Yannis Drossinos is a Senior Research Scientist at the European Commission’s Joint Research Centre. His research activities explore aspects of theoretical aerosol physics, including particle formation and transport in laminar and turbulent flows, thermophoretic transport, homogeneous and heterogeneous nucleation, and statics (morphology) and dynamics (agglomeration and fragmentation) of fractal-like agglomerates. He has also studied the transmission dynamics of respiratory viruses, and more recently he has developed epidemiological models for the transmission dynamics of SARS-CoV-2. He studied chemistry at Yale University (BSc), mathematics at Columbia University (MSc), and completed his doctoral degree in chemical physics at Harvard University. He was a Visiting Professor at the School of Mechanical and Systems Engineering, Newcastle University (2004-2010), an Honorary Research Associate of the Department of Physics and Astronomy, University College London (2014-2019), and a Visiting Researcher at the Department of Mechanical Engineering, University of Minnesota, Minneapolis (fall 2018). He chaired the Fundamentals Working Group of the European Aerosol Assembly (2012 – 2017) and he has been a member of the scientific committee of numerous European Aerosol Conferences. He is a founding member of HAAR. He currently serves as an Editor for Aerosol Science and Technology.
