Introduction
I work on fluid-structure interaction (hydroelasticity) of marine lifting surfaces. The current focus is computational modeling for passive hydroelastic tailoring of lightweight composite lifting surfaces with broad applications in high-speed vessels and energy harvesting.
My research interests are in aero- and hydromechanics, multi-functional composite structures, and ship design.

The introduction of composite materials to the construction of high-performance surface craft in the past two decades has pushed the operating limits in appendage design. For vessels with any kind of lifting surface, composite hydrofoils can be hydroelastically tailored to be more hydrodynamically efficient in off-design conditions due to load-depe...
Composite materials provide greater freedom to tailor load-dependent deformations in lifting surfaces for improved hydrostructural efficiency across the operating envelope compared to metallic counterparts. For foils operating at high speeds, the trade-off between minimizing drag and avoiding cavitation and structural failure is a critical design c...
Well-designed hydrofoils improve ship resistance and seakeeping by lifting the hull above the water. With greater speeds come greater loads, and the two-way interaction of structural deflections of lifting surfaces on the hydrodynamics must be considered. Tailored structural anisotropy can improve hydrodynamic and structural efficiency of lifting s...

Predicting and controlling the steady and dynamic hydroelastic performance is a crucial challenge in marine composite lifting surface design. Excessive flow-induced vibrations and accelerated fatigue can be severe issues if not considered in the initial design. Most design optimizations only consider steady performance and neglect critical dynamic...
Imperfectly scaled models are commonplace in aerodynamics and hydrodynamics because few facilities can meet all the flow and structural scaling requirements. The objectives of this work are to (1) derive and numerically validate scaling relations for the steady-state and dynamic hydroelastic response and stability of hydrodynamic composite lifting...
The ability to extract quantitative flow information from photographic images of the velocity field using Particle Image Velocimetry (PIV) is a powerful alternative to the more traditional invasive or integrated method techniques. The usage of PIV allows the complete characterization of the flow field, and not just at discrete points. Additionally,...
