Hyung-Gyu Lim: Dr. Lim is a postdoc in the Petrik research group. He received his PhD in climate dynamics at Pohang University of Science and Technology (POSTECH) in South Korea. He spent three years as a postdoc jointly between the Atmospheric and Oceanic Sciences Program at Princeton University and NOAA Geophysical Fluid Dynamics Laboratory working with Dr. John Dunne and Dr. Charles Stock. Dr. Lim has a strong background in climate dynamics and oceanography, which he has been applying to examine the interactions of climate variability with biogeochemistry and plankton. Past 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. Dr. Lim’s current research at SIO 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.
