- Use of fossil plants as indicators of paleoclimatic and paleoecological conditions.

Current Research

During my PhD studies I plan to explore issues on flowering plants evolution and the origin of Neotropical rainforests. The early stages of diversification of flowering plants, the main components of modern tropical forests, occurred during the Cretaceous (from 142 to 65 million years ago), a period of very active tectonics and redistribution of landmasses that resulted in global temperatures and sea levels much higher than today. However, the plant fossil record from the Cretaceous of northern South America is very scarce and little is known about the initial stages of diversification of Neotropical forests prior to the Cretaceous/Paleogene boundary (K/T). During the next years I will be investigating the plant fossil record of the Cretaceous of northern South America (mainly Colombia), where I think I might find a valuable record of the coordination of ecosystem’s evolution and climate change in a globally warm world. Understanding the earliest phases in the origin of Neotropical forests and how they were affected by changing geography and climates, beginning in the Early Cretaceous, is crucial for understanding the initial assembly of these hyper-diverse plant communities. Understanding the origins of Neotropical forests is also central to understanding the evolutionary diversification of the many plant groups that achieve their greatest diversity in these plant communities. Moreover, comparing vegetational patterns before and after the end-Cretaceous major extinction event may also be relevant to understanding the present day climate change/diversity crisis scenarios.
