About Me

Guillermo's biosketch: He received his B.Sc. from EARTH University (Costa Rica), and his Ph.D. from Purdue University (Indiana, US). He previously worked as an agriculture and soil science professor at University of Panama (Panama), as a postdoctoral researcher with USDA-ARS at the National Laboratory for Agriculture and the Environment (Iowa, US), and as a scientist with Plant and Food Research Institute (New Zealand). Guillermo has been working at UAlberta since 2012.

He received the Inspiring Young Scientist Award (2014) of the American Society of Agronomy - Environmental Quality Section.

He received the Ed and Peggy Tyrchniewicz Award for Innovation in Teaching (2019) by the Faculty of Agricultural, Life and Environmental Sciences (ALES) – University of Alberta.

Soil Science Education and Research at University of Alberta since 1919.


Guillermo leads the Sustainable Land Ecosystems Research Group 

As a research group, the foci encompass carbon, nitrogen and water cycling and dynamics in land ecosystems. For example, we examine sources, transformation, utilization, behavior, fate, and fluxes of carbon and nitrogen in land ecosystems (often also called agroecosystems) with particular focus on the relative responses, controlling factors, and feedbacks of greenhouse gas exchange and soil carbon sequestration to common and improved management options. Furthermore, field to landscape strategies for sustainable management, greenhouse gas mitigation, climate change adaptation, enhanced resilience of soil and whole ecosystems, improved nutrient and water use-efficiencies, and increased ecosystem services in agricultural systems are also subject of investigation. We aim to deepen, underpin, and extend the existing scientific knowledge on these relevant research areas in order to gain insights, to discover and establish principles, and ultimately to provide solutions for current challenging problems faced by the local, regional and global societies including environmental quality, natural resources conservation, and food and energy securities. Moreover, this collective work contributes to inform process modelling efforts, life cycle assessments, and provide the foundation for the development of policy towards carbon-negative and carbon-neutral systems.

The Research Group is currently integrated by six PhD students, two MSc students, two undergraduate students, two research assistants and one postdoctoral fellow. The alumni include seven graduates, fourteen undergraduates, eight assistants and one visiting professor. The background of the laboratory members includes Canada, Korea, Singapore, China, Bangladesh, Sri Lanka, India, Nigeria, Pakistan, Iran, Ghana, Germany, United Kingdom, United States, Peru, and Mexico. We continue enriching this diversity in our membership as we are open to applicants from all nations and backgrounds.
