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 […]

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 […]

 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 […]

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 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 […]

Electrospinning has emerged as one of the most versatile and impactful techniques for producing nanofibers in various applications, including healthcare, biotechnology, filtration, and advanced materials. This seminar offers a comprehensive overview of both the foundational science and the latest advancements that are shaping the future of the field. The talk will cover topics such as […]

VPG Laserone, a successor of IRE-Polus Ltd founded in 1991 by physicist Valentin P. Gapontsev, represents over three decades of scientific leadership in high-power fiber laser technology. The company has established a vertically integrated manufacturing ecosystem in Russia—localizing 85 % of component production and dedicating 25 % of its investments to R&D—to design, develop, and […]

This talk will consist of parts: The first provides an overview of some interesting and challenging problems that have been studied over the past three decades by my research group. These studies span subsonic and supersonic flows and often involve developing or applying advanced diagnostics in difficult environments allowing us to peer into complex, feature-rich […]
