Looking For …

实验室持续探索视觉-语言理解中的各类前沿问题，风格自由平等、简单高效，提供充分的科研支持与资源。近期主要关注视觉语言模型的高效表征和安全问题，欢迎对学术有兴趣有想法、敢于探索尝试，有责任心的同学与我交流联系。
打算来读研的同学：每年有很多同学联系我，我知道很大一部分原因是听说我们组氛围比较轻松，但其实我只是在管理上宽松，科研要求并不轻松。我们是纯科研组，我希望给对科研有兴趣且愿意持续投入的同学提供一个和谐支持的环境。我们实验室比较适合未来打算找算法岗或读博的同学，这样才有一致的目标和动力。我也理解大多数同学只想找开发岗或者非技术工作，但请不要只是听说我这里放实习就盲目报考。关于名额，由学院统一分配，我每年预计一个，所以如果觉得自己真的适合请尽早联系。26年全日制已无名额，27年推免生请在接受上大offer后再联系。
I am broadly interested in how humans and machines understand vision and language, with a current focus on efficient representations and safety. I am always looking to connect with motivated students and like-minded collaborators who share similar interests.
