Greg Appelbaum is currently a postdoctoral fellow in the Woldorff Laboratory in the Center for Cognitive Neuroscience at Duke University. He completed his PhD under the mentorship of Dr. George Sperling at the University of California, Irvine and held a previous postdoctoral fellowship at the Smith-Kettlewell Eye Research Institute in San Francisco in the laboratory of Dr. Tony Norcia. His research interests primarily concern the characterization of brain mechanisms underlying visual perception and attention. In this work he combines psychophysical measures of behavioral performance with Electroencephalography (EEG) and Functional Magnetic Resonance Imaging (fMRI). He is actively involved in methodological developments relating to the integration of frequency domain EEG (frequency tagging) and high-resolution anatomical MRI for the purpose of assessing the dynamic properties of cortical networks.
