Hi! I'm Rosie 👋

I’m passionate about transformative technology and its potential to radically improve the future.

I’m interested in the intersection of economics and ethics, and more generally in designing systems to achieve good outcomes. I think a lot about systems, productivity, incentive structures, mechanism design, AI, futurism, effective altruism, morality, science, and rationality, among other things.

I’m a Technical Program Manager at OpenAI, where I lead a team of safety specialists working on the responsible use of large language models. Previously, I was Head of Safety-Critical AI at the Partnership on AI, where I focused on responsible publication practices for increasingly advanced AI research. Before that, I was Assistant Director of the Center for Human-Compatible AI at UC Berkeley, and a Research Engineer at BBC R&D. I cofounded Manchester Futurists, and I’ve studied Physics, Philosophy, Computer Science, and Machine Learning. Here is a longer third-person bio.


  • In terms of the big 5, I’m high on openness, conscientiousness, and agreeableness; I’m medium on extraversion and low on neuroticism.
  • I value epistemic rigor; I think it’s really difficult to actually know anything but tools like statistics, Bayes’ theroem, being evidence-based, and understanding cognitive biases can help.
  • I’m fascinated by scams, cults, MLMs, pseudoscience, conspiracies, etc.
  • I’m frustrated by things that aren’t as good as they could be and spend a lot of time reading and thinking about ideas for improving the world.
  • I’m ~90% vegan (the 10% gives me some wiggle room to be pragmatic).
  • I used to attend Berkeley Entrepreneurial Toastmasters but have lapsed during the pandemic.
  • I love bright colors, classic rock music, firepits, bread, and red wine.
  • I enjoy dancing (mostly salsa) and have recently been getting into power-lifting.
  • I have grapheme-color synaesthesia.
  • I often experiment with ways to simplify and improve my life and I procrastinate by reading about productivity.
  • Currently, I’m studying economics and thinking a lot about things like public goods, coordination problems, collective action problems, game theory, etc, and how they intersect with ethics.
  • I live in the San Francisco Bay Area, and am originally from the UK. I enjoy noticing little cultural differences.
  • I occasionally make video tutorials about Roam Research.
