Tianyi Niu
Hello! I am pursuing a Master of Science in Computer Science at The University of North Carolina at Chapel Hill. I am currently a Research Assistant at MURGe-Lab, advised by Prof. Mohit Bansal and Prof. Elias Stengel-Eskin. I am applying to PhD programs starting Fall 2026.
My current research focuses on two key directions:
- Abstractions and Cognition of MLLMs. How do abstractions formed by (M)LLMs differ from humans, and can insights from human cognition inform model development, and vice versa?
- Interaction and communication in multi-agent systems. How is knowledge transferred in multi-agent systems, and can principles of human communication also inform and optimize multi-agent interaction paradigms?
I previously graduated from UNC Chapel Hill with highest distinction, obtaining a BS in Computer Science (highest honors) with a second major in Linguistics. My undergraduate thesis (advised by Prof. Shashank Srivastava) explored whether LLMs benefit from curriculum training on synthetic pre-training data.
