University of Miami College of Engineering on Instagram: "🔬💨 Mechanical engineering master’s student Ragulan Pulanthitan is spending his summer contributing to a biosecurity research project focused on indoor airborne pathogen mitigation. As part of a team in the Department of Chemical, Environmental and Materials Engineering, he helps prepare filters and chemical solutions, monitor experimental systems, collect data, and analyze results. The research examines how glycol, a disinfectant used in some HVAC applications, and varying humidity levels affect the performance of air filtration systems. By measuring how effectively filters capture airborne particles over time, the team is generating data that could help improve strategies for cleaner and safer indoor air. 🌎🦠"
