Founder
Facthink LTD
- Since May 2026, building Graph-Hypoth, a multi-agent hypothesis generation system that develops research claims into candidate hypotheses and literature-grounded experiment plans.
- Seven specialised agents work over a shared claim graph to review evidence, propose and critique hypotheses, and design experiments, with fixed aggregation rules and versioned records for audit.

PhD Researcher
Imperial College London, Department of Electrical and Electronic Engineering
- Used representation dimension to estimate language model performance after structural pruning.
- Developed a unified taxonomy of matrix and tensor factorisation for generative language model compression.
- Compressed GPT-series models with tensor decomposition and deployed them on resource-constrained devices, including Raspberry Pi.
- Applied membership inference to dataset legitimacy assessment in MLaaS; this work was featured by the Montreal AI Ethics Institute.
