Alfred Wiedensohler studied electrical engineering at the University Duisburg, Germany, and
received his Diploma July 1983. From October 1983 until April 1989, he has employed as
PhD student in the research group Process and Aerosol Measurement Technology at the
University Duisburg and received his PhD in electrical engineering June 1989.
May 1989, he joined the Department of Nuclear Physics at the Lund University, Sweden as
research scientist and later as Assistant Professor.
Since January 1994, he works as senior scientist at the Leibniz Institute for Tropospheric
Research, Leipzig Germany and leads currently the Department “Experimental Aerosol and Cloud Microphysics".
In January 1996, he received the associate professorship and since May 2005, he is
Professor at Institute for Meteorology, Faculty of Physics and Geo-Science, University of
In December 2004, he received for three years the award of a Guest Professor at the College of
Environmental Science and Technology of the Peking University, Beijing, China.
Since October 2018, he is adjunct professor at the Fudan University Shanghai, China.
He is head of the World Calibration Centre for Aerosol Physical (WCCAP) of the WMO
(World Meteorological Organization) in the frame of the Global Atmosphere Watch
Programme (GAW) and the European Center for Aerosol Calibration (ECAC) in the frame of
the European Research Infrastructure ACTRIS.
He was Editor-In-Chief of the journal “Atmospheric Environment” from 2013 to 2018.
He received the award “Highly Cited Researcher” from Thomson Reuters 2014, 2015, 2016 and
In 2014, he received the “Hagen-Smit” award from the Journal Atmospheric Environment.
He is author or co-author of more than 390 peer-reviewed publications in the field of aerosol
and natural science. His research is presently focused on the physical characterization,
process studies, and the climatology of atmospheric aerosols as well as on the development
of new scientific instrumentation.
