Research Associate in Backpropagation-Free Learning for Physical Neural Networks

Research Associate in Backpropagation-Free Learning for Physical Neural Networks

We are recruiting a Research Associate to develop learning algorithms that train physical neural networks without backpropagation.

The hardware is nonlinear and analogue: nanomagnetic, nonlinear nanophotonic, and nanoelectronic.

You will build forward-only and contrastive learning rules that train these systems in situ, and the physics-aware models needed to develop them.

You will lead the algorithmic direction of the project.

• What you would be doing
• Design, implement and benchmark backpropagation-free training algorithms for nonlinear physical neural networks: contrastive learning, forward-forward and self-contrastive rules, physical Kolmogorov-Arnold networks, and related architectures.
• Port these algorithms across three hardware substrates (nanomagnetic, nonlinear nanophotonic, nanoelectronic) and find the substrate-independent principles that make forward-only learning work on real devices.
• Build physics-aware differentiable surrogate and digital-twin models, including neural ODEs, to develop and stress-test learning rules alongside experiments.
• Develop noise-aware and hardware-aware training that closes the sim-to-real gap on stochastic, drifting devices.
• Publish in leading venues, present internationally, and help win follow-on funding
• What we are looking for
• A Ph D (awarded or imminent) in physics, engineering, computer science, applied maths, or a closely related field.
• Original work on backpropagation-free learning. Ideally you are first author on a novel learning algorithm.
• Published experience across nanomagnetic, nonlinear nanophotonic, and/or nanoelectronic hardware.
• Hands-on experience with physical Kolmogorov-Arnold networks and other emerging non-MLP architectures.
• Physics-aware surrogate and digital-twin models, including neural ODEs, and noise-aware training for stochastic analogue devices.
• Expert scientific Python (Py Torch or JAX) and a record of reproducible, released code.
• What we can offer you
• Lead the algorithmic core of an ambitious physical-computing programme spanning nanomagnetism, nanophotonics and nanoelectronics, within an international collaboration.
• The opportunity to continue your career at a world-leading institution and be part of our mission to continue science for humanity.
• As a member of research staff you have 10 development days to use to develop your skills and explore your career prospects
• Sector-leading salary and remuneration package (including 43 days off a year and generous pension schemes).
• Be part of a diverse, inclusive and collaborative work culture with various staff networks and resources to support your personal and professional wellbeing .
• Further information
