When we talk about "seeing the world", we implicitly refer to the people and things associated with the places where we expect to find them. We may take these abilities for granted, but engineers have yet to build a synthetic visual system that performs as accurately, with the level of speed and efficiency as our visual system. My research is devoted to understanding how the brain codes faces and objects. One unresolved question is how the activity of brain cells and their interactions lead to our visual aptitudes. One secret to our visual system's success may be our use of two self-generated signals to enhance face and object processing: (i) our eye movements that actively scan the environment, and (ii) memory from previous experiences.

当我们谈论“看到世界”时，我们隐含地指的是与我们期望找到的地方相关的人和事物。我们可能会认为这些能力是理所当然的，但是工程师尚未建立一个合成的视觉系统，该系统的性能准确，速度和效率水平与我们的视觉系统一样。我的研究致力于了解大脑代码如何面对和物体。一个未解决的问题是脑细胞及其相互作用的活性如何导致我们的视觉才能。视觉系统成功的一个秘密可能是我们使用两个自我生成的信号来增强面部和对象处理：（i）积极扫描环境的眼睛运动，以及（ii）以前的经验中的记忆。
