Four-dimensional physicochemical particle understanding in a blink of an eye: Linking viruses to space observations

Host: Dr. George Agnes



Most airborne particles, or aerosols, are submicron; particles less than 200 nm (nanosized) constitute most aerosols. They are identified as the most critical component in Earth's climate and play an essential role in the changing regional and global change. Yet they are also the cause of millions of premature deaths worldwide every year. Despite the advances in understanding aerosols, we still cannot account for their three-size distribution, shape, topography, surfaces, selected composition, and configuration in real-time and in-situ, which are significant in aerosol-cloud interactions are also critical for their human health impact. We herein share some new AI-laser innovations at McGill to address this challenge, advancing four-dimensional physicochemical processes in the Earth, from nano and microplastics in oceans and viruses in air and water to contaminants like toxic metals such as mercury. We discuss how such quantum leaps in science and technology may advance domains such as medicine, materials, pharmaceutical, and Earth sciences, to satellite/space remote sensing.

Presenting Author’ Biography

Professor Ariya is a James McGill Chair in Atmospheric and interfacial chemistry at McGill University. Her labs research is at the interface of physical and analytical chemistry, focusing on particles, notable on airborne particles or aerosols physicochemical characterization, transformation, and development of novel 4D tracking AI-laser technologies and new mass spectrometry techniques for superior observation. Her labs also develop sustainable technology for air and water particle pollution remediation and ultra-trace detection of gaseous and particulate contaminants. PAA had the pleasure of mentoring over 180 HQP that obtained careers of their choice (e.g., 27 professors, 4 CEOs). She has published >150 peer-reviewed journals, books, and> 400 proceedings. She is grateful to receive several accolades in Canada and internationally. She also served the scientific and policy; for instance, she was the lead author of UN-EP reports on the metal contaminant, led the EU panel on Arctic climate change, and was an expert for the Canadian House of Commons for revision of Canadian Environmental Act.
