air purifiers. Our goal is to create healthier, more resilient built environments capable of autonomously mitigating indoor air pollution.
