Summary
I am a tree biologist with a specialty in dendroecology, which is the study of tree rings and wood formation to infer ecological changes. In collaboration with students and colleagues, I have studied tree-dominated landscapes in the Western USA, Mexico, and southern Europe. I am now involved in grant-funded projects aimed at understanding the environmental drivers of intra-annual tree-ring features. Studies performed by DendroLab personnel are focused on examining the connection between wood form and function in conifer species of the western US. We use automated point dendrometers, wood anatomy, and cellular phenology to uncover the exquisitely intricate connections between dendrochronology, wood science, tree physiology, forest ecology, mensuration, and allometry. These new activities also include domestic and international collaborations, the latter with scientists in Canada, Germany, France, Finland, Switzerland, Spain, and Italy.
My teaching responsibilities are closely tied to my research experience and interests. At UNR I have taught several courses, from introductory undergraduate classes to graduate seminars (see list below). I also developed, proposed, and established a few new classes on climate and environmental change.
From 2010 to 2023 I served as Subject Matter Editor for , the open鈥恆ccess journal published by the Ecological Society of America. Starting in 2024 I have become the Associate Editor-in-Chief of the track for that journal.

Accomplishments
My long-term goal is to understand drivers of tree and forest growth in current, past, and future environments. I pursue this goal using instrumental and proxy records (mostly from tree rings), with an emphasis on field observations, numerical calibration, and automated sensors to bridge temporal and spatial scales. My experience and interests are in climate and forest dynamics, particularly in mountain watersheds. This places my work at the intersection between ecology, climatology, biogeography, and hydrology.
My dissertation work on forest growth trends in Arizona had both regional and global relevance. Regionally, it provided evidence for the impact of fire suppression on the ecology of southwestern conifer forests, ultimately contributing to landscape conservation plans. Globally, it showed the importance of placing twentieth-century patterns into a longer historical perspective to disentangle the impact of land use changes (in this case, European settlement) from stand dynamics and other factors. From 1994 to 2000 I conducted research at Scripps Institution of Oceanography on past climate using proxy records from terrestrial tree rings and oceanic sediments (varves). At Scripps I also established a research program in dendroclimatology, and assembled the tree-ring laboratory that I then transferred to UNR. My recent studies deal with quantifying climate and tree growth variability from mountain ecosystems in the Great Basin of North America. Special emphasis is placed on understanding responses to disturbance (wildfire, land use changes) in relation to climate dynamics and to the distribution of woody species at the watershed level.
From 2008 to 2013 I was the statewide lead for the Ecological Change component of an NSF-EPSCoR project entitled “Nevada Infrastructure for Climate Change Science, Education and Outreach”, which was funded for a total of $15 million. As part of the research infrastructure funded by this large multi-investigator project, we established the Nevada Climate-ecohydrological Assessment Network (), which includes valley-to-peak instrumental transects designed to measure changes in atmospheric, hydrologic, and ecologic variables, including the spatial and temporal processes that control, and are recorded by, wood growth of lower and upper treeline species.
