People

The UC Davis Malcolm North Lab is an interdisciplanary group consisting of undergraduate students, graduate students, and postdoctoral researchers. All members share an interest in the ecology of forests in western North America but specialties cover a broad range of topics and use an equally broad suite of methods including common stand exams, genetics, physiology, dendrochronolgy, and GIS. Occasionally, we even dabble in critters that move!

My general research interests are stand dynamics, disturbance regimes, and ecosystem processes of western coniferous forests. In particular I’ve focused on understanding how disturbance alters forest structure producing changes that propagate through the ecosystems’ processes, food webs and species diversity.

My research interests stem from work in New England, Southeast Asian, Pacific Northwest, and Sierra Nevada forests. I have developed a fascination with the functional roles of coarse woody debris across systems with varying disturbance regimes, as well as with the patterns and drivers of tree spatial distributions. I am also interested in forest management strategies, and how cultural perceptions of nature influence the ways in which we interact with it. Currently, I am focusing on forest systems in the western United States, namely the Gifford Pinchot in western Washington and the Yosemite area in California.

I am interested in how tree communities assemble at and above treeline using climate change as a human-timescale proxy for changing environmental conditions.  My work focuses on the “sky island” Basin and Range Mountains of the North American west such as the White Mountains in California where I use plot sampling, experimental common gardens, dendrochronology, and population genetics to study the population dynamics of limber pine and Great Basin bristlecone pine, some of which are the oldest individual living organisms on earth.

 

I am also the Director of GLORIA California, an organization that conducts research in alpine environments to study the long-term community effects of climate change on mountains.

I’m interested in how climate change and biological invasions affect the colonization, persistence, and evolution of populations. My goal is to unite theory with application and data with models to make predictions of population responses to these anthropogenic phenomena at scales relevant to management. My past work included studying how species distributions may shift under climate warming scenarios, and how multiple introduction events may affect the evolutionary ecology of a colonizing population in a novel environment.
