Roxana S. Cremer

Roxana S. Cremer is a PostDoc at the Modeling Department of the Leibniz Institute of Tropospheric Research in Leipzig, Germany. She received her PhD at the Department of Environmental Science of Stockholm University, researching Black Carbon in the Arctic. In her research Dr. Cremer aims to include data from different sources over different scales to find answers on aerosol-cloud interactions, combining observation data from stations and satellites with modeling data. At the moment her research focusses on high-resolution modeling of hurricanes with the German Weather & Climate Model ICON, analysing the microphysical sensitivity and added spectral bin microphysics to the model. She served before as a student board member of the German Association of Aerosol Research (GAeF) and is currently deputy equal opportunity officer at her institute.

From Particles to the Air We Breathe: Dominik Stolzenburg’s Journey into the Hidden Life of Aerosols

Dr. Dominik Stolzenburg is a chemist in atmospheric physics at TU Wien, specializing in aerosol science and air quality. His work focuses on how ultrafine particles form, transform, and affect both climate systems and human health — especially in cities. Through field measurements, modeling, and data analysis, he explores how human and natural emissions interact, helping policymakers shape cleaner ...[Read More]
