Extreme Manufacturing

We focus on novel manufacturing and materials processing techniques, such as laser-based manufacturing, ultrasonic processing, additive manufacturing, dielectrophoresis, and more. Based on the understanding of microstructural evolution, phase transitions, pattern formation, thermodynamics and kinetics of materials, temperature/pressure/scale dependent heat transfer through interfaces, and ultrafast dynamics of laser-matter interaction, by using experimental and manufacturing methods such as real-time condition monitoring of manufacturing processes at critical interfaces, nanocomposite additive manufacturing, laser micro/nanomachining, shock peening, forming, welding, and surface engineering.

Research Focus

This research explores ultrafast laser-based processes for enhancing material performance and enabling precision fabrication. Using femtosecond laser shock peening, we investigate how high-energy, localized shock waves can improve surface hardness and fatigue resistance without requiring protective coatings or confinement layers. Through combined experimental and computational studies, we examine underlying mechanisms such as non-equilibrium electron dynamics and extreme strain-rate deformation. In parallel, we study ultrafast laser micromachining of transparent materials, focusing on ablation and material ejection processes to produce high-quality, high–aspect ratio microchannels for applications in micro-optics, electronics, and biomedical systems.
