About me

I am a Data Scientist working at the Christie Hospital in Manchester. The Christie is one of Europe's largest specialist cancer hospitals. My work in involves finding ways to use large amounts of data to improve patient care. I provide statistical modelling support to clinicians conducting clinical cancer research.

My interests lie in the analysis of large complex datasets and I am conducting research into text-mining of electronic patient records collaborating with Manchester University. Techniques I use include elastic net regularised regression, Bayesian hierarchical modelling, GAMs, GLMs and parametric and non-parametric survival modelling. I use the R programming language for most of my analysis.

I have made some shiny apps, I have published some papers and I have given some talks.

I am on Github and Linkedin

Shiny Applications

Shiny is a web application framework for R. It allows users to quickly create interactive web applications based on analysis done in R. I have created a couple of publicly available shiny apps and an R package that makes it even more simple to create predictive shiny apps.

Drug reponse

IL2 app

This app is for predicting patient response to the kidney cancer drug IL-2. It is based on data from 145 metastatic renal cell carcinoma patients.

Job Search

International Jobs app

This app is for finding a job anywhere in the world. It connects to the Indeed API and searches all 54 international indeed websites, returning the results on a map of the world

R Package

predictshine

Predictshine is an R package that allows users to create interactive shiny based web-apps to make predictions about individuals. its main function predictshine() works similarly to the predict() function.
