About Me

Data Scientist and ML Researcher focused on building interpretable, responsible AI for real world impact. MSc Business Analytics & International Business (University of Dundee). Four peer reviewed preprints in clinical and health informatics. Currently building a research portfolio in causal ML for climate prediction, alongside deep learning projects spanning computer vision and NLP.

What I work on:

  • Causal ML for Climate — PCMCI causal discovery, trend break detection, and causally informed Arctic sea ice prediction
  • Interpretable ML — SHAP, Grad-CAM, explainability pipelines
  • Computer Vision — transfer learning, satellite wildfire classification, coral reef health classification, skin lesion classification (CNN)
  • NLP & Ethical AI — sentiment analysis (RNN), bias detection, text analysis at scale
  • Clinical & Predictive AI — clinical RAG for Parkinson's, clinical risk stratification, churn modelling, survival analysis
  • Research — 4 DOI indexed preprints on Zenodo

Core Competencies:

  • Data Analysis & Visualization
  • Machine Learning & Predictive Modelling
  • Causal Inference & Explainable AI
  • Business Intelligence & Dashboard Development
  • Process Optimization & Workflow Mapping
  • Cross functional Collaboration
