I am interested in determining suites of plant functional traits (ecological, morphological, and physiological) and how these suites allow species to grow in different environments.

My interest is broadly on soil carbon sequestration in tropical ecosystems, focusing on how traits of woody species influence rates of decomposition. Beginning next summer, I plan to measure traits of woody species along an environmental gradient in an African ecosystem.

I am interested in the evolutionary and ecological mechanisms that structure floristic communities. Many of the questions I research have emerged from my observations and experiences in the tropical forests of Indonesia.  These include the following: (1) What are the rules of community assembly and co-existence in tropical rain forests? (2) How can the study of continuous functional traits and environmental gradients be used to determine community structure? (3) How can ecological models be applied to the restoration and management of tropical rain forests?

I am interested in plant ecology and taxonomy. For my undergraduate thesis, I studied plant diversity in relation to the soil properties and the topography in a dry forest in the Madidi National Park of Bolivia. Now as a graduate student, I will be examining how plant traits differ along environmental gradients in the Madidi National Park of Bolivia.

I am broadly interested in ecology and evolution. Topics of particular interest to me are the evolution of lek breeding systems, community phylogenetic signals, the relationship of morphology to species' ecology, and seed dispersal.

My research interests ranges from comparative ecology of plant invasive species to conservation biology and environmental policies. I am interested to investigate how some ecological features like regeneration niches, seed dispersal, important traits for colonization and releasing from enemies act between native and novel habitats of invasive plant species. I want to incorporate this information with spatial models to generate maps of potential distribution of plant invaders in new habitats.
I am also interested in learning how to apply scientific results in ecology to take accurate management decisions in conservation that can influence present and future environmental policies in the New World Tropics, with emphasis in my home country Ecuador.
