I am a Colombian plant ecologist with a background in tropical communities. My research focuses on understanding the effects of natural, and anthropogenic filters on the functioning of tree communities. One of my goals is to study how climate change and environmental variation is changing the structure and functioning on the Andean forests across space and time. For this, I use the trait-based approach as a tool to understand the effect of this climate variability on tree diversity. Another critical point of climate change is the accelerated rate of urbanization, and how the urban development affects the tree functional diversity. Using tropical and temperate cities as a natural laboratory, I try to understand how humans have changed the functioning and the structure of different type of forest.
