Data Analyst.
[Me - SJ Olsen]Background
I'm a data analyst with a background in chemical engineering and six years of hands-onresearch experience across UCL, Alba Nova Labs, and NanoMeli Labs. I started out in the lab, running calculating and running chemical synthesis, validating experimental data, and building reproducible pipelines long before I called it "data work".
These days I apply that same scientific rigour to business problems: digging into datasets, modelling outcomes, and making complex results legible to people who don't live in spreadsheets. I work across the full analytical stack and I care as much about how findings are communicated as how they're derived.
