Leszek J. Kaszubowski is a scientist in section of Engineering Geology and Hydrogeology from the Department of Geotechnical Engineering, West Pomeranian University of Technology in Szczecin, Poland. He graduated from Gdäsk University in 1979 achieving the title master of science, specializing in geomorphology and marine geology. The final examination of the doctor's thesis took place in March 1988 at the Maria Curie-Sk¿odowska University in Lublin. Since 1985, he has been an academic teacher and researcher in Department of Geotechnical Engineering in Technical University of Szczecin and since 2009 in West Pomeranian University of Technology in Szczecin. He is working in engineering geology and also in coastal and marine geology. Since 1995, he has been a leader of the Polish Working Group of the International Research Program (IGCP-Project 367- Late Quaternary coastal records of rapid change). In the Commission on Genesis and Lithology of the Quaternary Deposits, Quaternary Research Committee, Polish Academy of Sciences, He is also an active member. In the Polish Society of Friends of Earth Sciences in Szczecin, he is the President of this organization, and also belongs to the Polish Geological Society, Szczecin Division. In the international scientific activity, he is an active member of Coastal Education and Research Foundation, in Coconut Creec, FL, USA. His scientific interests are connected with several research areas, including the geological studies of the coastal zone and seabed of the Baltic Sea, where he uses the high resolution seismic and seismoacoustic techniques, and in applied sciences an engineering-geological and hydrogeological studies for building constructions and environmental engineering. He recently published two scientific chapters (2016, 2018) in the books of Springer International Publishing as a part of the Coastal Research Library series.
