Professor, Primary Investigator (PI)

My research is on brain plasticity and visual perception. It's a great time to be doing this work, with new technologies allowing us to address age old questions such as:  How much can experience change what the world looks like to us? What sets the limits on this plasticity? Can we use it to help with visual disorders?

Post Doctorate Researcher

I’m a recent postdoc in the Engel lab. My research interests involve long-term adaptation and neural plasticity of the visual system. More specifically, I am interested in the mechanisms underlying the way that sensory neurons readjust to environmental or physiological changes over long periods of time. My work has largely focused on long-term adaptation to color.

I am currently developing an experiment that investigates long-term adaptation effects on monocular suppression using our augmented reality equipment. I am interested in investigating how neural plasticity influences low-level vision like age-related macular degeneration.

My current project explores long-term color adaptation. What does the world look like with red glasses on? Will the world look "normal" with glasses on after long-term adaptation? We ask participants to wear intense red glasses for 5 days, 1 hr on, 1 hr off a total of 5 times each day. We test twice daily using unique yellow settings. We want to know if the visual system learn to adapt back and forth depending on its color environment.
