Professional Experience

Dr. Jachec has an educational background in ocean, coastal and civil engineering specializing in environmental fluid mechanics, coastal engineering. He uses a combination of well-established engineering methologies along with state-of-the-art numerical simulations using high performance computing.

Between Dr. Jachec's M.S. and Ph.D. degrees, he worked for a number of years in industy as a consulting coastal engineer. Projects included: hydrodynamic modeling studies to quantify tidal circulation and estimate residence time; water wave transformation modeling; assessing the impact of offshore sand borrow sites on wave propagation; design culverts and river cross-section to mitigate upland flooding; inlet relocation; and expert witness testimony.

Dr. Jachec is registered professional engineer and is a member of several professional societies that include American Society of Civil Engineers (ASCE), Association of Coastal Engineers (ACE), and American Geophysical Union (AGU).

Current Research

Dr. Jachec's current research includes:

* Performing numerical modeling to simulate the evolution of internal tides and waves within the coastal ocean.

* Assessing the impact of internal tides on mixing off the Orgeon coast.

* Two-phase flow of the water-sediment interface using Large-Eddy Simulation (LES) and Discrete Element Modeling (DEM).
