Fred Marbach completed his PhD in Tony Zador’s group at Cold Spring Harbor Laboratory, where he investigated the role of auditory cortical outputs in mice trained to make simple auditory-guided decisions. To further pursue his interest in simple sensory-guided learning and behavior, he joined the Stephenson-Jones group at SWC in 2017 as PostDoctoral researcher. Here, his research focuses on how animals learn to predict good and bad outcomes. A simple example is a sound frequently followed by a reward: the animal will learn to expect the upcoming reward upon hearing the sound. To track down this reward expectation, the project focuses on the interplay of the Basal Ganglia and the midbrain Dopaminergic system, attempting to find specific pathways and cell types that mediate this learning.
