Job Details

Job title: Postdoctoral position (Lee Lab, Unit on Functional Neural Circuits)

Employer: National Institute of Mental Health (NIMH), National Institutes of Health (NIH)

Location: Bethesda, Maryland, USA

Description: A postdoctoral position is available in Lee lab (Unit on Functional Neural Circuits). 

My lab studies the organization of neural circuits that enable corticocortical communication and support the computations of dynamic interactions between sensory and behavioral functions using rodents and non-human primate (marmoset). To comprehend how the neocortex integrates and contextually computes relevant incoming information, a mechanistic understanding of the recruitment and role of the various cellular and circuit elements within the corticocortical communication is imperative. We aim 1) to unravel the circuit mechanisms, at a neuronal resolution, through which diverse internal states are transmitted and integrated in relevant brain areas, 2) to determine the behavioral significance of these circuits, 3) to understand the computations they perform, and 4) to explore how such circuit mechanisms emerge during development and adapt through experiences. We focus on motor-sensory processing in somatosensory cortex and connected brain areas of the mouse. We use a combination of methods, including diverse imaging, in vitro and in vivo electrophysiological recordings, optogenetics, chemogenetic, genetic labelling and anatomical tracing, genetic analysis and computational analysis. 

We are looking for highly talented and motivated postdoctoral fellows who have a MD/PhD or PhD in Neuroscience or related disciplines and who have a record of research productivity. We are particularly interested in candidates who have strong quantitative and programming skills and experience in at least one of the following tools: imaging, electrophysiology (in vitro and/or in vivo), and behavioral study. Scientific creativity and communication skills are also important as the candidates will work both independently and as part of a team. Salary will be commensurate with education and experience.
