I am currently an Associate Professor at the Department of Atmospheric Sciences at the University of Illinois at Urbana-Champaign. My research focus is to develop model frameworks to rigorously understand how the microscale properties of aerosols are linked to their macroscale impacts on climate and health. This modeling work lies at the nexus of atmospheric science and computational science, with strong links to laboratory experiments and field observations. I have been heavily involved with the American Association of Aerosol Research, most recently in leading the search for a new Editor in Chief for the association’s journal Aerosol Science & Technology, and in the near future as Program Chair for the 2017 Annual Conference. While I have been living in the US and working in US academia for 12 years, I received my entire education in Germany, including my doctorat degree in Meteorology.
I see myself contributing to the AMS Council in three key areas, with the overall goals to reach out to communities that do not yet consider the AMS as their home and to promote diversity and student achievement: First, I have strong connections to the atmospheric chemistry and aerosol science communities. These communities have been traditionally associated with other societies in science and engineering, not necessarily with the AMS. I look forward to working with the STAC committee on Atmospheric Chemistry and the Publications Committee to increase the involvement of these communities with the AMS, including their participation in the AMS meetings, and increase their representation in AMS journals. I anticipate that my experience as editor for Atmospheric Chemistry and Physics and Aerosol Science and Technology will prove useful in this context. Second, growing up in Germany, I am bringing an international perspective to the council. I have maintained strong connections to the Atmospheric Sciences communities in Europe, and my goal is to leverage these to encourage connections between the European Meteorological Society and the AMS. Third, as a teacher and mentor of the next generation of scientists, I consider promoting student achievement to be a priority. Being part of the AMS Council would allow me to support and foster the AMS scholarship programs, especially targeting underrepresented groups.
