Research Interests:

Application of the U.S. Navy’s HYCOM model to quantify depth-integrated salt transports in the dynamic northern Indian Ocean. Comparison with other numerical models and reanalysis products were completed in an attempt to identify misrepresentation of transports by the model data in both time and space.

Application of the Aquarius and SMOS datasets to quantify SSS variability on seasonal and interannual time scales. 

Developed a novel technique of combining satellite-derived SSS with in situ subsurface salinity measurements in an attempt to get a more robust estimation of vertical salinity stratification on monthly time scales in the tropical oceans.

Developed unique Madden-Julian Oscillation (MJO) identification criteria in order to observe its formation over the southwest tropical Indian Ocean; a region with highly variable thermocline depth and strong connections to remote forcing such as El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD).

Analyzing interannual variability in Arabian Sea mini warm pool oceanic variables, such as SST, total integrated heat content, and barrier layer thickness, and its relationship to monsoon intensity. The effects of the strong El Niño of 2015-2016 on this relationship are of particular interest. 

Performed regional validation of Aquarius and SMOS data in the important Agulhas current by comparing it to in situ Argo floats data. High accuracy makes the satellite-derived SSS data better for monitoring surface salt advection between the south Indian and Atlantic Oceans than Argo floats data. 

Developing a satellite-based estimation of surface salt advection through Agulhas leakage. This will make the satellite data useful for monitoring potential changes in global climate due to the effect that this leakage has on Atlantic Meridional Overturning Circulation (AMOC).
