His research focuses on how landscape patterns, climate variability, and land use influence ecological processes, biodiversity, and ecosystem dynamics. By analyzing tree ring widths from living trees, he creates chronologies to identify extreme climate events (droughts, floods, cold summers) and their long-term ecological impacts.
