The Indoor Aerosol and Exposure Lab is the research group of Brandon E. Boor, an Assistant Professor of Civil Engineering (Architectural Engineering Area) and Environmental & Ecological Engineering (by courtesy) at Purdue University. Our experimental research facilities are located at Herrick Laboratories as part of the interdisciplinary Center for High Performance Buildings (CHPB).
Research Areas & Interests: Indoor air quality (IAQ), HVAC filtration, human exposure assessment, airborne nanoparticles, bioaerosols (fungi, bacteria, pollen, allergens), air quality in occupational workplaces, particle adhesion & resuspension, early-life/infant exposures, combustion aerosols & wood smoke, new particle formation, urban air pollution, low-cost air quality monitoring, health effects of air pollution, and fate & transport of VOCs/SVOCs.
Our research tools, along with those of Herrick/CHPB faculty, include state-of-the-art aerosol instrumentation for studying characteristics of particles from 1 nanometer to 50 micrometers in size, reconfigurable living lab office spaces and air handling units, a full-scale HVAC filter test rig, and a variety of environmental chambers. Our work also takes us outside of the lab, for field campaigns, mobile aerosol studies, and personal exposure monitoring.

May 2017: Undergraduate student awards: Manjie Fu wins Best Poster Abstract Award in the Physical Sciences at the Purdue Undergraduate Research and Poster Symposium for his poster "Crawling‐Induced Resuspension as a Major Source of Particulate Matter in the Infant Breathing Zone" and Rachel Wetterlin wins a Center for the Environment (C4E) Undergraduate Student Summer Research Internship Award for her project "Evaluation of the Indoor and Outdoor Air Quality Implications of Community-Developed Modified Kitchens in Nandi, Kenya."
April 2017: Nandi Clean Kitchen Study & EPICS GAQT undergraduate team featured in Purdue Civil Engineering IMPACT magazine [Spring 2017, pg. 4-5].
January 2017: Research visit and study abroad in Nandi, Kenya with Purdue EPICS GAQT-GEP/I2D Lab team! The aim of our project is to evaluate indoor air pollution and ventilation of modified and traditional Nandi kitchens. The modified kitchens, which were designed and built by groups of Nandi women working with nurse Irene Kalamai of AMPATH Kenya, include chimneys, addiitonal roof-top ventilation pathways, and space to raise chickens below the stove. Following our assessment, we will work with AMPATH to scale-up kitchen ventilation modifications across Nandi.
During our January field campaign, we collected extensive data on particle number & surface area concentrations (10-2,500 nm), CO, CO2, stove/chimney surface temperature (indicator of stove usage), differential pressure across facades, and air velocity at each opening (window, door, roof-vent). Follow the progress of our project on Twitter @AirQualityEPICS.

December 2016: We received an Instructional Innovation Program grant for Purdue AirSense: A Student-Centered Teaching Platform for Air Pollution Sensing and Data Analytics (with Prof. Greg Michalski of EAPS). We will create a state-of-the-art air quality monitoring station on the roof-top of Hampton Hall, measuring particle size distributions down to 10 nm, PM2.5, O3, CO, and NOx, along with a distributed network of low-cost air quality sensors across Purdue's campus. All data will be streamed in real-time to a web-based platform. SURF positions are avaiable for undergraduate students in summer 2017.
