Data science: Analysis of big data sets, especially Bayesian methods, computer vision and machine learning.I am a data scientist with 20 years of research experience originally in astrophysics. I am driven by a desire to solve challenging problems in creative ways. In the scientific context this means confronting big data with statistical models. This has given me the opportunity to publish more than 60 articles in major journals.My main focus has been on developing novel statistical algorithms, especially Bayesian ones, predominantly in Python, to process, analyse and model large data sets. I have co-constructed multi-million-pound telescopes to observe faint signals from radiation in the early Universe, giving me a detailed understanding of signal processing and systematic factors affecting the analysis of data streaming from complex environments. I am used to designing robust statistical experiments and working in large teams.
