Close ME 800:Special Problems in Mechanical Engineering (ME) 3 credits for the degree of Master of Engineering (Mechanical). Close PAE 800:Product-Architecture and Engineering Design Project Issues of context, methodology, program and fabrication are explored for their possible interrelated meanings and influences on the making of expressive form.  This design studio, which is required for the Masters degree, is offered by individual instructors to students who have successfully completed the core curriculum. Close OE 801:Special Problems in Ocean Engineering (PhD) One to six credits. Limit of six credits for the degree of Doctor of Philosophy. Research & Education Research Dr. Imas' primary research interests are in the areas of numerical hydrodynamics and application of CFD in design. His doctoral research focused on simulation of free-surface turbulent flows around surface-piercing bodies. He is currently involved in research activities related to hydrodynamics of underwater swimmers; interaction of high-speed vessel wakes in a confined seaway; and hydro-mechanics of remotely-operated underwater vehicles in estuary environments. His other research activities and interests, past and present, have focused on contact line models and dynamics for bow-wave flows; free-surface LES; development of SPH algorithms for modeling of breaking waves and free-surface phenomena involving surface-piercing bodies; modeling of supercavitation physics with applications to underwater vehicles; missile aerodynamics; FSI involving vortex-induced vibrations of bluff bodies; and aero-hydrodynamics of high-performance sailing yachts.     Education Ph.D., 1998, MIT Cambridge, MA Hydrodynamics, Department of Ocean Engineering Thesis Title: Hydrodynamics Involving a Free-Surface Body Juncture M.Eng., 1992, Rensselaer Polytechnic, Troy, NY Aeronautical Engineering, Department of Mechanical and Aeronautical Engineering and Mechanics Thesis Title: Design of a High-Speed Iceboat Sailing Craft  B.S., 1990, Rensselaer Polytechnic, Troy, NY Aeronautical Engineering, Department of Mechanical, Aeronautical Engineering and Mechanics Experience & Service Experience Research Associate Professor, Davidson Laboratory, Stevens Institute of Technology, Hoboken, NJ Principal Scientist, Fluid Mechanical Systems Group, Anteon Corporation, Mystic, CT Lead Research Scientist, DeepWater Development Group, Chevron-Texaco Energy Company, San Ramon, CA.
