EunJung joined the laboratory in 1999 and completed her PhD in Biomedical Engineering on 2004 with the thesis Representation of proprioceptive information for generation of arm dynamics.  She discovered that much of the generalization properties that have been observed in learning of force fields can be attributed to the way that the nervous system encodes proprioception.  Using a model of muscle spindle neurons, she demonstrated that this type of coding accounted for a large body of data in human psychophysics.  She also discovered that there were dissociable contributions from both the implicit memory system as well as the explicit memory system to the process underlying motor adaptation.  She subsequently became a postdoc in the laboratory of Prof. Richard Andersen at Caltech, and is now Project Scientist at University of California San Diego.

 

Her thesis results were published in the following papers:
