👨‍🔬 About Me

I am an AI researcher and Director of an AI Innovation Lab, specialising in Retrieval-Augmented Generation (RAG), multi-agent workflows, and multimodal AI applied to healthcare, education, and the public sector.

My work spans end-to-end system design — from embedding pipelines and vector stores through to agentic reasoning and evaluation frameworks — with a focus on deployable, real-world AI in multilingual and resource-constrained environments.

I deliver NVIDIA DLI workshops, advise on applied AI pilots, and lead student research projects at the intersection of NLP, computer vision, and agentic systems.


🔬 Research Interests

  • RAG Systems — retrieval pipelines, chunking strategies, hybrid search, multilingual benchmarking
  • Multi-Agent AI — LangGraph, tool-use, orchestration, agentic decision-making
  • Multimodal AI — medical imaging + NLP fusion for clinical decision support
  • AI in Education — ADHD-aware study assistants, personalised learning agents
  • Graph Neural Networks — fraud detection, knowledge graphs
  • Evaluation & Safety — culturally grounded QA benchmarks, hallucination mitigation
