Bin Xu, PhD

  • Assistant Professor of Neurobiology (in Psychiatry) at CUMC
Profile Headshot


Research Interests: My main research interests lie in two directions: 1). Identifying genetic mutations with large effects through high throughput deep sequencing. 2). Determining the impact of rare genetic mutations in pathophysiology of major neuropsychiatric disorders using human induced pluripotent stem cells (iPSC) based disease model. We have developed methods for mimicing the developing human brain, named cerebral organoids, to investigate how rare genetic mutations [i.e. 22q11 microdeletion syndrome (Xu et al Nature Genetics 2012); SETD1A (Takata et al Neuron); KMT2B (Meyer et al Nature Genetic 2017)] lead to deficits in neural cells derived from patients with neuropsychiatric disorders, such as autism or schizophrenia, and what should be therapeutically targeted in these conditions.

Postdoc Position: If you are interested in our research and highly motivated to work with us, please email me at bx2105 at with a cover letter describing your previous working experience and career goals and your CV.
