  • I have spent much of the past three decades focused on tropical dendrochronology on mainland Southeast Asia with a focus on the long-term variability of regional hydroclimate.  This work has led to the development of a robust collection of tree-ring based growth indices (e.g., ring width, earlywood and latewood width as discrete variables, earlywood minimum density derived from Blue Intensity, and stable isotopes of Oxygen) from Thailand, Vietnam, Laos, Cambodia, Myanmar and Lao PDR. From these data we have learned much about the past behavior of the Asian Monsoon and decadal-scale climate features such as the Interdecadal Pacific Oscillation or IPO (Buckley et al, 2019 in Climate Dynamics). Along with the research into the regional climate, I have been working with plant ecophysiologists to understand how trees respond to climate in a mechanistic way.  
  • Prior to the work in Southeast Asia I spent years working along the northern treeline in Alaska and Canada, working largely on reconstructing temperature with long-time colleagues Rosanne D'Arrigo and the late Gordon Jacoby. To that end we recently got a project funded to update and reanalyze our collections along the northern Labrador treeline in eastern Canada. That work is revealing recent changes to the mean state of climate over the region and how they are impacting the boreal forests.
  • I also spent years in the southern hemisphere, studying the long-lived souther conifer Huon pine, of the family Podocarpaceae, as well as New Zealand's ancient Kauri, of the family Auracauriaceae.  In all of these studies I like to look at tree rings as incorporating multiple aspects of the environment, and taking into account the physiology and ecological aspects of how trees grow.  I am currently focused on understanding in far greater detail the physiological and ecological aspects of tree growth in response to climate.  There is much exciting work yet to be done, and along with my colleagues from around the world, I plan to be addressing these important questions for a long time to come.
