Prior to joining MIT in 1999 she held faculty appointments at Yale and Princeton.
She is known for her studies on three-eyed frogs, a demonstration of neural plasticity in which a third eye grafted into a developing tadpole produces a pattern of overlapping connections that resemble mammalian ocular dominance columns.
[1] Using this system, she and her colleagues demonstrated the importance of NMDA receptors in development plasticity.
[2] She currently studies the molecular mechanisms that underlie the brain's response to visual experience.
Her work is also relevant to understanding the mechanisms of schizophrenia and amyotrophic lateral sclerosis (Lou Gehrig's disease).
