Main

Jonathan Carroll, PhD

I provide software design and implementation for statistics, analysis, visualisation, exploration, curation, transfer, and storage - all things data.

I enjoy solving complex puzzles, both mathematical, algorithmic, and biological. I build tools to ease data flow between storage and scientists.

I am comfortable with a UNIX/Linux environment and a variety of platform ecosystems. I have successfully navigated remote positions since 2017.
