Paul Szejner

Assistant Professor

Instituto de Geología Universidad Nacional Autonoma de Mexico

Participates in 6 items

As a forest ecologist, I use stable isotopes in tree rings to study the relationships between plant physiology and environmental changes. I am interested in the mechanisms driving carbon and water fluxes on forested regions from seasonal to centennial scales.
