Selected work

Work

Six pieces of analytical and policy work from my Postgraduate Diploma in Public Health, with full context for each. They cover different methodologies: health impact assessment, regulatory analysis, applied biostatistics, comparative health systems analysis, health promotion, and policy writing. I completed the diploma with distinction.

Note on context. All six pieces below were prepared as part of postgraduate coursework at the University of Otago as part of my Postgraduate Diploma in Public Health. They are presented here as samples of my analytical writing and methodology, not as live published research.
