An incomplete list of some projects that we have worked on within our RSE group.
Collaborative work with research groups
The Vaccine Impact Modelling Consortium
The Vaccine Impact Modelling Consortium coordinates the work of several research groups modelling the impact of vaccination programmes worldwide. We provide the technical infrastructure for this project, including
- a web-based system for collecting, verifying and storing many gigabytes of modelling results
- a reproducible-research system, orderly for the project scientists to work with this data
- interactive data visualisation
- a web-based system for disseminating results
An R Shiny web interface for a model that estimates the proportion of people living with HIV who are aware of their status given national or regional data. For use by countries to estimate how close they are to the UNAIDS 90-90-90 target
A web interface for a model estimating various HIV epidemic indicators, see the project page for more information.
Custom data collection app
We developed a custom data collection Android app for use in a health economics field survey. The need for a custom app came from innovative survey questions that could not easily be represented in a conventional form or existing app - they seek to capture a spread of belief allocation across an exhaustive answer space. The code for this is not open due to the confidential nature of the survey.
cinterpolate - interpolation from C, for R
A small utility R package for interpolation (piecewise constant, linear and spline) from C for use within R packages
cyphr - easy to use encryption for R
A high-level approach to make using encryption from R more accessible; the
cyphr package wraps the
sodium packages to provide a common interface, along with abstractions to make encryption easier for data analysts.
(This is also an rOpenSci package.)
dde - an R package for solving delay differential equations
dde package solves delay differential equations (DDEs), which are an extension to ordinary differential equations (ODEs) where the derivatives depend not only on the current state but also on the state at some point in the model’s past. They turn up modelling contexts (e.g., the number of people bitten by mosquitos 10 days ago).
jsonvalidate - JSON schema validation for R
(This is also an rOpenSci package.)
odin - high level differential equations
A “domain specific language”, hosted in R, for representing and compiling ordinary differential equations.
odin is being used within the department for research on malaria, measles, HIV and flu.
orderly - lightweight reproducible reporting
A lightweight system for reproduducible reporting, in R. Composed of an R package,
orderly and a web application, OrderlyWeb,
orderly makes it straightforward to associate analyses with their inputs, version outputs and organise and distribute everything with a user-friendly front-end. The researcher-friendly framework makes very few restrictions on how analyses are carried out.
vaultr - an R client for Vault
Public Engagement Tools
We have a collection of tools for use in science festivals, public engagement events and internal socials, where we explore epidemiological ideas with games and hands-on experiments.
- Barcode epidemic - where an epidemic is spread by passing unqiue QR codes.
- Microbit epidemic - where an epidemic is transmitted over Microbit radio
- Zombie Spatial Simulator original and simplified - visualisation of an individual-based spatial epidemic.
- Herd Immunity - explore vaccination efects in an epidemic simulated by bouncing balls off each other.
