Habilitated doctor of technical sciences, discipline of environmental engineering. Employed as Associate Professor at the University of Warmia and Mazury in Olsztyn (UWM). Scientific research related to the remediation and bioremediation of soils contaminated with trace elements, sorption methods in the removal of pollutants, and the environmental use of bioproducts from (bio)waste. Fractionation of trace elements in environmental samples. Immobilization of trace elements in soils with the use of mineral and organic amendments, including biologically processed waste (compost) and thermally processed waste (biochar, ash). Assessment of the effectiveness of trace element phytostabilization facilitated with various amendments. Technologies of ex-situ and in-situ soil washing with the use of plant and microbiological biosurfactants and new-generation agents recovered from waste (“green” remediation). Valorization of remediated soils.
