Current Graduate Advisees

Oswaldo CarrilloOswaldo Carrillo

  • Degree Sought: PHD
  • Graduate Advisor(s): Yanai and Stehman
  • Area of Study: Forest Resources Management

Personal Statement
Oswaldo Carrillo has a master's degree in applied statistics from the Colegio de Postgraduados, he has 10 years of experience in the area of Monitoring, Reporting and Verification (MRV) for REDD+. He has carried out different statistical analyzes on MRV for REDD+ and has carried out MRV trainings in different countries in Latin America, Africa and Southeast Asia. From 2016 to 2021, he was the head of CONAFOR's MRV system for REDD+, in which he coordinated the preparation of two national GHG inventories in the land sector, a national Forest Emission Reference Level (NREF), a subnational Forest Reference (NRF), a national REDD+ performance report, among others. He is an active member of the roster of experts of the United Nations Framework Convention on Climate Change for the technical assessments of FREL / NRF. Currently, he is a member of the Latin-American and Caribbean SilvaCarbon team (through the US Forest Service) as a “Latin America SilvaCarbon Greenhouse Gas Estimation Statistical Expert” and he is a doctoral student at the Environmental Sciences and Forestry Collage of the State University of New York.
