Hi there - I’m Sammi! 🚵 🏸 🎷 👩💻
I’m currently a trainer on the Health Service Modelling Associates (HSMA) Programme, teaching public sector analysts, clinicians and managers how to use and apply data science and operational research techniques. I was previously a data analyst, and later data scientist, in a mental health trust in the NHS.
I work with and teach a range of technologies to students on the HSMA programme, specialising in
- discrete event simulation (DES)
- creating and deploying web applications
- geographic visualisation
- location and boundary optimization problems
- tree-based machine learning models
- explainable AI
- reproducible reporting with Quarto
We teach exclusively free and open source software on HSMA - primarily using the Python programming language - and all HSMA training material is released under a non-commercial open source licence, so check out hsma.co.uk/learn if you’d like to work through our teaching sessions, which include all lecture recordings and coding exercises from the full programme, at your own pace. No prior Python experience is necessary - we start from the very beginning!
I have also turned our course content into openly-available eBooks, with free eBooks available so far on
- Python programming for beginners (python.hsma.co.uk)
- discrete event simulation in Python with SimPy (des.hsma.co.uk)
- geographic visualisation and optimization in QGIS and Python (geographic.hsma.co.uk)
- web app development in Streamlit (webapps.hsma.co.uk)
I’m passionate about making the outputs of the techniques we teach easier for stakeholders to understand. To that end, I’m currently working on the vidigi package for visualising patient flow in simulation models or real-world data.
You can find out more about vidigi via my SW25 poster here. Here’s an example of it in action with a simulated emergency department!1
