My research program is directed towards studying feedbacks between soil processes and biogeochemical cycling of elements in terrestrial environments affected by natural and anthropogenic-induced changes. My process-based approach focus on the soil system, which by nature, integrates processes at different scales and from different disciplines. My current research projects, centered on pedology, go from soil biogeochemical processes, soil-plant feedback interactions and biogeochemical cycling of elements under various pedological, biotic, climatic and geological conditions to more diverse interests by collaborating with research teams in applied geochemistry, functional ecology, plant physiology and soil microbial processes. My primary research objective is to apply the knowledge of soil science for the purpose of suggesting sustainable management of ecosystems: increasing the resistance and resilience of soil-plant systems while decreasing human-induced pressures on the environment.
