My research focuses on several aspects of partial differential equations: mathematical modelling, theory and scientific computing. All motivated by a concrete application. I am particularly interested in waves in fluids. I enjoy very much teaching and interacting with students. I have supervised many PhD and MSc students: https://www.genealogy.math.ndsu.nodak.edu/id.php?id=33196
