I'm finishing a physics PhD on the QTNM experiment, where we use quantum sensors and machine learning to try to pin down the mass of the neutrino.
I grew up in the UK, and I'm based in London. I care about thinking clearly under uncertainty, which shows up in physics, in machine learning, and in the ordinary decisions that make up a life. Most of what I write circles that theme from one angle or another.
A small origin story
This site is the offspring of a short-lived blog I ran during the summer of 2019, between the first and second year of my physics degree. I toiled on it, was never quite happy with the result, and pulled it down. Now, nearing the end of the PhD, I feel more at ease putting thoughts in public. The version you're reading is the second attempt, a little older and a little less self-conscious.
Now
Writing up my thesis. Reading more and scrolling less. A fuller live status lives at /now.
Writing cadence
A new post every Sunday morning. Essays, analyses, or shorter notes. The easiest way to stay in the loop is the email list below.
Outside work
Exercise is a daily anchor: parkrun most Saturdays, cycling, swimming when the weather is on my side. I spend as much time as I can with family and friends, travelling or trawling through rough trade on a weekend, hunting for something worth listening to on a long walk home. I cook, I write code for fun, and I have a small, persistent compulsion to make the tools I use a little sharper than they were yesterday.

Email is the best route: hello@nathanhigginbotham.com. I read everything. Also on LinkedIn and GitHub.
