Who I Am

About Me

A mechanical engineering graduate student at Tsinghua University specializing in laser additive manufacturing, biodegradable biomedical materials, and finite element analysis. My research focuses on 3D-printed metal scaffolds (Mg and Zn alloys) for bone regeneration, investigating how stress modulation affects biodegradation rate and biocompatibility.

With strong skills in CAD modeling, ANSYS simulation, and experimental characterization (EIS, SEM, XRD), I bridge computational and experimental approaches to optimize material and structural design for medical applications. Recognized with the Chinese Government Scholarship (CSC) and multiple academic excellence awards.

My future goal is to pursue a PhD focused on hydrogen embrittlement, corrosion resistance, and high entropy alloys (HEAs) for next-generation biodegradable implants.
