Current Research

I am currently examining the physiological mechanisms behind the high mortality of ancient long leaf pines after fires are reintroduced to long unburned stands. I am also studying the impact of combining prescribed fire with slash pine plantation management practices in Florida to reduce dangerous fuel loads. I am developing a research program on the fire ecology of tropical pine forest ecosystems in southern Florida and the Bahama Archipelago. Generally, I am interested in the relationship between fire and plant ecophysiology, population dynamics and ecosystem properties.
