Seohui Bae 배서희

I'm a research scientist at LG AI Research in South Korea.

At LG AI Research, I'm working on AI systems that model the world, make decisions, and adapt under uncertainty. I completed my bachelor's and master's studies at KAIST, where I was fortunate to be advised by Prof. Eunho Yang.

Research

I study how language models and AI agents can acquire stronger reasoning and decision-making abilities through post-training, interaction, and structured supervision. My research focuses on training models to reason over complex decision spaces, building scalable environments and data for learning, and enforcing structural constraints during generation.

  • LLM Reasoning & Post-Training: Developing reinforcement learning, verifier-guided training, and structured supervision methods for improving reasoning and sequential decision-making. I am particularly interested in understanding which reasoning abilities are trainable and transferable across tasks
  • [P2, P5, P6, C1]
  • Data, Environment & Curriculum Scaling: Building executable environments and generative data pipelines for scalable training, evaluation, and curriculum learning. I study how environment and data distributions can be actively designed to improve model capabilities.[P3,P4]
  • Structured & Constrained Generation: Developing generative and learning methods that incorporate discrete structure, hard constraints, and domain knowledge, with applications to reliable reasoning, planning, and constrained generation. [P7]

I regularly contribute to academic publications and collaborative research projects. I’m especially interested in bridging industrial challenges with generalizable solutions in: RL post-training, constrained diffusion policies, and data and environment scaling.
