PhD Researcher · AI for Science · Agents

Hi, I am Encheng Su.

I am a PhD student in Artificial Intelligence at the University of Science and Technology of China, advised by Prof. Wanli Ouyang and Prof. Houqiang Li. I am currently a research intern at Shanghai AI Laboratory.

My research focuses on AI for Science and LLM agents. I build scientific reasoning benchmarks, evaluation tools, multimodal models, and long-horizon agent systems with structured memory. My broader goal is to make AI scientifically rigorous, dependable, and useful in real research workflows.

Questions that I am especially interested in:

  • How can AI reason reliably under scientific constraints, evidence, units, and processes?
  • How can agents use memory, tools, and feedback over long-horizon tasks?
  • How can multimodal systems transfer across disciplines and real-world scientific settings?

Previously, I spent one year in a research internship at UCLA (Aug 2024–Aug 2025), working as a Research Assistant with Prof. Debiao Li on longitudinal breast MRI and AI for Medicine. I also worked as a Researcher at BAAI (Mar–Sep 2025), where I focused on AI4Medical. Earlier research included 3D vision at CUHK/HKCLR, AI for Science at Microsoft Research Asia, and work with Prof. Alois Knoll at the Technical University of Munich.

BRIDGE: Selective Boundary Repair with Dependency Graph Evidence in Multi-Agent Systems

Encheng Su*, Pengze Li*, Ziheng Hua*, Qiucheng Yu, Jianyu Wu, Chen Tang, Yizhou Wang, Lintao Wang, Junjia Xiang, Xinzhu Ma, Xi Chen, Shixiang Tang, Houqiang Li, Xi Chen, Aoran Wang

* Equal contribution.

BRIDGE uses dependency graphs to locate handoff failures in multi-agent workflows, selects repairs using calibrated evidence, and verifies each repair before releasing it. It improves task completion while limiting unnecessary interventions and token overhead.

PROTEAN: Beyond De Novo Generation — Can LLM Agents Perform Text-Guided Protein Structure Editing?

Encheng Su*, Xinping Liu*, Yizhou Wang, Bozitao Zhong, Pengze Li, Jianyu Wu, Mingxiao Li, Xinzhu Ma, Aoran Wang, Liang Hong, Wanli Ouyang, Chen Tang, Houqiang Li, Shixiang Tang

* Equal contribution.

PROTEAN benchmarks text-guided protein structure editing across 380 subtasks in six intervention families. It separately evaluates geometric compliance and biophysical realizability, revealing scope leakage and refolding failures as major bottlenecks for LLM-driven design agents.

SciIF: Benchmarking Scientific Instruction Following Towards Rigorous Scientific Intelligence

Encheng Su, Jianyu Wu, Chen Tang, Lintao Wang, Pengze Li, Aoran Wang, Jinouwen Zhang, Yizhou Wang, Yuan Meng, Xinzhu Ma, Shixiang Tang, Houqiang Li

SciIF evaluates whether models can satisfy the explicit constraints that make scientific answers rigorous—not only produce a plausible final answer. It provides structured verification for conditions, units, assumptions, and required solution processes.

ADT: All-Atom Diffusion Tokenizer for 3D Molecular Structures

Xuantuo Huang, Encheng Su, Aoran Wang, Pan Tan, Shengyong Xu, Yizhou Wang, Chen Tang, Shixiang Tang, Mingxiao Li

ADT encodes small molecules with one structural token per atom and proteins with one token per residue, jointly preserving backbone and side-chain geometry. A diffusion decoder recovers all-atom structures from these compact representations, supporting both reconstruction and autoregressive molecular generation.

Coupled Harness–Model Evolution for Scientific Equation Discovery

Pengze Li, Jiaquan Zhang, Encheng Su, Yunbo Long, Zihang Zeng, Xinping Liu, Han Zhang, Junchi Yu, Shixiang Tang, Aoran Wang, Xi Chen

This framework improves an executable tool library and an LLM's tool-use policy through shared, verifiable fit-error feedback. Failure-driven tool development and training on successful trajectories complement each other to improve scientific equation discovery.
