Summary
👤
Senior🎓
Top SchoolJiacheng Lin is a CS Ph.D. candidate at UIUC with eight years of research and industry experience applying deep learning to coding, reasoning, drug discovery, recommendation systems, and combinatorial optimization. He currently works as an AI Research Scientist Intern at MiroMind.ai focusing on mid/post-training and evaluation for coding and reasoning models while also conducting research at UIUC. His background spans top labs and companies—Microsoft, Amazon, ByteDance, and Keiji AI—where he shipped applied models for foundational AI, recommendation, and DDI prediction. Earlier work at Tsinghua combined transformers with MILP techniques for variable selection in branch-and-bound and optimization problems, reflecting a rare blend of ML and mathematical programming. He is comfortable transitioning ideas from theory to production, having implemented systems ranging from real-time depth estimation to transformer-based decision modules. Outside the lab, his homepage and GitHub showcase an academic-to-industry trajectory that emphasizes reproducible research and practical model evaluation.
