Machine learning
2020 to 2026
- Emergent inference-time semantic contamination via in-context priming arXiv:2604.04043 (2026) Five culturally loaded numbers given as few-shot examples shift a capable model's answers to an unrelated prompt toward darker themes. A smaller model does not shift.
- Toward evaluation frameworks for multi-agent scientific AI systems arXiv:2603.26718 (2026) How to benchmark scientific agents when retrieval can pass for reasoning, training data is contaminated, and novel problems have no ground truth. Includes a dataset of new research ideas and interviews with researchers in quantum science.
- Why does in-context learning fail sometimes? Evaluating in-context learning on open and closed questions arXiv:2407.02028 (2024) A context closely aligned with the topic does not always help more than a loosely related one, especially for open, difficult, or novel questions.
- Context matters: data-efficient augmentation of large language models for scientific applications arXiv:2312.07069 (2023) The relation between the relevance of a context and the quality of the answer is not linear.
- Emulating quantum dynamics with neural networks via knowledge distillation Frontiers in Materials 9, 1060744 (2023) An emulator trained on a curriculum of simple examples generalizes to wave packets and potentials it has not seen.
- Inferring topological transitions in pattern-forming processes with self-supervised learning npj Computational Materials 8, 205 (2022) The uncertainty of a network trained on the inverse problem marks where a material's microstructure changes regime, with no labels.
- Performance weighting for robust federated learning against corrupted sources arXiv:2205.01184 (2022) Weighting each participant by measured performance keeps a federation useful when some participants train on corrupted labels.

Decentralized systems
2019 to 2026
- Distributed computer system and method of operation thereof US Patent 12,749,011. Filed in June 2021 with a priority date of June 2020, granted on 29 September 2026. The application was published as US 2023/0316127 A1 (2023), EP 3929742 A1, and WO 2021/260517 A1 (2021) Collective learning without a central coordinator. Worker nodes are grouped into clusters, each cluster trains a model on its own ledger without sharing raw data, and a main ledger coordinates the whole.
- Democratising blockchain: a minimal agency consensus model Presented at Tokenomics 2019, Paris. arXiv:2006.05390 (2020) A consensus protocol that combines a directed acyclic graph with a chain of blocks, so that blocks are built collectively and no round leader can reorder or withhold transactions.
