His initial research at the Natural History Museum, London focussed on biodiversity informatics including work relating to implementing Biodiversity Information Standards (TDWG),[1] and building systems for the broader community including development of the Scratchpads virtual research environment[2] and the eMonocot project.

It was during this time he discovered the museum's library of recorded insect sounds and begin the process of digitising these to make them available via the BioAcoustica project,[3] and separately began work on open hardware sensors for environmental monitoring.

In 2017 Baker became a researcher in the Electronic Engineering faculty at the University of York combining his interest in sensors and entomology to design devices for the automated recognition of the songs of orthoptera in the field.

He has subsequently collaborated with historians at the university on the archive of the Anti-Locust Research Centre held at the Natural History Museum, London.

Baker was involved in Sophie Scott's Royal Institution Christmas Lectures in 2017 demonstrating hissing cockroaches.
