Maria Uriarte – Principal Investigator


Maria Uriarte is a Professor in the Dept. of Ecology, Evolution and Environmental Biology at Columbia University. She also serves as adjunct faculty in the Dept. of Ecology, University of São Paulo, Brazil. Prof. Uriarte studies the processes that drive forest dynamics in tropical regions, with a focus on forest recovery after natural disturbance events (hurricanes) and human land use and the consequences of these dynamics for ecosystem services. Her current projects are based in Puerto Rico and Brazil.

Andrew Quebbeman – Ph.D. Student


Andrew received his B.S. from the University of Michigan in Ecology and Evolutionary Biology. His PhD research focuses on identifying the local effects of tree species and topography on spatial patterns of soil greenhouse gas fluxes and nitrogen cycling in the forests of Puerto Rico. He is generally interested in understanding how variation in soil biogeochemical processes at small spatial scales affects our estimates of these processes at the ecosystem scale.

Jazlynn Shaydra Hall – Ph.D. Student


Jazlynn received a BS in Geography and a BA in Anthropology from the University of Wyoming. Her current interests are in identifying relationships between vegetation, extreme climate events, and water resource provision in Puerto Rico. She is utilizing geospatial techniques, remote sensing and field estimates to study the effects of droughts and hurricanes on forests and the subsequent impact on ecosystem services.

Pedro Ribeiro Piffer – Ph.D. Student


Pedro is a biologist from Brazil. He received his BS from University of São Paulo and his MSc in Ecology from State University of Campinas. Pedro has over four years of experience as an environmental consultant in the private sector in Brazil. For his PhD research, he is using remote sensing to quantify reforestation and analyze forest persistence in the Brazilian Atlantic Forest. He is also studying the conflict between land use choices and water resources in his home country.

Roi Ankori-Karlinsky – Ph.D. Student


Roi is an ecologist from Jerusalem. He got his B.A. from Bennington College in Evolution and Ecology, and has worked as a research assistant at Harvard Forest and the Hebrew University of Jerusalem. His current interests are in understanding how droughts and hurricanes change the competitive playing field in forests, identifying how variation in functional traits can dictate resilience to disturbance events, and in turn, impact community composition.

Eva Arroyo – Ph.D. Student


Eva received her BA in mathematics at Duke University with a focus in how probabilistic mathematics could be applied to the study of tropical forests. After graduating, she spent a year at the Smithsonian Tropical Research Institute in Panama studying liana-induced tree mortality. She is interested in how individual variation in heterogenous landscapes can be incorporated into theories of community assembly and how these then interact to create resilience to disturbance in tropical forests.

Melissa Salva Sauri – Research Technician


Melissa is from Puerto Rico and graduated from the University of Puerto Rico in both Biology and Industrial Microbiology. Her research interests are in tropical forest dynamics, focusing on hurricane recovery, and plant-microbe interactions. She spent the past three years working as a tropical forest research technician in Puerto Rico and is currently working in several projects in the Uriarte Lab. She plans to apply to graduate school in the near future.

Sam Farrar – Research Technician


Sam received a B.S in Ecology and Environmental Science from University of Maine in 2017 and for the past year he has worked as a research technician based in Puerto Rico collecting field data and conducting lab work on projects being conducted by the Uriarte Lab. He is interested in disturbance ecology and environmental restoration and is planning to apply to graduate programs in the next year.
