I am a Young Researcher of Shanghai AI Laboratory, working with Prof. Wanli Ouyang and Prof. Lei Bai. Before that, I got the PhD degree from Hong Kong Polytechnic University, working with Prof. Xiao-Ming Wu. I also interned at XPixel group in Shanghai AI Laboratory and SIAT-CAS, working with Prof. Chao Dong and Prof. Yu Qiao. In 2018, I got the Master degree from the Beijing Institute of Technology, supervised by Prof. Weidong Hu.

Currently, I lead a team engaged in scientific discovery evaluation and open-source platforms. We have launched the SciPrismax project. Recently, my primary areas of focus include:

Large-scale evaluation: build broad scientific benchmarks for large models and agents.
Post-training algorithm: efficient and simple methods that raise scientific multi-modal reasoning.
Data-centric AI: synthesis and generation of scientific AI data (e.g., QA and CoT) with large models and agents.
Unified scientific model: design foundation model for unified understanding and generation across scientific domains.

Recent Research Highlights:

Large-scale evaluation:
- Multidisciplinary benchmarking: Scientists’ First Exam(Preprint)
- Single-disciplinary benchmarking: OmniEarth-Bench(Preprint), MSEarth(Preprint), EarthSE(Preprint), PhysUniBench(Preprint)
Post-training algorithm:
- Reinforcement learning for weather: Align-DA(Preprint)
Data-centric AI:
- Scientific data extraction: Manalyzer(Preprint)
Unified scientific model:
- Weather unified model: WeatherGFM(ICLR2025)
- Vision unified model: Lumina-omnilv(Preprint), Decouple to Reconstruct(ICCV2025)

If you are interested in the above research topics and would like to join us with Young Researcher, Research Intern or Joint Training Ph.D. Project at Shanghai AI Laboratory, feel free to drop me an email zhangwenlong@pjlab.org.cn. Students with good foundations in AI and science background are appreciated.
