Research interest

I'm mostly interested in figuring out how species composition is determined in tropical tree ecosystems. Why are some species dominant while others are rare, is it because of more neutral processes as proposed by Hubbell's Neutral Theory of Biodiversity and Biogeography (2001) or are there other (deterministic) mechanisms at work? The combination between ecological and evolutionary mechanisms and time-scales interest me in answering this and many other questions regarding species composition.

Current research topics

How important is migration in maintaining diversity in tropical tree ecosystems? Can we determine the relative importance of stochastic vs deterministic process when it comes to shaping patterns such as the well known species rank abundance curves or species area relationships?
