Description: EPICS Global Air Quality Trekkers (GAQT), led by Dr. Nusrat Jung, is a pioneering initiative dedicated to addressing global air quality challenges by transforming how we monitor and mitigate indoor air pollution. Our mission is to create healthier environments in homes, schools, and workplaces by leveraging cutting-edge technologies and innovative solutions.

Indoor air pollution - caused by toxic chemicals in building materials, furnishings, cleaning products, and outdoor contaminants - poses severe health risks. It is a silent but significant threat linked to respiratory illnesses, asthma, reduced lung function, and chronic pulmonary diseases. Children are especially vulnerable, facing heightened risks that lead to increased absenteeism, reduced academic performance, and long-term health consequences. GAQT is committed to creating transformative change by implementing state-of-the-art air quality sensing networks and next-generation filtration systems, paving the way for cleaner, healthier communities worldwide.

Partners: In collaboration with the Miller School in Lafayette, Indiana, GAQT empowers students, educators, and the broader community to take action against indoor air pollution. Our educational outreach initiatives raise awareness and provide practical, actionable solutions to improve air quality. Supported by the U.S. Environmental Protection Agency’s (EPA) prestigious P3 (People, Prosperity, and Planet) grant, GAQT is designing an innovative smart air purification system specifically tailored for classroom environments. Through the Purdue EPICS service-learning framework, the system integrates real-time air quality monitoring using low-cost sensors to measure critical pollutants such as PM₁₀, PM_2.5, VOCs, CO₂, and O₃. This project aligns with the EPA’s sustainability goals by delivering scalable, affordable solutions for global impact.

Mission: GAQT’s mission, under the leadership of Dr. Jung, is to transform indoor environments by reducing air pollution through advanced sensing technologies and filtration systems. Our work fosters health, productivity, and well-being for individuals and communities alike.

Technologies: GAQT employs a range of advanced tools and technologies to drive innovation in air quality improvement. Fusion360 and AutoCAD enable precise design and modeling of air purification systems, while Arduino and Raspberry Pi power smart hardware for real-time sensing and control. Air quality sensors provide real-time pollutant detection, enabling data-driven solutions for effective mitigation. New filtration technologies advance next-generation purification methods, addressing complex indoor challenges. The Purdue zEDGE Test House offers a real-world environment to validate and refine these innovations, forming the backbone of GAQT’s mission to create healthier spaces.
