Biography

I am recently joining Korea Insititution of Ocean Science and Technology as a Distinguished Senior Research Scientist. 

I was a Postdoctoral Research Associate at Integrative Oceanography Division of Scripps Institution of Oceanography working with Colleen Petrik. Research topic is to investigate predictability and prediction skills of Fisheries Size and Functional Type model (FEISTY) forced by CESM-FOSI and CESM-DPLE simulations. 

I was a Postdoctoral Research Associate at Geophysical Fluid Dynamics Laboratory and CIMES at Princeton University working with John P. Dunne and Charles A. Stock in Biogeochemistry, Atmospheric Chemistry, and Ecosystems Division. Research topic was to investigate interaction and predictability of climate and marine ecosystem in satellite ocean color, reanalysis and GFDL Earth system model

I completed PhD (Climate Dynamics) in POSTECH, South Korea (Supervisor: Prof. Jong-Seong Kug)

I completed MS (Environmental Marine Science) in Hanyang University, South Korea (Supervisor: Prof. Sang-Wook Yeh)

I completed BS (Environmental Marine Science) in Hanyang University, South Korea

Research

My research backgrounds are climate dynamics and oceanography, which are applying to examine the interactions of climate variability with biogeochemistry and plankton dynamics. My research topics have been diverse and include 1) an assessment of satellite chlorophyll observations to characterize modes of variability and assess opportunities for empirical prediction, 2) multi-model analysis of Arctic biogeochemistry and chlorophyll-climate feedback under climate warming, 3) mechanisms underlying ENSO-biogeochemistry-chlorophyll evolution in GFDL’s Earth system models, and 4) the role of modeled dynamic terrestrial dust variability on ocean biogeochemistry. My current research topic at Scripps Institution of Oceanography aims to understand how much of the interannual variance in fisheries production is explained by climate variability at regional and global scales, how predictable are ecosystem changes, and what are the mechanisms involved.
