Dr. Alemu Gonsamo is a Canada Research Chair and an assistant professor of Remote Sensing at the School of Earth, Environment & Society in McMaster University. His research focuses on ground, airborne, and satellite remote sensing of vegetation from the leaf level to the global scale to study plant structural and photosynthetic traits, plant and carbon uptake seasonality, and terrestrial ecosystem primary productivity and greenness. Using long-term global satellite observations, ground measurements and mechanistic computer models, he also studies the impacts of increasing atmospheric CO2 concentrations, climate change and variability on terrestrial ecosystems, and related feedbacks to the atmosphere through carbon cycle. His Remote Sensing lab at McMaster University develops improved satellite remote sensing methods and products for terrestrial ecosystems relevant to the global change studies.
