Dr. Timothy Kittel is a research ecologist and climate scientist.  After receiving his PhD in Ecology from the University of California, Davis, he was a Postdoctoral Fellow at the Cooperative Institute for Research in the Atmosphere, Colorado State University, Ft. Collins.  Dr. Kittel has since held research positions at the Natural Resource Ecology Laboratory (Colorado State University), the University Corporation for Atmospheric Research (UCAR), and the National Center for Atmospheric Research (NCAR), before joining INSTAAR in 2004. 

Dr. Kittel has worked for more than 30 years in the field of global change science, with contributions to our understanding of climate-biosphere interactions and historical climatic change and to the modeling of regional ecosystem and climate dynamics.  Dr. Kittel's work on climate change impacts has been included in IPCC and US National Assessments.  His current research is on approaches for handling climate change uncertainty in biodiversity conservation and on the nature of recent climate change in high mountain regions.  Dr. Kittel has published more than 85 peer-reviewed articles and book chapters in ecology and climate dynamics, along with 39 climatic and ecological public-access datasets. 

Dr. Kittel's teaching emphasizes field instruction in ecology and conservation biology.  He has taught field courses for the University of Colorado-Boulder, Columbia University of New York, University of Nevada-Las Vegas, and Semester-at-Sea (University of Pittsburgh/University of Virginia-Charlottesville).  He currently teaches Winter Field Ecology and Field Methods in Vegetation Ecology in the Colorado Rocky Mountains and study abroad courses on conservation in practice in Brazil.
