	Jeremy Lichstein – Professor I am interested in the ecology of communities and ecosystems, particularly forests. My current research focuses on understanding how forest dynamics and the terrestrial carbon cycle respond to changes in climate, disturbance regimes, and atmospheric CO₂. An underlying theme in my research is studying how biodiversity, especially plant functional diversity, modulates ecosystem responses to environmental change. My research involves field campaigns, analyzing data from large observational networks, and mathematical and computer simulation modeling. I have worked in tropical, temperate, and boreal ecosystems. Opportunities to join our research group are described here. Download CV. E-mail jlichstein@ufl.edu.
	Sagar Budhathoki – PhD Student I am interested in forest ecology and environmental resilience. I have been working on biodiversity enhancement, ecosystem restoration, and invasive species control. In my PhD, I will assess seedling dynamics and forest regeneration under global change and disturbance regimes. By using both field data and large datasets and applying statistical and process-based modeling, I aim to understand how climate factors and disturbances influence forest recruitment.

	Yuanming Lu – PhD Student (co-advised with Bob Holt) Yuanming Lu has concentrated her doctoral work on the invasion of south-Florida vegetation by Melaleuca quinquenervia and the biological control agents deployed against it. Building on an M.S. thesis that documented Melaleuca’s litter-mediated suppression of native seedlings, her Ph.D. research continues to use individual-based simulations to explore how contrasting dispersal rates and host–pathogen interactions shape long-term species coexistence. Yuanming earned a B.S. in Ecology and Evolution from Stony Brook University, NY and an M.S. in Biology from the University of Miami, FL. Broadly, she is a theoretical ecologist interested in invasion biology, and spatial population dynamics—always looking for ways to translate model insights into practical management strategies.

	Thomas Bytnerowicz – Postdoctoral researcher My research encompasses biogeochemistry, plant ecophysiology and the response of terrestrial ecosystems to global change. I am interested in patterns, trajectories, and controls of the nitrogen and carbon cycles and their feedbacks with climate. In my research I use a range of approaches, from methods development, to experiments (greenhouse, growth chamber, field), to theoretical modeling, to terrestrial biosphere modeling, to analyses of forest inventory data. website.

	Dave Frey – Postdoctoral researcher I am an ecosystem ecologist, and I am interested in understanding the controls on forest carbon and nutrient cycling and how these systems respond to global change. My previous research has centered on investigating how soil nutrient availability and acidity influence aboveground and belowground processes in forests, including primary production, soil respiration, and belowground carbon allocation. At UF, I am using forest inventory data to investigate patterns and drivers of changing demography in US forests.. E-mail dfrey@ufl.edu.
