Case studies from Graduate Data Scientists

Arif Ali

Graduate Data Scientist, Office for National Statistics (ONS), Data Science Campus

I came to the scheme with a degree in Geography (Geocomputation and Spatial Analysis) with geospatial analysis skills in Python and experience in using GIS software.

As a naturally curious person, the sheer breadth of projects within the Civil Service excited me as I knew I would be able to interact with different data science domains. As someone beginning their career, the graduate programme’s focus on learning and personal development also attracted me.

I worked on a COVID-19 project exploring a hotspots risk model and also analysed case studies for the Data Science Campus faculty to provide input into the machine learning course they developed.

I have become a more confident programmer through the graduate programme, and I have learnt a lot from the programme lecturers and the people I’ve worked with. This has helped me to develop my data science skills in new domains, such as machine learning, at pace. The programme has been a great investment in my future data science career.


Rowan Hemsi

Graduate Data Scientist, Office for National Statistics (ONS)

The graduate programme appealed to me because I wanted the opportunity to experience a variety of different data science projects within the public sector.

I had completed an undergraduate degree (BSc) in Mathematics at Durham University, and a Master’s (MSc) in Data Science and Analytics at Cardiff University and came into the programme with a good foundation in statistics and data visualisation, as well as basic Python and R programming skills.

The programme gave me confidence and built on the practical skills needed for a data science project. I helped build the Office for National Statistics’s (ONS) capability in distributed data processing and analysis and used text analysis to automate occupation and industry classification for the Census.

I also had a fantastic opportunity to go on a secondment to 10 Downing Street to work on visualising and communicating data and statistics for senior politicians and advisors.

I was also promoted to a Data Scientist role in the Government Statistical Service’s Good Practice Team.
