Dr. Rezanezhad's research broadly focuses on soil-water-atmosphere interactions and the effects of climate change and management practices on carbon and nutrient biogeochemistry in natural and disturbed ecosystems. He has extensive field experience in terrestrial and wetland ecosystems, specifically with soil and water quality, and nutrient and greenhouse gas flux monitoring. His current research targets cold regions Critical Zone science with a particular focus on hydro(bio)geochemical soil processes in cold-temperate to subarctic and permafrost regions.
