In this two-part talk, I will present an overview of my research over the past ten years in the academia and the industry. In the first part, I will talk about the use of articulated wings for rapid manoeuvring at high angles of attack, particularly with application to landing in constrained spaces. I will present […]

Multi-robot systems can significantly expand our ability to operate in complex and hazardous environments, from disaster response and environmental monitoring to national security. Achieving this requires robotic teams that are scalable, resilient, and capable of safe collaboration with each other and with humans. In this talk, I will present my research toward advancing such autonomous […]

 In this seminar, I will first introduce an empirical four-parameter formula for lift and drag on an airfoil, which shows good fits to experimental data. I will then use this formula to obtain a closed form nonlinear dynamical model of the longitudinal or pitch plane motions of an aircraft. The method of time scale separation […]

Data-driven approaches have generated tremendous excitement in turbulence modeling, but enthusiasm has often outpaced scientific rigor. Many current AI/ML turbulence models lack physical interpretability, exhibit limited generalizability across flow regimes, and do not reflect the true dynamical nature of turbulence. A new strategy is needed—one that leverages AI while remaining fully compliant with the physics […]

Automated Fiber Placement (AFP) is transforming the fabrication of high-performance thermoplastic composites by enabling precision layup of fiber tows with spatially controlled heating and compaction. Yet, the interplay of radiative heating, heat diffusion, and material flow during AFP remains one of the least understood links between process parameters and structural performance. This seminar presents a […]

he constructive role of temporal disorder (random noise) in facilitating responses of nonlinear systems will be explored in this talk, through a combination of experimental and numerical investigations. In particular, nonlinear oscillators and nonlinear oscillator arrays will be considered. These oscillator systems represent models of micro-scale and macro-scale systems and energy harvester systems. It is […]

Air Marshal TD Joseph examines aerospace power as a critical instrument of statecraft, highlighting its strategic, coercive, and diplomatic roles in modern conflict and international relations. The latest example is India itself choosing aerospace power as the first instrument of choice to punish the enemy as in ‘Op Sindoor’. Drawing on historical and contemporary examples […]

Over the past decade, the fluidic pinball has become a valuable benchmarkfor studying flow control strategies. The configuration consists of three independently rotating cylinders positioned at the vertices of an equilateral triangle, with the flow directed perpendicularly to one of its sides. The cylinder rotation rates serve as the control inputs, while velocity sensors located […]

This talk presents a comprehensive overview of advanced fluidic and thermal management strategies across biomedical and defense applications. We begin with a systematic evaluation of Particle Image Velocimetry (PIV), specifically addressing the challenges of simultaneous velocity and particle size measurement. By analyzing Gaussian intensity variations across the light sheet and the optical system’s depth of […]

A mathematical framework is presented to guide the search for Rayleigh waves in lattice materials based on periodic structure theory and the Bloch theorem. Architected materials with a periodic microstructure are distinguished from crystals in continuum anisotropic elasticity by the presence of at least one length scale and a band structure with partial and complete […]
