I am a recipient of
the Academia Sinica Fellowship (2019) and the Sir Charles Clore Postdoctoral
Fellowship (2022) for conducting postdoctoral research in Taiwan and Israel,
respectively. These international research projects were undertaken in Danie
Liang’s laboratory in Academia Sinica and Dan Yakir’s Biosphere -Atmosphere Research
Group at the Weizmann Institute of Science, Israel. My postdoctoral research at
these two institutions included the application of triple oxygen isotopes in
dissolved nitrate to investigate nitrate dynamics in freshwater reservoirs, and
the development of hyperspectral remote sensing technique of sun induced
chlorophyll fluorescence (SIF) as a proxy for gross primary productivity for
semi-arid Mediterranean pine forests.
