I'm Andreas Varotsis, police officer and quantitative crime scientist with the Metropolitan Police Service.
I also help coordinate Police Rewired, a community of volunteer professionals with an interest in policing technology, community safety, and fighting crime.


I try to use empirical approach and multi-disciplinary, quantitative tools to understand, diagnose, and propose solutions to crime and policing questions.

My particular areas of interest are:

  • econometrics and economic modelling
  • data-science and machine learning
  • crime and police activity in physical space
  • experimental and quasi-experimental testing
  • rapid technological solutions and innovation

I use this site to showcase my recent work, and discuss new data-science and statistical tools and techniques on my blog.
