Research Interests

I am an evolutionary ecologist and demographer focused on the evolution of life histories and biological interactions in plants. Broad research themes involve the evolution of senescence, the origins and evolutionary maintenance of specificity and specialization, the adaptive significance of dormancy, and the evolutionary dynamics of symbiosis. Other research themes that I tackle include the conservation of rare plants, population forecasting, and the estimation of demographic parameters in organisms with complex life histories. I typically focus my questions on long-lived herbaceous plants, such as orchids and plantains, and have studied both their long-term adaptive dynamics as well as their mycorrhizal ecology, addressing both microevolutionary processes and macroevolutionary patterns. My work has been applied to conservation management, particularly in developing and assessing management plans for rare herbaceous plant species. Field work spans East Asia, North America and Europe.
