My research asks a practical question: how can we design flying machines that are more capable, adaptable, and reliable outside the ideal conditions assumed in textbooks? I work at the intersection of aerodynamics, flight mechanics, mechatronics, and fabrication, with particular interest in small unmanned aerial vehicles, rotorcraft, and flapping-wing aircraft inspired by birds and insects. A central challenge is that small aerial vehicles operate in a world dominated by gusts, turbulence, limited onboard power, uncertain sensing, and tight constraints on size and weight. I study how the shape, motion, and control of a vehicle interact with the surrounding air, and how these interactions determine whether it remains stable, manoeuvrable, and energy-efficient. This includes aerodynamic modelling, stability and control, and fluid–structure interaction, especially where wings or other components deform substantially during flight. Flapping-wing vehicles are a useful example. Unlike a conventional fixed-wing aircraft, a flapping wing both generates lift and propulsion through a continuously changing, flexible motion. Understanding such systems requires combining mechanics, unsteady aerodynamics, actuation, sensing, and control. The aim is not simply to imitate nature, but to identify design principles that can make compact aerial robots useful in confined, cluttered, or difficult-to-access environments. My work also emphasizes turning ideas into working systems. I use system integration, reverse engineering, manufacturing, prototyping, and flight testing to connect analytical models with real vehicles. This matters because an elegant aerodynamic concept has limited value unless it can be built, controlled, repaired, and operated reliably with realistic materials, electronics, and energy sources. The broader motivation is to expand what aerial platforms can do: inspection of infrastructure, environmental observation, search and rescue, scientific measurement, and other tasks where conventional aircraft may be too large, fragile, expensive, or inflexible. By treating flight as a coupled problem of air, structures, mechanisms, sensors, and control, I aim to develop aerial systems that are not only novel, but genuinely deployable
