This research develops a high-resolution chemical method for analyzing tree rings to reconstruct past climates and ecosystem responses. By measuring atomic-scale chemical variations within cellulose molecules, the study separates environmental signals from biological responses, enabling more detailed understanding of historical climate change, plant physiology, and long-term ecosystem adaptation.

This project applies dendrochronological methods to restored Andean forests in Colombia. It evaluates whether tropical species form annual rings, models their growth over time, and compares results with long-term plot data. The study focuses on Juglans neotropica, Cedrela montana, and Quercus humboldtii, integrating wood anatomy and climatic analysis.
