Esther Florin, Ph.D.

Esther Florin is now Lichtenberg Assistant Professor at Heinrich-Heine University Düsseldorf, Germany. For up to data information please visit the following page: https://sites.google.com/site/estherflorinneuro

During her time at the MNI she worked in the Dynamic Neuroimaging Laboratory with Sylvain Baillet. Her primary interest is in time series analysis and its application to neural data of healthy humans, epilepsy as well as Parkinson patients. Currently her work focuses on identifying the electrophysiological basis of the fMRI resting state activity in healthy humans and alterations due to Parkinson’s disease.

She holds a M.S. from the University at Buffalo, The State University of New York and obtained her PhD at the Research Center Juelich, Germany, working on Granger based causality analysis. She tested the applicability of frequency based multivariate causality measures for physiological data and applied them to local field potentials from Parkinson patients.
