I’m Johan Zhang, a passionate researcher and engineer specializing in mechanical and acoustic metamaterials, composite materials, and multiphysics simulation. With a PhD in the field, I focus on designing smart materials and structures that achieve programmable mechanical and acoustic performance through computational modeling, advanced simulation, and hands-on experimentation.

Education & Research

• PhD in Mechanical/Acoustic Metamaterials – Focused on programmable shape-morphing structures, broadband acoustic absorbers, and simulation-driven design.
• Master’s & Bachelor’s in related engineering disciplines, with deep training in mechanics, composites, FEA, and manufacturing.

Core Expertise

• AI/ML Frameworks & Expertise: Proficient in machine learning frameworks including PyTorch and TensorFlow.
• Simulation & Modeling: Proficient in COMSOL, ANSYS, ABAQUS for multiphysics FEA (acoustics, mechanics, thermal, electromagnet).
• Programming & Automation: Skilled in Python, MATLAB for simulation scripting, data analysis, and workflow automation.
• Design & Optimization: Experience in parametric design, topology optimization, and ML-aided material design.
• Prototyping & Manufacturing: Hands-on experience with CNC, 3D printing (SLA, FDM, SLS), composite fabrication, and experimental validation.

What I Bring to the Table

I bridge simulation and real-world application—turning concepts into functional prototypes. Whether designing a ventilated acoustic silencer, a shape-shifting mechanical metamaterial, or a biocompatible scaffold, I value:

• Systematic, knowledge-driven development
• Cross-disciplinary collaboration
• Clear documentation and reproducible workflows

Selected Projects

• Optimization of ventilation silencers using Helmholtz resonators
• Programmable mechanical metamaterials for tailored deformation
• 3D-printed scaffold simulation for biomedical applications
• Composite defect analysis and z-pin reinforced laminate studies

Awards & Recognition

• 1st Prize, SAMPE International Super Lightweight Student Contest
• Multiple academic scholarships and “Excellent Student” awards
• Published author in APL Materials, Advanced Engineering Materials, and other SCI journals
• Presenter at top conferences including ICTAM (the “Olympics of Mechanics”)

Beyond Research

In my daily life, I enjoy:

• Tech Blogging – Writing about research tools, simulation tips, and quantum graph theory
• Photography & Travel – Capturing landscapes and cultures worldwide
• Archery, Swimming & Video Games – Balancing focus, fitness, and fun
• Continuous Learning – Currently exploring ML-aided metamaterial design and multiphysics simulation
