PK was born in Agrinio, Greece, in 1981. He received his B.Sc. and M.Sc. in School of Applied Mathematics and Physical Sciences (field of optoelectronics and laser) and his Ph.D. in Atmospheric Physics from the National Technical University of Athens (NTUA), Greece in 2007, 2009 and 2014, respectively. As an undergraduate and graduate research assistant at NTUA he has been working in the field of ground based and space borne active and passive remote sensing techniques. His Ph.D. was focused on a technical part related with the upgrade/optimization of NTUA’s Raman lidar, as well as on aerosol characterization through the synergy of Raman/depolarization lidar and sunphotometric techniques. During his Ph.D., he worked for 3 months (2009), at the Ludwig Maximilians University for the development of a software tool for lidar optimization in near field. He has developed several user friendly software packages for depolarization and Raman lidar signal analysis at NTUA. During the last 5 years, he is responsible for the operation maintenance and data processing of NTUA’s multi-wavelength lidar station (EARLINET member), as well as for ESA’s mobile depolarization/Raman lidar system, currently hosted at NOA.

 

Research Interests:

Backscatter/Raman/depolarization lidar system development (hardware)

Optical design (ray tracing) for lidar optimization

Development of methodologies for the optimization of the overlap effect on lidar technique

Software development for the retrieval of higher level products from raw lidar signals (backscatter, Raman and depolarization techniques)

Application of inversion algorithms for the retrieval of microphysical aerosol properties

Synergetic use of ground-based and space-borne active and passive remote sensing techniques for aerosol characterization

Validation of aerosol-related satellite products using collocated ground-based measurements
