My research focuses on mechanism and machine science, especially kinematic synthesis, analysis, and optimization. Key areas include modular kinematic analysis, over-constrained mechanism synthesis, and novel cam–follower design, aiming to improve analysis efficiency and mechanism performance.

1. Novel Cam-Follower Mechanisms
I investigate novel cam–follower mechanisms to address limitations of traditional designs, including high contact stress and poor force transmission. My work introduces modified followers such as multi-roller followers, symmetric double concave followers, and a modified constant-diameter cam mechanism equipped with symmetrical offset rollers. These designs improve transmission efficiency, reduce contact and side-thrust forces, and enable more compact cam mechanisms. Please see the video below.

2. Synthesis and Analysis of Over-Constrained Mechanisms
I study over-constrained mechanisms, rare devices whose mobility cannot be explained by classical formulas. I developed a systematic synthesis method that avoids complex symbolic computations and led to the discovery of new five-bar and six-bar mechanisms with diverse motion capabilities. My work also explores their industrial potential, where compactness and reduced link count provide practical advantages. Please see the video below.

3. Modular Kinematic Analysis of Planar, Spherical, and Spatial Linkages
For modular kinematic analysis, I developed a method that decomposes complex mechanisms into Assur-based kinematic modules, enabling faster and clearer analysis. The approach provides predefined planar and spherical modules, implementation-ready subroutines, and ongoing extensions to spatial linkages. Please see the video below.
