Fridays@4 – From research to market: lessons from an academic founder
Professor Ali El Kaafarani and Sami Walter
Abstract
Please join us for a fireside chat, hosted by OSE, between PQShield founder and visiting professor, Dr Ali El Kaafarani, and Sami Walter, associate at Oxford Sciences Enterprises (OSE).
Dr Ali El Kaafarani is the founder and CEO of PQShield, a post-quantum cryptography (PQC) company empowering organisations, industries and nations with quantum-resistant cryptography that is modernising the vital security systems and components of the world's technology supply chain.
In this chat, we’ll discuss Dr Ali El Kaafarani’s experience founding PQShield and lessons learned from spinning a company out from the Oxford ecosystem.

Mathematrix: Crafts and Chill
Abstract
It’s a busy and stressful term for a lot of us so come and take a break and do some colouring and origami with us. Venting is very much encouraged.

Mathematrix: Diversifying and Decolonising Mathematics
Abstract
We’ll have an open discussion about the ways in which Mathematics is very euro-centric and how we can act, as students and educators, to change this.

Counting solutions to (some) homogeneous quadratic forms in eight prime variables
Aleksandra Kowalska
(University of Oxford)
Abstract
In 2014, Lilu Zhao counted the solutions to non-degenerate, homogeneous quadratic forms in at least nine prime variables, using the circle method. However, while the suggested formula for the number of solutions is believed to hold for forms in at least five variables, his method seems to break for general forms in less than nine variables.
In 2021, Ben Green solved the problem for forms in eight prime variables (using a very different approach), satisfying a 'genericity' condition. The aim of my project was to solve some forms in eight variables not satisfying this condition.
In the talk, I will describe my findings, which allowed me to count the number of solutions to forms in eight prime variables with off-diagonal rank 3 (i.e., which have an invertible 3x3 submatrix without diagonal entries), which is a subset of non-generic forms.
