We invite applications for postdoctoral researchers with strong expertise in
in vivo electrophysiology and circuit neuroscience to join our team Neuronal Circuits & Brain Dynamics at the Paris Brain Institute (ICM).

Our project focuses on how neuromodulators (NE, DA, 5-HT, ACh) reshape large-scale circuit dynamics, inter-area communication, and state-dependent reconfiguration across hippocampal, prefrontal, and thalamic networks. Our experiments are designed to generate datasets that constrain mechanistic interpretations.

The researcher will lead experimental work combining:

• high-density extracellular electrophysiology (such as Neuropixels probes)
• neuromodulator readouts (GRAB sensors, fiber photometry)
• targeted perturbations (optogenetics, chemogenetics, in vivo genome editing)
• behavioral paradigms (used to structure internal state transitions)

Required background and mindset

We are looking for an experimentalist with quantitative spirit, deep interest on underlying mechanisms, and hands-on, problem-solving mentality.

• Extensive hands-on experience with in vivo electrophysiology in rodents
  (surgeries, recordings, manipulations)
• Demonstrated ability to independently run complex experiments
• Willingness to modify hardware, software, or analysis pipelines when needed
• Comfortable preprocessing own data
• Understanding spike sorting, quality control, cell-types, circuit motifs, extracellular signals, data organization, and reproducible pipelines
• Data analysis is a core goal, not an afterthought
• Interested in multi-region dynamics, state-dependent computation, and neuromodulation
• Comfort connecting physiological observations to circuit architecture.
• Ability to drive an ambitious experimental project and collaborate with theorists
• Optional but valuable: experience with photometry, 1P/2P imaging, or slice electrophysiology

We strongly encourage applications from individuals that have been traditionally underrepresented in the sciences.

Responsibilities:

• Design and perform multi-region electrophysiology chronic and acute experiments
• Integrate Neuropixels data with simultaneous neuromodulator recordings
• Design, implement, and interpret circuit perturbation experiments
• Generate multi-modal datasets combining behavior, physiology, and neuromodulation
• Collaborate and engage critically with theorists developing multi-level models

Research culture

Research in our lab is driven by the belief that understanding brain function requires quantitative, mechanistic reasoning grounded in high-quality physiological data.

We prioritize careful experimental design, deep engagement with raw signals, and an explicit connection between circuit structure, population dynamics, and computation.

Lab members are expected to take ownership of their experiments and analyses end-to-end, to question assumptions, and to engage critically across disciplines.

Intellectual rigor, technical independence, and clarity of thought are central to the lab’s culture.

Opportunities

As a postdoctoral researcher in our group:

• You will be an integral part of shaping our research direction and team culture. You will engage in exciting and meaningful research and will have access to all the tools necessary to push the boundaries of scientific exploration, with our cutting-edge techniques and state-of-the-art facilities.
