Research Area in Energy:

Energy harvesting from fluid-structure interaction – Harnessing hydrokinetic power from vortex-induced vibration of elastically constrained cylinder arrays in uniform flow has been shown to yield a power density of several hundred W/m3.We make use of a combined asymptotic and numerical methodology to derive/investigate a nonlinear model governing this complex spatio-temporal process and predict/control its optimal performance.

Photothermal energy conversion – Spontaneous vibration of thermo-visco-elastic elements subject to laser irradiation have been used for both sensing and actuation of micro and nano-scale systems which exhibit complex bifurcations including non-stationary chaotic-like dynamics. We investigate the resulting photothermal energy conversion via multiple-scale asymptotics and numerical analysis.


Research Interests:

Renewable Energy Sources [aero/hydro kinetic power harvesting in controllable synchronized multi-element structural arrays].
Energy Conversion [photo-thermal dynamics in nonlinear nano-opto-electro-mechanical systems].
Optical Atmospheric Energy Transmission [high altitude laser source stabilization via tethered lighter-than-air systems].
