Chang-Yu Wu
Over the past decade, Dr. Chang-Yu Wu has led pioneering research at the intersection of aerosol science, environmental engineering, and human health. His work has advanced understanding of airborne transmission of infectious diseases, particularly respiratory viruses such as SARS-CoV-2 and influenza. Through NIH, CDC-NIOSH, NSF, and DOD-funded projects, Dr. Wu has developed and validated innovative bioaerosol sampling and detection technologies, including water-based condensational growth collectors and point-of-care multiplexed virus detectors. These tools have enabled real-world surveillance of airborne pathogens in healthcare, residential, and community settings, informing risk assessments and infection control strategies. In addition to infectious disease transmission, Dr. Wu has investigated pulmonary toxicity of emerging air pollutants, such as microplastic fibers and complex indoor aerosols, using advanced in vitro exposure systems. His research integrates engineering innovation with public health, as evidenced by highly cited publications, patents on pathogen detection devices, and leadership in multidisciplinary teams. His contributions have shaped best practices for environmental surveillance, occupational exposure monitoring, and mitigation of airborne health hazards, positioning him as a leader in environmental health engineering and translational aerosol science.
