Academic & Research Interest

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, 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.

Since 2010 I have served as Subject Matter Editor for Ecosphere, the open‐access journal published by the Ecological Society of America. I am also Specialty Chief Editor for the Paleoecology section of Frontiers in Ecology and Evolution.
