Graduate Research Assistant
University of New Orleans, LA, USA
(August 2016—present)

Technical responsibilities:

• Performed vibration and aerodynamic analysis of flexible structures including helicopter rotor blade, electroactive membrane, and insect wings by developing the numerical model and by conducting experiments

• Conducted extensive experiments using shaker experimental setup, digital image correlation system, wind-tunnel experimental arrangement, and material testing system for several specimens such as small-scale rotor blade, electroactive membrane and insect wings, and a few 3-D printed parts

• Developed extensive fluid-structure interaction models using commercially available ANSYS and Abaqus package software for analyzing flow behavior and structural response

• Developed finite element models using Solidworks, ANSYS, and Abaqus package software for modal analysis of helicopter rotor blade, morphing wings of hypersonic vehicle, and electroactive membrane

• Performed mathematical and computational analysis of helicopter rotor wake and vortex formation and unsteady aerodynamics

Communication responsibilities:

• Helped advisor to provide periodic reports on research update to agencies including NASA (for an EPSCoR RID grant), Louisiana Board of Regents, and National Science Foundation

• Communicated with experimental equipment and software vendors for regular update and operational troubleshooting

• Participated in meetings of LAMDA (a co-operative agreement between NSF and the universities of Louisiana) and presented research work
