Wojciech T. Witkowski
Assistant Professor
AGH University of Science and Technology, Cracow, Poland
Wojciech T. Witkowski is an Assistant Professor at the AGH UST. He graduated from the AGH UST in 2012 with a master’s degree in Geology and Mining and a doctorate in Geodesy and Cartography in 2017. During his doctoral studies, he applied machine learning techniques to model mining-induced groundwater-related land subsidence. This research was made possible by a grant from the National Science Centre of Poland. After receiving his doctorate, he began investigating the application of InSAR to the study of land surface deformation caused by human activities. During the years 2020 and 2021, he worked on the application of COSMO-SkyMed and ICEYE data to the determination of the strain tensor deformation of ground movements and the monitoring of infrastructure deformation in the area of intense ground surface displacements. The National Science Centre of Poland awarded him a grant in 2020 “Novel Algorithm of Sinkhole Precursors Detection”, which is being conducted in collaboration with the Geological Surveys of Israel and Canada. The project assumes that advanced satellite data processing combined with Machine Learning tools will allow for a better understanding of the mechanism of sinkhole formation and the efficient detection of precursors to the deformation process. Wojciech T. Witkowski is a member of the European Geoscience Union and the International Society for Mine Surveying. He has ten years of experience in cooperation with the mining industry in the field of assessing the impact of mining operations on the Earth’s surface.
