I have been interested in how humans brain process visual motion information and how vision is used in movement control. In particular I am exploring the specific mechanisms that underlie motion perception, including both object motion (e.g., an oncoming car), and the motion of the visual environment experienced as a result of the observer's self-motion (e.g., walking and driving). In order to conduct my behavioural research, I have developed a state-of-the-art virtual reality (VR) technology system. What makes this approach revolutionary is that VR allows for the real-time manipulation of dynamic visual environments - something that is practically impossible to achieve in a real world scenario. This research program has not only allowed me to explore fundamental perceptual principles underlying visuomotor control, but it can also be employed in the design of better standardized tests and training/rehabilitation for drivers/pilots and the design of car, road sign and driving/flight simulators.

我一直对人类大脑如何处理视觉运动信息以及视觉如何用于运动控制感兴趣。 特别是，我正在探索运动感知的具体机制，包括物体运动（例如，迎面而来的汽车），以及由于观察者的自运动而经历的视觉环境的运动（例如，步行和驾驶）。 为了进行我的行为研究，我开发了一个最先进的虚拟现实（VR）技术系统。 这种方法的革命性之处在于，VR允许对动态视觉环境进行实时操作-这在真实的世界场景中几乎不可能实现。 这项研究计划不仅使我能够探索视觉控制的基本感知原则，而且还可以用于设计更好的标准化测试和驾驶员/飞行员的培训/康复以及汽车，路标和驾驶/飞行模拟器的设计。
