ABOUT
Cal-Dendro is a fully equipped tree-ring laboratory within the department of Geography and the Environment at California State University Fullerton. Trevis J. Matheus is the principal researcher of Cal-Dendro.
Becoming a Lab Member:
The world needs more dedicated and motivated students trained in field and laboratory research. As a result I am always looking for new students who are interested in joining the lab or volunteering for field work. If you are an undergraduate or graduate student interested in joining the lab email me: tmatheus(at)fullerton.edu.

RESEARCH
Research at Cal-Dendro primarily focuses on placing our modern climate into context using paleoclimate proxies. We employ a variety of research methods, and sampling procedures to elucidate the hydroclimate of the late Quaternary period. Research topics include eastern Sierra Nevada Mountain snowpack, millennial length examinations of the North American Monsoon, species specific climate response, as well as, developing new species (P. edulis + P. lambertiana) and methodologies for use in dendroclimatology.
