Katrianne Lehtipalo is a Professor at the University of Helsinki, affiliated with the Institute for Atmospheric and Earth System Research (INAR) within the Faculty of Science. Her research focuses on atmospheric aerosol formation, new particle formation mechanisms, and their implications for climate and air quality. She holds a docent (Adjunct Professor) position at the Department of Physics and has contributed to major projects like the CERN CLOUD experiment and the EU-funded RI-URBANS initiative. Her work spans experimental, field, and computational studies, addressing topics such as aerosol chemistry, pollution dynamics, and the impacts of atmospheric particles on climate. Key research areas include the formation and growth of atmospheric nanoparticles, the role of organic vapors and ions in nucleation, and the effects of anthropogenic and biogenic emissions. Lehtipalo has led projects on aerosol measurement techniques and contributed to understanding particle behavior in diverse environments, from boreal forests to urban centers. She has been recognized with awards like the Väisälä Award (2022) and World Cultural Council Special Recognition (2023), highlighting her scientific contributions. Her professional activities include peer review for journals like Nature Geoscience and Environmental Science & Technology Letters , organizing conferences, and supervising doctoral research. Collaborations span global institutions, and her work has advanced the integration of field observations, laboratory experiments, and modeling in atmospheric science.
