Research Interests

My main research interest lies in the analysis of satellite imagery to assess vegetation response to climate variability. I'm interested in applying time series analysis over satellite data sets to evaluate the spatial and temporal variability of vegetation productivity across different ecosystems in response to predicted climate change. We are investigating how satellite-derived vegetation greenness indexes can be applied in large-scale studies on ecosystems functioning. Also, I'm looking to continue the multi-site research approach as we have done it until now and willing to collaborate on more projects that require intensive data analysis to study ecosystems.
