EAS Assistant Professor Daniele Visioni

Daniele Visioni

Assistant Professor--Appointment is in the College of Agriculture and Life Sciences (CALS)


Daniele Visioni obtained his Ph.D. in Atmospheric Chemistry and Physics from the University of L’Aquila, in Italy, in 2018. He moved to Cornell in the same year, where he started as a Postdoctoral Associate in the Sibley School of Mechanical and Aerospace Engineering. In 2022, he continued on as a Research Associate in the same department, and also became a Research Scientist I at the National Center for Atmospheric Science (NCAR). He joined EAS in the fall of 2023 as Assistant Professor, and retains a courtesy appointment as Affiliate Scientist at NCAR in the Atmospheric Chemistry, Observation and Modeling (ACOM) lab. He’s the co-chair of the Geoengineering Model Intercomparison Project (GeoMIP), and has been a coauthor of the Scientific Assessment of Ozone Depletion: 2022.

Research Interests

Dr. Visioni’s scientific interest is in the interactions between stratospheric aerosols, chemistry and dynamics in the stratosphere and surface climate, including biosphere interactions: he mostly researches this in the context of explosive volcanic eruptions and of Sunlight Reflection Methods (SRM, geoengineering or Climate Intervention). His research interest in SRM has led him to be involved in multiple research endeavors that connect climate modeling with societal, political and ethical issues around this topic, in particular related to the perceived legitimacy of climate scenarios as used to assess SRM, reliability of climate models and how to improve diversity in the field. He also has strong ties with research groups in developing countries through the DEGREES initiative for which he is a volunteer scientific advisor, with the aim of strengthening the voice of scientists in the Global South in discussions around the topic of Climate Intervention.

He uses a wide range of climate models of different complexities to better understand how well the current generation of Earth System Models used in international assessments are at reproducing the complex interactions between middle atmosphere and surface climate. He is also the co-chair of the Whole Atmosphere Working Group for the Community Earth System Model (CESM), which allows him to explore CESM aerosol-climate interaction in depth, and is involved in projects aiming to improve aerosol microphysics in CESM and other models. His role as the GeoMIP cochair also allows him the opportunity to work with multiple groups around the world interested to understand downstream impacts of climate change and of SRM, such as on fisheries, biodiversity and human health.
