My research focuses on understanding the physical processes governing ocean circulation, upper-ocean mixing, and climate variability across a broad range of spatial and temporal scales. I combine theoretical analyses, high-resolution numerical modeling, satellite observations, and oceanographic field measurements to investigate multiscale ocean dynamics and their role in the Earth system.

My long-term research goal is to improve the understanding and prediction of ocean circulation and climate variability by integrating physical theory, observations, numerical models, and emerging data-driven approaches.

Research Themes

🌊 Submesoscale Ocean Dynamics

Submesoscale fronts and filaments regulate vertical exchange, restratification, tracer transport, and upper-ocean circulation. My research investigates the mechanisms governing frontogenesis, ageostrophic circulations, and multiscale interactions between mesoscale and submesoscale motions.

Current research includes

• Frontogenesis and frontolysis
• Ageostrophic circulations
• Vertical tracer transport
• Ocean mixing
• Lagrangian coherent structures
• Subduction processes

🌊 Near-Inertial Waves and Ocean Mixing

Near-inertial waves represent one of the primary pathways through which atmospheric energy enters the ocean interior. My work investigates how near-inertial waves interact with submesoscale fronts and vorticity gradients to enhance ocean mixing, tracer transport, and energy transfer.

Current research includes

• Wave–front interactions
• Inertial pumping
• Wave energetics
• Ocean mixing
• Tracer transport
• Internal wave dynamics

🌏 Equatorial Ocean Dynamics

Equatorial oceans support a rich spectrum of wave motions that influence regional circulation and climate variability. My research combines numerical modeling, satellite observations, and in situ observations to investigate equatorial Kelvin waves, Rossby waves, and upper-ocean variability in the Arabian Sea and the Indian Ocean.

Topics include

• Equatorial Kelvin waves
• Rossby waves
• Arabian Sea dynamics
• Monsoon variability
• Indian Ocean circulation

🚢 Oceanographic Field Observations

Field observations provide an essential bridge between theory and numerical modeling. I have participated in multidisciplinary oceanographic expeditions involving hydrographic observations, CTD deployments, ADCP measurements, and upper-ocean process studies.

These observations are used to validate numerical models and improve our understanding of ocean circulation and mixing.

💻 Numerical Ocean Modeling and Environmental Data Science

Numerical models provide a framework for investigating multiscale ocean dynamics under controlled conditions. My research combines process-oriented numerical simulations with environmental data analysis to study ocean circulation and climate variability.
