About me

I am interested in investigating terrestrial vegetation dynamics and its relationships with environmental variables, at diurnal, seasonal, and interannual scales. Various data streams are used in my research, including eddy-covariance flux data, remote-sensing datasets, reanalysis products, and Earth System Models (ESMs)’ output. Besides, I have developed various remote-sensing products based on original satellite retrievals. For example, I have developed long-term high-resolution (0.05 degree) global SIF products using machine learning algorithms, which greatly resolved the limitations of original satellite retrievals (e.g., coarse spatial resolution, incomplete global coverage). I have also established a framework to generate high-resolution (70m) diurnally-resolved LST and ET products from sporadic ECOSTRESS samplings. These products can substantially facilitate vegetation/water monitoring in ecological and agricultural applications.

Outside my research, I like reading books, jogging, hiking and enjoying the beautiful waterfalls around Ithaca.
