Investigating the physiology of dopamine neurons in pre-clinical Parkinson's Disease

2016-2017
Spring

Mahalakshmi Somayaji is a postdoctoral research scientist at the department of Molecular Therapeutics, Columbia University, New York. She obtained Ph.D in Biochemistry, Chemistry and Pharmacy from Goethe University, Frankfurt, Germany. The main research focus during her graduate studies was in the development of experimental mouse models relevant to Parkinson disease (PD) and to understand the etiology of PD. She investigated the physiology of dopaminergic (DA) neurons, the loss of which results in the onset and pathogenesis of PD. Her research was the first to identify the precise anatomical localization and in vivo physiology of DA neurons, to understand differential pre-symptomatic vulnerability in response to stressors in PD. Her postdoctoral research includes understanding the synaptic physiology of DA neurons in the pre-symptomatic mouse models of PD and to investigate the role of DA pathway in regulating appetite.
