Research Focus

Machine Learning for Scientific Data

Machine learning researcher and engineer working on AI for Science, physical inverse problems, multimodal learning, and biological data. Currently an ML research intern with the Hallou Group at the University of Oxford, developing models that infer per-cell stress tensors from microscopy images. Available for a six-month final internship beginning in January 2027.

Research Experience

Oxford, Inria, and applied machine learning work for scientific and biomedical data.

Machine Learning Research Intern

University of Oxford — Hallou Group
Oxford, United KingdomJun 2026 – Aug 2026
  • Developing deep learning methods for a physical inverse problem: inferring per-cell stress tensors directly from microscopy images of cellular tissues.
  • Designing and systematically evaluating local-global architectures that combine pretrained vision encoders with cross-attention to fuse cell morphology and tissue-level context.
  • Building a reproducible PyTorch experimentation pipeline spanning synthetic data generation, distributed multi-GPU training on Isambard-AI, controlled ablations, and model diagnostics.
