About

Hi, I am Sitian Ding.

I am a freshman undergraduate at IIIS, Tsinghua University, building and studying systems around learning, agents, algorithms, and real engineering.

Current Interests

I am interested in reinforcement learning, multi-agent systems, LLM post-training, AI agents, and high-performance algorithms / systems. I enjoy projects that connect algorithms, learning systems, and real-world engineering.

Learning

• Deep Learning, Artificial Intelligence, Algorithms, and Computer Systems
• LLM Applications, high-dimensional probability, graph machine learning, and parallel computing
• Python, C++, PyTorch, basic CUDA, neural network training, LLM post-training, RL self-play, and parallel algorithms

More

• Former chemistry olympiad contestant and National Gold Medalist
• Former informatics olympiad contestant, NOI / Winter Camp Bronze Medalist
• Flute section member in Tsinghua University Military Band

Always curious about intelligence, algorithms, and systems that actually work.
