Structural Dynamics and Vibrations
Every engineering structure experiences vibrations, and these dynamic effects strongly influence performance, safety, durability, and noise generation. Research in this area focuses on the vibration behavior of beams, plates, shells, and continuous systems, including higher-order modes, nonlinear dynamics, structural stability, and vibration isolation.
Understanding these phenomena is essential in applications such as:
aerospace and marine structures,
precision engineering systems,
earthquake-resistant structures,
and lightweight high-performance components.
The field is particularly exciting because vibrations are not only controlled but can also be intelligently utilized for sensing, wave manipulation, and energy transfer applications.
Viscoelasticity and Vibration Control
Modern lightweight structures are highly sensitive to unwanted vibrations and noise. The group works on viscoelastic materials and constrained layer damping (CLD) techniques for efficient vibration suppression.
Research involves analytical modeling of damping mechanisms in beams and plates, along with theoretical formulations for passive vibration control systems.

This area plays a crucial role in designing engineering systems that are both lightweight and dynamically stable.
Wave Mechanics and Acoustic Metamaterials
Wave propagation in engineered materials is one of the most rapidly growing areas of modern mechanics. Research focuses on linear and nonlinear wave propagation, periodic structures, lattice dynamics, and acoustic metamaterials.
By carefully designing material geometry and periodicity, waves can be manipulated in remarkable ways:
certain frequencies can be blocked,
vibrations can be guided,
and energy can be localized or redirected.
These concepts form the basis of phononic crystals and metamaterials with applications in:

This field combines mechanics, acoustics, physics, and materials engineering in highly interdisciplinary ways.
Vibroacoustics and Underwater Acoustics
Research in vibroacoustics explores the interaction between structural vibrations and sound waves. The group works on structural-acoustic coupling, nonlinear sound–structure interactions, underwater acoustics, and noise control technologies.
These problems are important in:
sonar and submarine systems,
aircraft cabin acoustics,
underwater communication,
and acoustic sensing technologies.
For example, reducing vibration-induced sound radiation is critical in stealth underwater systems, while controlling structural noise is essential for modern transportation and aerospace applications.
Nano Mechanics and Small-Scale Structural Dynamics
At nanoscale dimensions, classical continuum mechanics often becomes insufficient. Research in this area focuses on nonlocal theory, carbon nanotube dynamics, and small-scale structural behavior.
Carbon nanotubes possess extraordinary mechanical properties and have potential applications in:
and ultra-sensitive detection systems.
This area connects advanced mechanics with emerging nanotechnology and next-generation material systems.
Acoustic Sensors and Transducer Systems
The group is interested in the future development and fabrication of acoustic sensing and transducer systems, including:
and piezoelectric transducers.
These devices enable the conversion of mechanical vibrations into electrical signals and play an important role in modern acoustic and sensing technologies.
Potential application areas include:
underwater imaging and sonar,
structural health monitoring,
and communication technologies.
This research direction combines acoustics, materials engineering, electronics, signal processing, and fabrication techniques, offering opportunities for both theoretical investigations and experimental development.
The group also intends to pursue collaborative research with experts from related disciplines such as electronics, materials science, instrumentation, signal processing, and manufacturing in order to develop practical and feasible acoustic sensing and transducer systems.
The future of engineering will increasingly rely on intelligent control of vibrations, waves, acoustics, and sensing systems. Technologies such as acoustic metamaterials, advanced sonar systems, wave-guiding structures, vibration isolation platforms, and nanoscale dynamic devices are expected to play major roles in aerospace, marine engineering, robotics, healthcare, and advanced manufacturing.
Our research group aims to contribute toward these emerging technologies through a combination of theoretical understanding, computational modeling, and experimental innovation.

and emerging technologies in metamaterials and advanced acoustic devices.
The group particularly welcomes students who are curious about how physics and engineering come together to create real-world technologies. Whether it is understanding how a structure vibrates, designing a hydrophone for underwater sensing, or developing materials that can manipulate sound and waves, the research offers opportunities to work on scientifically deep and technologically impactful problems.
