“Strong soils with poor recognition” – i.e., risks associated with foundation in gyttja

Since 2001, he has been a researcher at the Building Research Institute, currently at the Department of Building Structures, Geotechnics, and Concrete, where he holds the position of professor. He is the head of the Geotechnical Laboratory and deputy head of the Department. He graduated with a degree in engineering geology and construction. In 2008, he obtained a PhD in technical sciences in the field of construction at the ITB, and in 2020, he obtained a postdoctoral degree in civil engineering and transport from the Warsaw University of Technology.
As an employee of ITB, he has prepared over 200 expert opinions and studies on the foundations of various buildings, ground investigation documentation, and geotechnical designs. He conducts geotechnical supervision on construction sites (including as a geotechnical supervision inspector for the expansion of the Warsaw metro). He is the author and co-author of over 90 scientific publications on practical geotechnical issues, particularly related to the performance and interpretation of in situ tests and the determination of geotechnical parameters for design, presented at conferences and symposia in Poland and abroad, and published in technical journals. He is also the co-author of the first guide in Poland on geotechnical design according to EC7 (Geotechnical Design according to Eurocode 7, ITB 2011) and co-author of the monograph Badania Podłoża Budowli (Building Subsoil Investigations), PWN 2020. His main area of scientific interest is the documentation of ground conditions in field and laboratory tests, including the use of seismic methods, and the analysis of the interaction between the structure and the ground for the construction of deep excavations, metro stations and tunnels, and energy facilities, including wind turbines. He also serves as a member of the standardization team of Technical Committee 254 for Geotechnics at PKN and is a delegate at meetings of CEN TC250/SC7 (Eurocode 7 Committee) and CEN/TC 341 (Geotechnical Investigation and Testing) committees, as well as a member of TC 206 (Observation Method) Committee at ISSMGE. He is also a member of the board of the Underground Construction Subcommittee at PKG.
