    Bio/Research

    Pavlos Kollias is a Professor of Atmospheric Sciences at Stony Brook University and has a joint appointment with the Department of Environmental and Climate Sciences at Brookhaven National Laboratory since 2016. Previously he was a Canada Research Chair at McGill University, Montreal Canada.  Kollias’s research focuses on the understanding of the microphysical and dynamical processes that act at the cloud scale and their accurate representation in numerical models. He is also interested in radar meteorology and technology, and the development and application of novel phased-array and space-borne radars in weather and climate research. Kollias is the author or co-author of over 150 peer-reviewed scientific articles in the areas of millimeter-wavelength radar research, radar technology, signal processing, and cloud and precipitation dynamics and microphysics.

     

    Pavlos Kollias is also the Director of the Center for Multiscale Applied Sensing (CMAS) at Brookhaven National Laboratory. He is a member of the Mission Advisory Group and algorithm development team of the European Space Agency Earth Clouds Aerosols Radiation Experiment (EARTHCARE) Explorer Mission. He has served as a member at the National Science Foundation Engineering Research Center for the Collaborative Adaptive Sensing of the Atmosphere. Kollias also served for three years (2007-2009) as Associate Chief Scientist for the US DOE Atmospheric Radiation Measurements (ARM) program and for six years (2012-2018) as the leader of the Radar Science group of the ARM program. He has served as the Chair of the American Meteorological Society (AMS) Committee on Radar Meteorology and has organized and chaired numerous sessions in international conferences. Kollias has also organized and participated as guest lecturer in several short courses in Europe, North America and Asia on the use of radars in atmospheric research.
