Background
Dr. Lazaros Oreopoulos (a.k.a Lazaros Oraiopoulos) received his B. Sc. in Physics with honors from Aristotle's University of Thessaloniki, Greece in 1989. He received M. Sc. (1992) and Ph. D. (1996) degrees from McGill University, Montreal. After working for a year as a researcher for the Cloud Physics Research Division of the Meteorological Service of Canada (MSC), he was offered a postdoctoral fellowship from the National Science and Engineering and Research Council of Canada, but chose instead to join JCET and NASA in October 1997. Soon thereafter he established an affiliation with the UMBC Department of Physics where he taught a graduate atmospheric radiative transfer course. Dr. Oreopoulos has served as the leader of the JCET Radiation Focus Group for three years and the position of Research Associate Professor within JCET and UMBC-Physics from 2006 to 2008. He is a Physical Research Scientist with NASA-GSFC since December 2008. He conducts research on the modeling and remote sensing of clouds, cloud-aerosol interactions, and many aspects of atmospheric radiative transfer for climatic applications.
