Minnan completed her BS and MS in Electrical Engineering from MIT and then joined the lab in 2005.Minnan discovered that stimulus value discounted the motor commands that initiated eye movements, and that a function of the cerebellum was to monitor this variability and compensate for it.  Minnan also discovered that the fast timescale of adaptation was impaired in cerebellar disease.  Finally, Minnan discovered that transcranial magnetic stimulation of the brain could disrupt an ongoing saccade, but that this perturbation was compensated with motor commands that arrived later in the same movement.  She completed a PhD in Biomedical Engineering on May 2010 with the thesis Adaptive control of saccades via internal feedback.She subsequently became a postdoc at the Massachusetts Eye and Ear Infirmary, Harvard University.

 

Her thesis results were published in the following papers:
