Research Project:

1) I am using source imaging methods to improve the spatial resolution of EEG and better understand what is occurring in the brain during sleep and waking.

2) I am looking at a measure of entropy called Multiscale Entropy, to examine the complexity of the sleeping and waking brain as well as differences in entropy between control and psychiatric subjects. This work may eventually help with the diagnosis of various disorders as well as shedding light on the neural substrates that give rise to the complex phenotypes of psychiatric disorders.
