QuantAQ, Inc. grew out of research at MIT and Aerodyne Research, where atmospheric chemists David H. Hagan and Eben S. Cross saw a need for more accessible air-pollution measurements. They founded the company in 2019 to help people measure, understand and address air pollution. 511
Based in Somerville, Massachusetts, QuantAQ develops internet-connected air-quality monitors and a cloud platform for collecting and analysing data. Its team is led by co-founders Hagan, CEO, and Cross, CSO. 23 The company serves researchers, government agencies, industry and communities, with monitors designed to measure pollutants including particulate matter, ultrafine particles, carbon monoxide, nitrogen oxides and ozone. Its platform connects sensor networks for remote, real-time data collection. 1
QuantAQ’s work spans research and practical monitoring. Its published research includes studies on sensor calibration, electrochemical-sensor interference and the accuracy of optical particle sensors. 1 In one customer project, its monitors helped Urban 360 assess air quality in UK classrooms while the project team monitored results remotely from Manchester. 7 Another case study describes continuous dust monitoring in California’s Coachella Valley. 12 Together, these examples show the company’s focus on deploying sensor networks in settings where local measurements can inform research, compliance or community health. 712
