This was a good read. It's making me think about how to target other demographics (e.g. people with disabilities, in my case) for similar interventions.

How can we flip the decline in girls and gender-diverse students doing mathematics at higher levels? Zsuzsanna Dancso explains how her program of mentorship and encouragement piloted at @sydney.edu.au increased enrolments from 22% to 30%📈 🧮 More here: doi.org/10.64628/AA.... #MathSky doi.

Thrilled to see that powerhouse Nalini Joshi (@monsoon0.bsky.social) has been named the 2025 NSW Scientist of the Year for her work in geometric & asymptotic methods to study discrete and continuous nonlinear mathematical models Congratulations Nalini! #MathSky youtu.be/XoZO6EKqg68

Next month, the University of Sydney will host two distinguished lectures, by Bob Tarjan and Shafi Goldwasser. I reckon we could say December is Turing-complete.

In October 2025, Fakhteh Ghanbarnejad visited SMRI, as part of our International Visitor Program. In this interview, she talks to us about her work in complex systems and networks, at the interface of physics, applied mathematics and computer science! #MathSky www.youtube.com/watch?v=SsBD...

How can #AI provide a new lens for looking at novel and exciting problems in mathematics? SMRI Director Geordie Williamson's AMS Colloquium Lectures will provide examples of Geordie's own use of AI at the forefront of research #MathSky

Two years ago, I had an epiphany, which led me to pivot my research towards mathematics for quantum era security. We’re nowhere near where I’d like to be yet, but I hope that these tantalizing new ideas will lead us to an unusual new perspective … go.sydney.edu.au/Idtmpn
