My research investigates the psychological and neural processes underlying how we use vision to determine where we are, and how we remain oriented while moving about. To study these issues, I test the perceptual abilities of people from a wide range of ages, including individuals who have suffered certain forms of brain injury. I am especially interested in how the brain constructs representations of object distances at very brief time-scales. Our ability to take in information rapidly can get slowed down by a variety of real-world factors, from fast-moving, high-workload environments to normal aging. I study the impact of these factors on how we localize objects and how our visual system flexibly compensates for these slow-downs.
