Ready to transform your complex data challenges into actionable insights? As a PhD statistician with 12+ years in academia (2013-2025) and a Bachelors + Honours in Psychological Science, I bring a unique combination of technical expertise, and communication skills to your projects.

Limited Consulting Opportunities Available

I’m currently accepting select clients for new projects. My tailored approach includes:

• Discovery: Complimentary call to understand your specific needs
• Customised proposal: Clear deliverables, timeline, and pricing structure
• Flexible engagement: From one-time consultations to ongoing partnerships

Services I Offer

Data Solutions

• Data Analytics & Visualisation: Implementing techniques I’ve refined through developing the widely-used visdat and naniar packages (with 2M+ downloads), which help make data exploration intuitive and revealing.

• Statistical Modelling: Applying approaches developed during my PhD, and refined while maintaining the greta package for statistical modelling at The Kids Research Institute Australia.

• Missing Data Analysis: Leveraging methodologies I pioneered in the naniar package to uncover insights hidden in incomplete datasets. The accompanying paper to this work has been cited over 200 times since 2023.

Technical Development

• R Package Development: Creating robust, user-friendly statistical tools following practices that have led to multiple successful rOpenSci-reviewed packages. I have been teaching how to develop R packages since 2016, and recently delivered a course, “R package essentials” on this topic.

• Research Software Engineering: Combining my intimate understanding of research with my programming skills, I can translate methods into software (see for example, conmat for use in infectious disease modelling), and develop reproducible workflows, (see geotarget package for geospatial pipelines, which I developed alongside collaborators Eric Scott, and Andrew Gene Brown).

• Code Review & Optimisation: Applying principles refined through years of collaborative development and maintenance of open-source statistical software. I can help make your code easier to read and maintain, and improve how quickly your code runs.

Knowledge Transfer

• Teaching: Building on experience as a university lecturer in data analysis and business analytics at Monash University. I can deliver courses on the Tidyverse, Quarto, R package development, data visualisation, data analytics, exploratory data analysis, general R programming skills, using git and github, and developing reproducible pipelines using targets.

• Mentoring: I can meet with you or a small group on a regular basis to develop customised material and code review, so you can improve your data analytic skills.

My Approach

1. Understand: Applying active listening techniques from my counselling training to fully grasp your challenges
2. Analyse: Examining your data and processes to identify opportunities for improvement
3. Develop: Creating tailored solutions using state of the art methods
4. Implement: Providing clear documentation and knowledge transfer
5. Refine: Iteratively improving solutions based on feedback and results

Real-World Impact

My work extends beyond academia into practical applications:

• Supporting infectious disease modelling during my time with Prof. Nick Golding’s team (2021-2025)
  • An author of the Doherty Institute Modelling Report to advise on the National Plan to transition Australia’s National COVID Response.
• Developing optimisation solutions with maxcovr for resource allocation problems.
  • In my PhD I developed methods to identify new locations for Automatic External Defibrillator (AEDs) in Switzerland.

About Dr. Nick Tierney

Beyond my technical work, I completed the 4,270km Pacific Crest Trail hike in 2023, demonstrating the same persistence and problem-solving approach I bring to complex data challenges. This experience reinforced my belief that careful planning, adaptability, and determination are key to successfully navigating both wilderness trails and data landscapes.
