Broadly speaking, water is my business. More specifically, I study nonlinear partial differential equations that model (among many other physical phenomena) water waves. I maintain two large lines of research: theoretical and applied. In the theoretical part I study completely integrable systems by inverse spectral and scattering methods in connection with fluid mechanics. In the applied part I collaborate with geophysicists on shallow water waves systems that are used in modeling tsunami waves. For this activity I hire graduate and undergraduate students.
