Postdoctoral Research Fellow(UK Visa Sponsorship)

Job Description

Overview of the Role

The University of Sussex is seeking a highly motivated Postdoctoral Research Fellow to join the Systems Neurodevelopment Laboratory, led by Dr Varun Sreenivasan. This position sits at the exciting intersection of developmental neurobiology and systems neuroscience, focusing on how motor cortex development influences and reshapes sensorimotor circuits.

The successful candidate will contribute to cutting-edge research investigating how postnatal brain development leads to functional circuit rewiring, particularly how motor cortical areas expand and integrate into non-motor regions.

This is a hands-on experimental role combining advanced techniques such as in-vivo whole-cell electrophysiology, optogenetics, viral tracing, and behavioural analysis in mice.

Key Responsibilities

In this role, you will:

• Conduct in-vivo electrophysiology experiments during postnatal development
  Apply optogenetic and viral tracing techniques to study neural circuit function
  Record and analyse behavioural data using video-based tracking methods
  Develop, maintain, and troubleshoot experimental rigs and setups
  Manage and organise complex datasets using MATLAB or Python
  Contribute to experimental design, data interpretation, and research publications
  Collaborate with team members and support ongoing laboratory projects
  Communicate findings through presentations, reports, and scientific outputs

About You

We are looking for a researcher who is both technically skilled and scientifically curious. You will ideally have:

A PhD (completed or submitted) in Neuroscience or a closely related field
Practical experience in one or more of the following:

• In-vivo electrophysiology or two-photon imaging
  Optogenetics
  Behavioural experiments in mice
  Strong programming skills in MATLAB and/or Python for data analysis
  Confidence in building, maintaining, and troubleshooting lab equipment
  Ability to work independently while contributing to team-based research
  Strong communication skills for both scientific and general audiences
  Enthusiasm for experimental neuroscience and problem-solving
