Chris Holmes

Senior Data Scientist

Openreach (British Telecom)

I am a senior data scientist specialising in Network Analytics at Openreach Ltd - connecting nearly all homes and businesses in the UK to the national broadband and telephone network.

My professional interests lie in creative problem solving through reproducible and auditable programming, with a major focus on deciphering large and complex data structures to reveal the insight hidden within.

I am an avid user of the R programming language and find it to be an incredibly powerful tool for all aspects of data analytics, from wrangling and visualisation, to statisitcal analysis, predicitve modelling and machine learning. To date, I have developed several personal projects and R packages that examine creative ways of displaying and interpreting information such that it may be understood as simply as possible.

The primary purpose of this blog is to create a single point of reference for my own coding projects, thoughts and ideas. It also serves as a good opportunity to learn a little about static websites and the R blogdown package!

Please feel free to get in touch through the contact link in the top bar or by leaving a comment on any individual post page. I will do my best to respond as quickly as possible.
