I am interested in reinforcement learning, believing its potential remains largely underexplored today as both a general learning paradigm and a behavior optimizer. I particularly focus on applying reinforcement learning to large language model post-training, viewing reinforcement learning as a critical direction to scale up models with compute when high quality data becomes increasingly scarce.
