Gabriel Ferreira, Ph.D.
Research Scientist
Natural Resource Ecology Laboratory
Colorado State University
Dr. Gabriel Ferreira leads the capacity building outreach efforts to support users in the use of ALU and to assist GHG Inventory compilers to estimate emissions and removals in the AFOLU sector. Before joining CSU in 2022, he was a postdoctoral researcher at University of Georgia (2019 – 2021) and Federal University of Lavras (2017 – 2018). Gabriel is Forest Engineer (UFLA) and holds a MSc and PhD in Soil Science from Vicosa Federal University, with two periods as a visiting scientist at the University of New Hampshire and Rothamsted Research. Gabriel’s objective is to leverage his scientific background and experience to promote nature-based climate solutions supported by quantitative data.
