🧪 The Sjöström Lab in Montreal is looking for a postdoc! We study cortical circuits, synaptic plasticity, and NMDAR signalling using custom 2-photon microscopy and optogenetics. We seek candidates with strong patch-clamp and/or 2-photon imaging expertise, and a relevant publication track record.
We are looking for an outstanding postdoctoral researcher to join our team at McGill University. The Sjöström lab studies neocortical circuits, with a focus on synaptic plasticity, NMDA receptor signaling, 2-photon optogenetics, and advanced 2-photon imaging. We are particularly interested in candidates with strong expertise in whole-cell patch-clamp electrophysiology and/or 2-photon imaging, and a solid track record of relevant publications.
Applicants should be experienced with whole-cell recordings and/or cutting-edge imaging approaches. Responsibilities will include performing experiments, analyzing and presenting data locally and internationally, writing manuscripts, and occasionally mentoring junior lab members.
Our lab is based at the Research Institute of the McGill University Health Centre, in vibrant, multicultural Montreal—a city that offers exceptional quality of life. McGill and its neighbouring universities form one of the most dynamic neuroscience communities in the world.
For examples of our current directions, see:
•	Chou et al The Innovation 2025, www.cell.com/the-innovation/fulltext/S2666-6758(24)00173-5
•	Wong et al Neuron 2024, www.cell.com/neuron/fulltext/S0896-6273(23)00767-5
The position is fully funded with a competitive salary. Candidates are also expected to apply for external funding, for which we provide strong support. Opportunities are available for both Canadian and international applicants.
To apply, please send a Letter of Intent, CV, brief research statement, and contact information for three referees to Dr. Jesper Sjöström (jesper.sjostrom@mcgill.ca). In the subject line, include "Postdoc" followed by your name.
Application deadline: July 31, 2025.
