About

Hi! I'm Melissa! Here are a few things about me:

  • I have a BSc, PGDipSci, and MSc (First Class Honours) in Statistics from The University of Auckland (the birthplace of R programming!).
  • I have over nine years of programming experience and can program very confidently in R, Python, SQL, HTML/CSS, and LaTeX. I also have experience with JavaScript, MATLAB, SAS, and bash/shell scripting.
  • My favourite areas of statistics are health and ecology, but I like to learn about anything!
  • I have worked in a range of different roles:
    • Information Analyst in the New Zealand health sector, creating R Shiny web tools and producing official government health statistics.
    • Data Engineer at a digital marketing agency, using Google Cloud Platform.
    • Analytics Engineer, developing R Shiny applications for pharmaceutical and cancer research purposes.
    • Data Consultant for an AI company, collecting training data for LLMs and agentic AI assistants.
    • Statistician/Research Analyst for a health economics and outcomes research company.
  • The skills and tools I have used in my professional experience include: R (especially Shiny and the tidyverse), Python (PySpark, NumPy, pandas), SQL, Excel, HTML, CSS, JavaScript, Databricks, Jupyter Notebooks, Google Cloud Platform (especially BigQuery), bash, GitHub, GitLab, Gitflow, CI/CD, Agile development, and various statistical concepts (e.g. GLM/GLMM, ASR, time series).
  • Right now, I'm learning Power BI and AWS. I hope to eventually learn some JS libraries and Swift too! I love learning new tools and programming languages.
  • I grew up in Aotearoa (New Zealand) and moved to Vancouver, BC, Canada in February 2023.
  • Outside of work, I teach tap dancing, draw, hike, camp, and I'm currently learning French! I love to read all kinds of books and I am a big Stephen King fan!

Check out some of my projects, publications, and presentations below!

Ethnic Disparities for Survival and Mortality in New Zealand Patients With Head and Neck Cancer

I co-authored this study to investigate differences in survival and mortality in patients with head and neck cancer in New Zealand.

My involvement included conducting survival analysis, calculating age standardized rates, determining sample size, and more.

Berlin Heart Study Shiny App

I created this R Shiny app for the Berlin Heart Study, to estimate the wait time for a heart donor match for pediatric patients in New Zealand.

The estimation algorithm, which I developed myself, uses the following techniques:

  • Expected value of a geometric distribution
  • Poisson regression
  • Quantile regression with WHO childhood growth standards
  • Clopper-Pearson confidence intervals

While this app isn't available publicly, a screen recording demonstration can be seen at the link below.

Report on Alzheimer's Disease Neuroimaging Initiative (ADNI) data

In 2022, I took STATS 770: Introduction to Medical Statistics as part of my MSc. The project I chose for this course was to examine the relationship between the number of APOE4 gene alleles and the presentation of Alzheimer's Disease and its various stages of cognitive decline.

I received 97% for this report, and an A+ for the course overall.

Math Board Game

I am passionate about math education, and I have tutored high school math students since 2014, both privately and at two different businesses. During this time, I have noticed some key topics that many students struggle with. One common difficulty is finding the gradient of a line when the x- and y-axes aren't of a typical 1-1 scale.

In 2019, for a university course about math education, I made a math version of Snakes & Ladders to help students with this issue. The project received an A+ grade and is now used as an example of project work for students enrolled in the course.

I used a laser cutter and 3D printers, as at the time I worked as a Creative Technologist at a maker space.

In 2024, I have resurrected this project and have begun some improvements and refinements. I hope to eventually learn Swift so that I can make it into a phone/tablet app.

Watch this space for updates!
