01 · RESEARCH

Research

Four directions, one thesis — reliable intelligence operating at scale on real science.

DIRECTION 1 · SCALE

Scaling AI for Science

AI-for-Science in physics at production scale — pipelines on real detector data.

  • JUNO discovery pipelines at production scale
  • Computer vision over detector hit patterns
  • Machine learning for reconstruction & particle ID

DIRECTION 2 · AGENTS

Research Agents

Agents that do research the way researchers do — on a gated, verification-first runtime.

  • Spec-driven execution & skill abstraction
  • Unit / E2E / domain acceptance tests
  • Hypothesis chains & critical experiments

DIRECTION 3 · HPC

High Performance Computing

Making reconstruction and statistical analysis fast — CPU/GPU performance, parallelization, and search-based tuning.

  • Profiling, vectorization & parallelization of the hot path
  • GPU statistical fitting (GooStats / GooFit)
  • Search-based tuning (MCTS optimizer)

DIRECTION 4 · PARTICLE PHYSICS

Particle Physics

Neutrino physics — oscillations and solar neutrinos, from Borexino’s solar program to JUNO’s oscillation measurements.

  • Reactor ν̄ₑ oscillations & mass ordering at JUNO
  • CNO & ⁸B solar neutrinos
  • Statistical methods: BAMBI, multivariate fits, GooStats

03 · PROJECTS

neutrix

A terminal AI agent for complex research tasks. Multi-provider (DeepSeek, GLM, and Claude via the IHEP gateway) behind one OpenAI client, with fast/strong model slots, an async prompt queue, and built-in file & shell tools.

Amber

A transformer foundation model for the JUNO detector: self-supervised pre-training on per-PMT hit patterns, with fine-tuned heads for point-like energy/vertex reconstruction, muon-track reconstruction, and event classification.

Neutrino oscillation playground

An in-browser explorer for reactor ν̄ₑ oscillations — drag the mixing angles and Δm², slide Δm²₃₁ across zero to switch mass ordering, and watch both the survival probability and its Fourier power spectrum respond.
