Research
I have a keen interest in all things data related, including data capture, processing, process optimisation and automation, database management systems and data warehouses, and machine learning.
I also perform geographical operations on data, such as geocoding, geospatial modelling, and mapping. Typical daily tasks include ad-hoc descriptive statistics, preparing data for further analysis, linking datasets, preparing and running online surveys, automating repetitive processes, and generally finding better ways to solve data problems and keep projects running smoothly.
