OverviewAI-generated summary
Gerardo Celis's research focuses on the carbon cycle and greenhouse gas fluxes within permafrost and tundra ecosystems. His work investigates the release of carbon dioxide (CO2) and methane (CH4) from thawing permafrost soils, particularly examining the influence of factors such as soil moisture, nitrogen availability, and seasonal variations.
His publications include studies on large winter CO2 losses in the northern permafrost region and direct observations of permafrost degradation leading to rapid soil carbon loss. Celis also contributes to the statistical upscaling of ecosystem CO2 fluxes across tundra and boreal domains, aiming to understand regional patterns and uncertainties. His research extends to methane flux analysis from freshwater wetlands, employing machine learning models for gap-filling and uncertainty assessment.
Celis has a distinguished publication record with 107 total publications and 3,227 citations, reflected in his h-index of 28 and designation as a highly cited researcher. He collaborates with researchers at the University of Arkansas at Fayetteville, including Peter S. Ungar and Benjamin R. K. Runkle.
