Vasileios Barlakas (VB) was born in 1986 in Thessaloniki, Greece. He received his BSc in Physics and his MSc in Environmental Physics from the Aristotle University of Thessaloniki. In 2012, VB moved to Germany (Leipzig) to do his PhD in light scattering theory at the Leibniz-Institute for Tropospheric Research (TROPOS). His dissertation involved the development of a three-dimensional (3D) radiative transfer model, including polarization, and its application to scientific issues with an emphasis on optical heterogeneities. After his PhD, VB worked as a researcher at TROPOS, wherein he focused on evaluating the performance of atmospheric models to simulate clouds by utilising observations from different satellite sensors. As of 1 February 2019, his EUMETSAT (European Organisation for the Exploitation of Meteorological) fellowship, hosted by the Chalmers University of Technology in Sweden (Gothenburg), is ongoing. His main goal concerns the improvement of microwave (MW) radiative transfer simulations in all-sky conditions, either as part of stand-alone retrievals or data assimilation. A special emphasis is given to the upcoming satellite mission of ICI (Ice Cloud Imager) that will operate at microwave/sub-millimetre frequencies and hence, offering some distinct advantages for sounding of cloud ice properties.

RESEARCH INTERESTS:

Three dimensional radiative transfer including polarization; improved utilization of satellite data for retrievals, numerical weather prediction models, and forecast model validation; aerosol and hydrometeor orientation.
