Research interests:
    I use Direct Numerical Simulations (DNS) and Large Eddy Simulations (LES) to study internal waves and turbulence in environmental flows. My current projects involve turbulent mixing in ocean surface mix layers specifically in the Equatorial Undercurrents (EUC) In the Pacific Ocean and the Bay of Bengal in the Indian Ocean.
