Hi, I'm Jiacheng Pang.

I build multimodal and multi-agent LLM systems with applications in affective computing and social intelligence.

I am currently a CS(AI) Master's student at USC Viterbi (graduating in December 2025). I am also working as a research assistant at the Intelligent Human Perception Lab, USC ICT with Prof. Mohammad soleymani and Ashutosh Chaubey, where I focus on building and evaluating multimodal LLMs for paralinguistic understanding.

I am also working at the Melady Lab at USC Viterbi with Prof. Yan Liu and Wei Yang on multi-agent collaboration and reinforcement learning.
