Gregory P. Chini

Prof. Greg Chini joined the Mechanical Engineering faculty at UNH in 1999. Since then, Prof. Chini has also worked as a visiting researcher in the Division of Applied and Computational Mathematics at the California Institute of Technology and in the Theoretical Mechanics Division of the School of Mathematical Sciences at Nottingham University (UK). He is a regular participant in the Annual Woods Hole Summer Program in Geophysical Fluid Dynamics.

Prof. Chini teaches undergraduate courses in Fluid Dynamics (ME 608) and Thermodynamics (ME 503) along with several advanced fluid dynamics and applied mathematics courses, including Waves in Fluids (ME 7/812), Viscous Flow (ME 909), and Asymptotic Methods (IAM 940). In 2007, Prof. Chini was appointed founding Co-Director of the CEPS Ph.D. Program in Integrated Applied Mathematics.

Prof. Chini's research interests are in the allied fields of fluid dynamics and physical applied mathematics. His research involves the mathematical modeling of geophysical, environmental, biological and industrial flows. The existence and stability of coherent features (e.g. nonlinear waves, vortices, plumes, and boundary layers) in such flows are of particular interest. Using hybrid analytical-numerical techniques (e.g. asymptotic, variational, and spectral methods), he aims to develop simplified models of complex fluid-mechanical systems; these models are used for identifying key physical processes and for purposes of prediction, design, and control. His specific areas of interest include:

Geophysical (especially Oceanographic), Environmental, Biological and Industrial Fluid Dynamics
Mathematical Modeling, Asymptotic and Variational Analysis, Bifurcation Theory, Physical Applied Mathematics, Numerical Solution of PDEs
Nonlinear Dynamics, Optimal Transport, and Mixing in Turbulent Convection and Boundary Layers
Elasto-Capillary Phenomena in Biology and Soft Matter, Pulmonary Alveolar Mechanics.
