Off the clock.

Things that compound. Atlases I couldn't yet read; portfolios I still can't fully predict; a thesis that took 25 years of data to write.

Geography is, in one sentence, the study of why things are where they are. I haven't gotten tired of that question yet.

Fitness

4× a week. Same discipline that finishes a thesis.

02

Travel

Fieldwork with a notebook.

03

Investment

A small personal portfolio. The biggest live experiment in human behaviour.

04

Technology

AI × satellites. Next decade's remote sensing.

Where the data
takes me.

Two questions. One published. One defended.

Methane plume detection comparison: Sentinel-5P vs MethaneSAT
Peer-reviewed · CONF-MSS 2026 · Adana, Turkey

From Pixels to Plumes

The bottleneck is not detection — it's attribution.

~70× finer pixel · ~1000× smaller area · the difference between "something is leaking nearby" and "that facility is leaking."

No actual relationship.

Coastal cities are both wealthier and cooler — a geographic confound. Adaptation budgets followed the wrong signal.

Where I'd like to work

Government Agencies

Environment, land use, meteorology — where evidence still matters.

Universities & Research Institutes

Long-horizon work, peer review, methods you can stake your name on.

Environmental NGOs

Organisations that take the long view and aren't allergic to data.

ESG & Climate Consulting

Where the analysis is honest and the numbers carry consequence.

Get in touch

Let's talk.

If any of this sounds like a fit — for an industrial training placement, a research collaboration, or a graduate programme — I'd love to hear from you.
