Nirnimesh (Nirni) Kumar is a coastal physical oceanographer with research interests in wind, wave, buoyancy and tidal forcing driven circulation from the outer-shelf to the surf zone. He uses a combination of in-situ observations and numerical ocean-models to study these processes. His primary focus is on development and application of coupled ocean circulation and wave-propagation models to study nearshore circulation and sediment transport. In addition, he extensively works with field observations from variety of acoustic, conductivity and temperature sensors, and HF Radars.

Nirni's present research focus is on multiple themes like: (I) quantification of surface wave driven tracer exchange (pollutants/contaminants/ sediment/heat) mechanisms from the surf zone to the outer-shelf, (II) use of field measurements and regional numerical model simulations to identify the role of internal waves in modifying inner-shelf stratification and cross-shelf exchange; and (III) continued development of wave-averaged circulation and wave-resolving numerical models for nearshore applications. He has been involved in multiple multi-institutional projects like the Office of Naval Research funded inner-shelf DRI focused at Point Sal, California, and the National Science Foundation funded CSIDE experiment studying circulation in the San Diego Bight region. Nirni joined the Civil and Environmental Engineering faculty at the University of Washington in Fall 2016.
