Biography
My research focuses on the development of annually resolved tree-ring proxies to reconstruct climate, discharge and natural disturbances during the Common Era to support risk management related to natural hazards (flood, droughts) and ecosystem-based forest management. I particularly explore how novel applications of flood records from tree rings can improve our understanding of their climatic drivers to improve the regional hydroclimatic predictive trajectories in the context of climate change.
Some of my research branched out into locating and preserving unique natural tree-ring archives of our past hydroclimate. I also study how hydroclimate variability and extremes affect boreal and montane forest ecology and landscapes with a specific interest into riparian and lacustrine forests.
