PROFESSIONAL EXPERIENCE

Senior Research Scientist, Dynaflow Inc., Jessup, MD, 07/10-02/11

• Fluid-Solid Interaction (FSI) research of under water explosion near a propeller: US ONR project. GEMINI/DYNA3D coupled in simulations; composite material made propeller with different fiber orientations and properties (polymer, rubber, carbon, Kevlar and glass) and different detonation amount, depth and angle positioning to the propeller. Stress, defection and failure analysis for optimum design.

• Erosion of materials due to cavitating flow: particle modeling interfacing with bubble dynamics data to simulate hydraulic force driven material erosion.

Research Assistant Professor, University of Mississippi, Oxford, MS, 03/07-06/10

• Fracture of materials under extreme loads: DHS project “Nano-Particle Reinforced Composites for Critical Infrastructure Protection” ($1.2 M). Particle modeling, stochastic modeling, AUTODYN, LS-DYNA and PFC2D applied for impact/penetration investigations of polymeric materials (nylon6,6, vinyl ester, epoxy and nano-enforced), fire protection and retrofitting infrastructure design with multi-layered graded materials.

• Loose sand foundation erosion due to plunging flow: DHS project “Structural, Material and Geotechnical Solutions to Levee & Floodwall Construction & Retrofitting” ($2 M). FLOW3D applied for the investigation of New Orleans’s levee system failure during Katrina 2005 with its foundation failure due to overtopping flow; pursuing optimum design. One-week training of FLOW3D at Santa Fe, NM.

• Flooding forecast and assessment: USDA project. Shallow water flooding code developed to produce flooding forecast and assessment. GIS DEM terrain data employed.

• Proposal writing, course teaching, management of proposal design, supervising junior researchers.

NSERC-COREM Postdoctoral Researcher, McGill University, Canada, 09/05–03/07

• Dynamic fragmentation of materials (comminution, high-speed impact, blast, etc.): NSERC-COREM project. Thermal particle modeling developed and applied to investigating thermally-induced fracture of rocks; fracturing rocks with microwave modeled for visualizing, managing, creating and analyzing for developing high-efficient fracturing devices; valuable conclusions obtained; stochastic modeling of material developed. Computational efficiency optimized. One-week training of MPI at McGill University. Research proposals, reports writing.
