Main Purpose of the Job

The post holder will conduct primary research in the AI for Biology Group to develop generative, causal and decision-making AI methods for biological design and closed-loop discovery.

The role will focus on Bayesian decision-making, experimental design and original AI algorithms for modeling high-dimensional biological design spaces with interpretable and uncertainty-aware representations. Using these representations, the post holder will develop methods to generate testable hypotheses, propose candidate biological designs, prioritise experiments, reason over biological constraints and learn from experimental feedback.

This post will form the design and discovery engine of the Generative Digital Biology programme. Working alongside established foundation model research in the group, the successful candidate will develop methods that connect biological representation learning with generative modelling, reinforcement learning, Bayesian experimental design, active learning, uncertainty quantification, causal modelling, multi-objective optimisation and combinatorial optimisation.

The successful candidate will join at a rare moment: early enough to help shape a new AI for Biology programme at EI, but with strong algorithmic foundations, prior publications, existing collaborations and a clear research trajectory already in place. The ambition is to move beyond models that only predict biological properties, towards AI systems that can propose, refine and prioritise biological designs and experiments.

Application areas may include sequence and RNA design, regulatory elements, perturbation design, synthetic constructs, cellular states, genotype-to-phenotype landscapes, engineering biology, plant systems, human health and therapeutic discovery collaborations where appropriate.

This will be a highly collaborative role embedded across EI. The post holder will work with EI colleagues and platforms to connect AI-designed hypotheses and candidates with biological data, experimental design and validation routes, including potential collaborations with Earlham Biofoundry and engineering biology colleagues on AI-guided design-build-test-learn cycles;
• with Cellular Genomics and Single-cell and Spatial Analysis on perturbation, cell-state and single-cell/spatial omics use cases;
• and with BioFAIR, ELIXIR-UK, Open and FAIR Data and Research e-Infrastructure colleagues on AI-ready design datasets, benchmarks, provenance and reproducible workflows.

The post holder will be expected to lead high-quality research outputs, publish in leading AI, machine learning, computational biology and life science venues, contribute to open and reproducible algorithms, software and benchmarks, and support future competitive grant applications to UKRI, EPSRC, BBSRC, Wellcome, ERC and related funders.

Key Relationships

INTERNAL: Reporting to Professor Ke Li, the post holder will work closely with the AI for Biology Group and collaborate across EI’s research programmes, National Bioscience Research Infrastructures and technology platforms. Key internal relationships are expected to include BioFAIR, ELIXIR-UK, and Open and FAIR Data colleagues; Research e-Infrastructure; the Cellular Genomics programme; the Single-cell and Spatial Analysis platform; Earlham Biofoundry and engineering biology colleagues; Transformative Genomics; High-Performance Sequencing; and relevant EI scientific groups working on plants, microbes, biodiversity, health, genomics and data-intensive bioscience. The role is intended to help make the AI for Biology Group a collaborative AI engine for EI, supporting AI-ready design datasets, generative-design benchmarks, provenance-aware experimental records, model-guided experimental design and closed-loop discovery workflows across the Institute.

EXTERNAL: The post holder will interact with UK and international collaborators in AI, machine learning, computational biology, genomics, single-cell and spatial biology, engineering biology, plant science, human health and therapeutic discovery. External collaborations may include academic, clinical, public-sector, infrastructure and industry partners where appropriate.
