I am Junhan Wang, a senior undergraduate in Information and Computing Science at the School of Mathematics and Statistics, Northwestern Polytechnical University, and an incoming PhD student in Mathematics at HKUST.

I pursue both the highest academic excellence and the tangible impact of ideas brought to life—to advance society and benefit humanity. 我既追求学术的卓越与深度，亦笃行于成果的落地生根，以惠社会、益人类。

• Northwestern Polytechnical University, B.S. in Information and Computing Science, expected June 2026
• Incoming PhD student in Mathematics, The Hong Kong University of Science and Technology

Machine Learning     -> interpretable prediction, heterogeneous models, robust evaluation
Causal Inference     -> mechanism discovery, economic interpretation, decision support
Safe RL              -> constrained control, residual guidance, high-frequency decision systems
Applied Mathematics  -> numerical modeling, nonlinear dynamics, optimization-oriented thinking

• National Scholarship
• Knowledge-Action Scholarship
• Special Scholarship for Scientific Research and Innovation
• Innovation and Entrepreneurship Star
• Gold Prize, China International College Students' Innovation Competition
• Gold Prize, Challenge Cup China College Students' Entrepreneurship Competition
• Top Prize, National Robotics Championship & International Humanoid Robot Olympic Games

This profile will gradually publish research code and reproducible artifacts around:

• safe reinforcement learning and constrained decision-making
• interpretable machine learning and causal analysis
• mathematically grounded simulation and optimization workflows
• tools that turn research prototypes into inspectable engineering outputs
