About

Dr. N.P. Vaughan is a leading figure in occupational exposure science, with a career dedicated to improving how we measure airborne hazards in the workplace. His core research focuses on the development and validation of personal samplers for inhalable dust—the fraction of particles that can enter the nose and mouth. Vaughan’s most cited work, a 1990 field study with 51 citations, directly addressed a critical gap in industrial hygiene. While laboratory wind tunnels had revealed performance differences between two popular sampler designs, Vaughan’s research took the crucial step of testing them in 23 real-world industrial environments. By using a mobile, articulated, breathing mannequin as a reference, he provided definitive evidence on how these samplers performed under actual working conditions. This landmark study helped standardize exposure assessment methods, ensuring that worker health data is both accurate and comparable across industries. Vaughan’s contributions remain foundational for researchers and practitioners seeking to protect workers from respiratory hazards.
