Research Interests

Main goals of my research are (i) to better understand physical and biogeochemical processes in the marine environments, and (ii) to better delineate the responses of the environment to climate forcing, in various temporal and spatial scales. To achieve these goals I utilize physical and chemical analysis methods, analyze large-scale ocean data, and develop conceptual models. I conduct my research with 3 different spatial scopes: (i) global- to basin-, (ii) regional-, and (iii) local-scales. I measure trace gases such as sulfur hexafluoride (SF6) and chlorofluorocarbons (CFCs) in the ocean at ultra-trace level as decadal-scale transient tracers of ocean circulation and ventilation processes. This is to understand basin (i.e. Pacific Ocean) to regional (e.g. Gulf of Mexico) scale processes, and analyze basin-scale ocean data to detect decadal-scale ocean property changes in response to recent climate change.

Sea-going opportunity (closed)
 

We are looking for students and early career scientists to participate in each of two legs of a hydrographic cruise across the North Pacific along 30N on the R/V Revelle. The first leg (~7 weeks April-June 2022) sails from Guam to Honolulu. The second leg (~4.5 weeks June-July 2022) picks up in Honolulu and sails to San Diego. Please find more information about this opportunity here GO-SHIP_P02_2022_Student_Opportunity. Deadline for applications is November 30, 2021. [positions filled @ 12/15/21]
