A super cool photo of Sean is coming soon!
Troy Ocheltree
I am a plant ecophysiologist interested in understanding the limits of plant survival. I'm interested in why some plants can survive extreme weather events, like drought and heat waves, when others cannot. Understanding these survival mechanisms and quantifying the thresholds of mortality will allow us to better predict the impact of major environmental disturbances.
Sean Gleason
Sean is the smartest, kindest, most creative plant ecophysiologist on the planet. Sean focuses on understanding the ecological implications of the plant water transport system, but has a lot of ideas on all aspects of plant physiology and evolution. The plant ecophysiology group is so lucky to have Sean as part of our team!

Ed Hill
My research interests include quantitative and adaptive silviculture, juvenile tree development, structural heterogeneity of forests, forest microclimates, and tree ecophysiology. My current projects look at how juvenile trees tolerate abiotic stress at different stages of maturity (i.e., how they grow up), how microclimates vary with spatial structure of trees, and how juvenile physiological responses like stomatal conductance reflect fundamental resource changes. I work in many forest types of the southern Rocky Mountains, from high-elevation spruce-fir forests to low-elevation pinyon-juniper woodlands. Prior to forest ecology, I studied military-state relations and African studies in Washington, D.C., and worked in business – never too late to change careers.

Dan Spitzer - PhD Student and Instructor Extraordinaire
I am interested in the different venation patterns of grasses, and am doing comparative anatomy studies on C3 grasses found in a wide range of climates across the United States. Currently, I am examining both lateral and longitudinal vein anatomy and linking these anatomical traits to drought tolerance, growth rate, and frost tolerance in more than two dozen grass species.
