• Ph.D. University of Le Havre, 2001

An expert in experimental fluid mechanics, Dr. Goharzadeh obtained his Ph.D. at the University of Le Havre in France (2001). His Ph.D. subject was focused on the experimental characterization of Laminar-Turbulent transition in the rotating fluids. He particularly studied the laminar-turbulence intermittency and published his results in several international journals. After his Ph.D. he joined the prestigious Max Planck Institute for Marine Microbiology in Bremen (Germany) as scientific researcher. He joined a multidisciplinary team in order to understand and model complex bio-physic mechanisms at the bottom of seas and oceans. He characterized experimentally the flow at water-sediment interface. Using the Particle Image Velocimetry (PIV) and Refractive Index Matching (RIM), he measured the velocity of fluid particles at fluid-porous interface and estimated the thickness of the transition layer (Brinkman Layer Thickness) inside the transparent porous media.
