As Lab Manager, my focus is on the efficient operation of Zhaoping Li's department as a whole. That means ensuring all of the components run smoothly: students and postdocs work in synergy despite different core projects, equipment and computer programs function properly, protocols and procedures are followed, etc. It also means filling in on different tasks when necessary, for example during personnel transitions. On the science side, my experience in eye movements helps support existing visual psychophysics experiments, as well as open up possibilities for new ones.
I received my B.S.E. in Bioengineering from the University of Pennsylvania in 1995, and my M.S. in Bioengineering/Neuroscience from the Universities of California, San Francisco and Berkeley in 1999, with a focus on neural modeling. I spent the next eight years as a programmer and research assistant in oculomotor neurophysiology at the Smith-Kettlewell Institute in San Francisco, with a particular focus on anticipatory and predictive eye movements. In 2007 I went to Belgium and in 2011 received a Doctorate in Neuroscience from the University of Louvain (Brussels and Louvain-la-Neuve), looking at how the brain processes time and causality. Following my doctorate I worked on the neurophysiology of face processing via human fMRI, and computer-graphics modeling of eye movements. In 2013 I joined the Playable Innovative Technologies Lab at Northeastern University, where we looked the use of games as psychological research tools in order to make deductions about brain processes under more naturalistic stimulus conditions. In 2016 I returned to Smith-Kettlewell, where we used human psychophysics to study the relationship between ocular smooth pursuit and saccades, as well as mechanisms of binocular control and their relationship to strabismus.
