Short Intro

Full bio→

A highly motivated and aspiring researcher with a strong background in deep learning, with recent work centered on multimodal learning. Over the past few years, I have actively contributed to the field, publishing research articles in top-tier venues such as ACL and WACV. My primary research interests now lie in preference optimization and reinforcement learning for large language models. I have also worked on vision-language models, domain adaptation, and federated learning, and continue to explore these areas with strong interest.

    Adversarial Defense with Preference Optimization (AdPO)

    How AdPO turns adversarial training into a preference optimization problem: a vision-language model learns, with DPO, to prefer its own description of a clean image over its description of an attacked one, and to describe the attacked image as if it were clean.

    Adversarial Policy Optimization (APO)

    How APO makes a reinforcement learning agent robust to high-dimensional and noisy observations: a perturber network learns small changes to the observation that change the agent's actions the most, and the policy network learns to ignore them, in a max-min game on top of PPO.
