Thesis

Fun Experience

Turing DSG Hackathon: Detecting Shallow Gas from Marine Seismic Images (Alan Turing Institute: Data Study Group challenge)
Over a week of intense collaboration with a diverse team of participants from all over the world, we:
  • Explored CNN architectures and ensemble approaches for geospatial pattern recognition.
  • Developed classification, segmentation, and object detection models for shallow gas pocket identification in noisy, low-contrast marine datasets.
  • Contributed to the end-of-sprint report for industrial partner BP, presenting results with interpretability-focused visualizations.

Teaching Trips

Data & AI: for pathogen genomics (Philippines, Indonesia, Thailand, UK)
Week-long intensive courses taught at a range of locations to diverse groups of researchers from all over the world:
  • Teaching Bash programming and the use of command-line based software.
  • Teaching the mathematics and biology behind the genomics sequencing pipeline we developed in house.
  • Building a RAG chatbot with LangChain and ChromaDB, grounded in the course content, for interactive participant Q&A.
  • Individual problem-solving workshops: providing AI and bioinformatics solutions to real research problems on a case-by-case basis.
