Research

Nonlinear water waves

To develop theoretical models for the evolution of nonlinear, broadband, multi-directional surface waves.

Strongly nonlinear solitary waves

To study the evolution of strongly nonlinear surface and internal solitary waves in stratified flows.

Hydrodynamic stability

To investigate the stability of stratified flows and periodic waves.

Resoanant wave interactions

To study two-dimensional resonant and near-resonant wave interactions for surface and internal waves.

Surface signatures of IWs

To model the surface signatures of large amplitude long internal waves using nonlinear modulation theories.

Breaking waves

To better undestand wave breaking process and develop a mathematical model for energy dissipation.

Wave-body interactions

To develop an efficient numerical method to study nonlinear waves interacting with bodies.

Laboratory experiments

To perform small-scale wave tank experiments with various wavemakers to generate periodic and solitary waves.

PhD students

To work on research projects on nonlinear waves in fluids, free surface flows, and geophysical fluid dynamics.

Undergraduate Students

Multiple experimental and numeical research internships supported by NSF are available to work in the Water Wave Lab.

Postdocs

A postdoc position starting in Sept. 2023 is available to study nonlinear water waves and their interactions. To apply, send a CV, a research statement, and the names of three references electronically to wychoi@njit.edu.
