ACADEMIC HOMEPAGE · SHANGHAI UNIVERSITY
Associate Professor at Shanghai University. My research centres on coupled resonators and linear, nonlinear, acoustic–mechanical, thermal–mechanical, and optomechanical coupling.
INTRODUCTION
I investigate the nonlinear dynamics and intelligent design of micro-electromechanical systems. My goal is to transform rich physical behaviour into reliable, high-performance sensing technologies.
Outside the lab, I enjoy bicycling—a useful reminder that balance is always dynamic.
RESEARCH JOURNEY
A research path shaped by the pursuit of robust sensing, scientific independence, and useful physical insight.
ETHOS · FOUNDATION
My doctoral work at Tohoku University was supported by the JSPS Doctoral Fellowship and the GP-Mech Program Scholarship in 2020. In 2023, I was recognised through Shanghai’s Young Talent Programme. Since joining Shanghai University, I have secured multiple competitive public and industry-funded projects.
LOGOS · EVIDENCE
My work has led to more than 40 SCI and EI publications, over 10 patent applications, and one granted patent in Japan and China. I have led research funding exceeding RMB 1.5 million, connecting fundamental mechanics with deployable engineering solutions.
PATHOS · DIRECTION
I began with highly symmetric MEMS inertial resonators and proposed a tunable, high-symmetry gyroscope architecture. Recognising that this route relies on industrial capabilities often concentrated in large companies, I turned to coupled resonators—where nonlinear physics offered a more open frontier and richer phenomena to discover.
Past: high-symmetry inertial resonators and tunable gyroscopes.
Present: weakly coupled nonlinear resonators, dissipative bistability collapse, complementary Fano resonance, and nonlinear micromirrors.
Next: MHz piezoelectric resonators for low-power applications, nonlinear frequency combs, dispersive and internal resonance, multimode coupling, and acousto-optic nonlinearities.

RESEARCH INTERESTS
From coupled micro-resonators to data-driven structural design and robust inertial systems.
NONLINEAR PHONONICS
This research investigates a nonlinear phononic three-level system in which a middle rotational mode is in 1:2 internal resonance with two outer modes. The rotational mode simultaneously drives a broadband anti-phase continuum and a high-Q in-phase discrete state, generating complementary Fano resonances. Structural asymmetry acts as a symmetry gate to tune energy routing and interference topology, enabling a robust platform for coherent dynamics, signal processing, and sensing.

NONLINEAR DISSIPATION
Nonlinear resonance governs stability boundaries in high-Q micromechanical systems. We demonstrate internal-resonance-mismatch-controlled dissipative bistability collapse in serially coupled micro-oscillators. Independent tuning of an antiphase internal mode activates nonlinear energy transfer without changing drive strength, establishing internal-resonance mismatch as a control axis for nonlinear dissipation engineering and reconfigurable micromechanical switching.

INTELLIGENT ENGINEERING
Repeated finite-element simulations across large design spaces are computationally expensive. We develop a graph-based deep surrogate model that predicts multi-order natural frequencies and mode shapes directly from finite-element meshes. A Graphormer-based processor captures global vibration coupling, while a dual-head decoder predicts frequency, displacement field, and temperature-deviation field. Path-generation algorithms and MATLAB–COMSOL LiveLink generate new resonator structures and large simulation datasets for network training.

ROBUST INERTIAL SENSING
We systematically analyse and experimentally study piezoelectric beam MEMS gyroscopes under acoustic-wave attack, addressing a gap in work that has largely focused on electrostatic tuning-fork gyroscopes. Comparative studies show how large proof masses, low resonant frequencies, and flexible springs can increase acoustic coupling susceptibility. Next, we will study acoustic–mechanical coupling on robotic platforms, including threshold analysis for trajectory interference, acoustic attack combinations, and noise-reduction algorithms.
