Heike Wex

Dr. Heike Wex is a prominent atmospheric scientist at the Leibniz Institute for Tropospheric Research in Leipzig, Germany, where she serves as a Researcher in the Atmospheric Microphysics department. With over two decades of continuous research since completing her PhD in 2002, she has established herself as a leading expert in aerosol-cloud interactions and ice nucleation processes. Her work spans multiple international collaborations and major research initiatives including (AC)³, PICNIC, MarParCloud, and PI-ICE projects.

Her research focuses on experimental investigations and theoretical descriptions of aerosol-cloud interactions, with specific expertise in hygroscopic growth at high relative humidities (>99% RH), particle activation to cloud droplets, heterogeneous ice nucleation processes, and the role of atmospheric aerosol particles as nuclei for cloud droplets and ice formation. Her work bridges atmospheric physics, climate science, and environmental chemistry, with significant contributions to understanding how microscopic processes affect cloud formation and climate.

Analysis of her recent publications reveals a strong focus on polar and marine environments, with particular attention to biological contributions to ice nucleation, seasonal variations in Arctic aerosols, and the development of advanced measurement techniques. Her work consistently addresses fundamental questions about how aerosols influence cloud properties and climate systems, with increasing emphasis on climate-relevant processes in polar regions.

Dr. Wex has held significant leadership positions, including serving as Vice President of the International Commission on Clouds and Precipitation (ICCP) from 2021-2024. She is also actively engaged with Scientists for Future in Leipzig, demonstrating her commitment to addressing climate change through scientific expertise and public engagement.

Beyond her research, she has organized numerous scientific workshops and field campaigns, including leadership roles in the LExNo experiment, FROST projects, and the 16th International Conference on Clouds and Precipitation. Her work has established important methodological approaches for studying ice nucleation and has contributed significantly to our understanding of aerosol impacts on cloud formation across diverse environments from the Arctic to the tropics.
