Are you eager to do scientific research in Cellular Neuroscience? Would you like to work on human iPSC-derived neurons and CRISPRa/CRISPRi-mediated molecular interventions? Please apply at Vrije Universiteit Amsterdam (VU).
Job description
The Integrative Neurophysiology (INF) division at the Center for Neurogenomics and Cognitive Research (CNCR) at VU offers a fully funded 4-year PhD project. The focus of the project is on elucidating molecular mechanisms of fast neuronal signaling. A critical requirement of fast neuronal computation and cognitive function is the ability of neurons to generate and maintain fast and stable output - action potentials. Because of difficult access to living human neurons, their function in supporting cognition remains largely unexplored. Our lab has extensive experience in studying the function of human neurons from neurosurgery patients. We recently showed that fast electrical signaling in human neurons directly links to cognitive ability in the same individuals (refs 1,2 below). In the current project, we aim to elucidate molecular mechanisms that underlie fast electrical signaling by manipulating expression of specific genes in human neurons, in organotypic slice cultures as well as human iPSC-derived neurons using CRISPRa/CRISPRi (3,4). We will target genes that have been associated with cognitive ability in human subjects (5). Thereby, we aim to reveal what molecular mechanisms enable human neurons to achieve fast cellular computation ultimately supporting human cognition. As a PhD candidate, your research will aim to uncover the cellular and molecular mechanisms underlying fast electrical signaling in human cortical neurons.
The project is funded by an ERC advanced grant awarded to Prof.dr. Huib Mansvelder: https://inf.cncr.nl/research_teams/
Your duties
During the research you use the following approach:
  • You culture human iPSC-derived neurons and organotypic slices of human brain tissue
  • You use CRISPRa/CRISPRi tools to manipulate target genes in human neurons, both iPSC-derived and in organotypic slice cultures of human brain tissue
  • you study electrophysiological recordings and analysis from human (iPSC-derived) neurons in cultures
  • you perform biochemical, transcriptomic and immunohistological analyses of expression in human neurons
Our lab is a part of an inspiring academic environment. In addition to your research, you have an opportunity to participate in teaching. You may also be involved in supervising Bachelor and Master students. You will become a member of the ONWAR graduate school (https://www.onwar.nl ).
