Teaching

For the past 30 years, I have organised and participated in numerous field-schools and summer school programs dedicated to the acquisition and analysis or natural environmental archives. These include the creation of the North American DendroEcological Fieldweek, in 1990 as well as the first three Bolin Centre, Climate Research, Summer Schools. I have hosted many students from around the world keen to learn the fundamentals of tree-ring research, most recently from India and Bhutan.
