Teaching

Mathematics 1G: Introduction to Algebra, Geometry & Networks (MATHS1016).

Large-Scale Computing for Data Analytics (STATS5083), University of Glasgow, 2025.

Additional information

I was a board member of the One World Seminar on Mathematics of Machine Learning from 2022-25. Have a look at the talk recordings if you are interested.

I am currently an organizer of the Network on Mathematical Data Science for Materials Science. 

I am a Founding Member of the IMA's first Special Interest Group (SIG). Topic: Mathematics for Climate, Environment & Sustainability. 

I am a member of the International Congress of Mathematicians Glasgow 2030 Bid Team.

I am passionate about increasing diversity in postgraduate research programmes in STEM. I am  a Women in Machine Learning (WiML) board member and was General Chair of the WiML workshop at NeurIPS 2024. I co-founded the Piscopia Initiative (piscopia.co.uk) to provide information about how to apply to PhDs and what doing a PhD is like. The events are particularly aimed at women and non-binary people in Mathematics, but anyone is welcome to attend. Check out the https://piscopia.co.uk/contacts/ section for info on related initiatives.
