About Me

My name is Dr. Raymond J. Leibensperger III (he/him) and I investigate natural aerosol emissions, namely sea spray aerosols (SSA). I received my B.Sc. in Marine Science & Applied Physics from the University of Miami in 2020, my M.Sc. in Oceanography from Scripps Institution of Oceanography in 2021, and my Ph.D. in Earth Sciences from Scripps Institution of Oceanography in 2025. My research focuses on the production of sea spray aerosols in laboratory-scale breaking wave proxies using an experimental and observation approach. My specialties include MATLAB, TSI Inc. instruments, and campaign leadership, but I have additional skills in LabView, Aerosol Devices instruments, and Droplet Measurement Technology instruments. 

I am continuing my career at Heidelberg University (Germany), working at the Institute of Environmental Physics, in the AerosoL In Climate ChangE (ALIC2E) research group under the supervision of Prof. Dr. Stephanie Fiedler. Shifting away from aerosol measurements in the laboratory, I will be transitioning into sea spray aerosol modeling, seeking an efficient and applicable model of SSA emissions to be integrated in models across scales.

I am continuously looking for new opportunities, where I would like to better bridge the fields of experiments and observations to improve model parameterizations of natural aerosol emissions. My long-term career goal is to be a principle investigator for a research group investigating natural aerosol treatment in models, and improving parameterizations through field and laboratory experimentation.

Journal of Geophysical Research Atmospheres

  • Using realistic wind‐wave interactions, SOARS generates atmospherically relevant and reproducible sea spray aerosol size distributions

  • Sea spray aerosol concentration scales with wind speed and whitecap fraction, with variability within a factor of 5

  • This study establishes the framework for investigations of how physics, chemistry, and biology influence aerosol‐climate interactions
