My lab's research program focuses on the ecology and evolution of plants in extreme environments. We address questions such as: How does adaptation to extreme environments influence trade-offs in allocation of energy to growth, reproduction, and physiological tolerance? And, how do these trade-offs influence genetic diversity? To address these questions, my lab studies population genetics and reproductive ecology in the desert moss, Syntrichia caninervis, which is highly tolerant of stress and desiccation, and also has the most skewed sex ratios known of any plant species. Because it is essentially an aquatic plant growing in the desert, this moss spends the majority of its life in a desiccated state of suspended animation, awaiting brief interludes of moisture from infrequent rains.
I teach classes in ecology, evolution, science communication, and plant diversity. Here are some of the courses I teach fairly regularly:
BIOL 1010 - General Biology
BIOL 3200 - Professional Writing in the Life Sciences
BIOL 4400 - Plant Systematics
BIOL 4500 - Botanical Medicine
I am always happy to speak with students interested in doing undergraduate or Master's research in my lab. Please take some time to review one or two of my representative publications (listed below) prior to getting in touch with me, so that we can better discuss your research interests and possible projects.

I spent my formative years playing in creeks and ditches in northern California, where I learned to appreciate small, growing things. I earned my undergraduate degree in Biology at UC Santa Cruz, and after a couple of years of varied employment as a gardener, bakery cashier, and bank teller, decided to pursue graduate education. I was wooed into the world of mosses by Brent Mishler at UC Berkeley, who served as my PhD advisor and provided me with the opportunity to study the systematics of a tropical moss family, Calymperaceae. After earning my PhD, I did a postdoctoral fellowship at the National Evolutionary Synthesis Center in Durham, NC, where I learned to appreciate barbeque and California weather. I returned to California in 2008 to join the faculty in the Department of Biological Sciences at Cal State LA, where I am now a Professor.
