Post-doctoral Fellow
Laboratory of Molecular and Cellular Neuroscience (Dr. Paul Greengard, head)

A great mystery in neuroscience is why most neurodegenerative disorders do not lead to the widespread loss of all neurons, but rather to the loss of select groups of neurons. To understand this selective vulnerability, it is necessary to compare cell-specific differences between vulnerable and non-vulnerable neurons. To date, this has been hampered by the lack of robust techniques for faithfully profiling cells in complex tissues such as the mammalian brain. Cellular heterogeneity has also confounded the study of the mechanism of action of drugs used to treat common neurodegenerative or psychiatric disorders such as Parkinson's disease and schizophrenia.

To overcome this problem, I have worked with colleagues in the Heintz and Greengard labs at the Rockefeller University to develop a new 'TRAP' methodology that uses genetically-targeted ribosome tagging to purify mRNAs from individual cell types in complex tissues. The TRAP methodology has revealed that even closely related neuronal populations have very distinct mRNA translational profiles. My current research focus in the Greengard lab is to use the TRAP methodology to study the molecular basis of neuroleptic and anti-Parkinsonian drug action.
