Jess and Caoimhe

Having met in 2015 at the start of our PhDs in applied maths at the University of Oxford, we bonded over our passion for making maths accessible, promoting its many applications and encouraging girls to pursue careers in STEM subjects.


This led to the creation of mathematigals, an organization to foster diversity among the physical sciences. 

Math and Geometry Tools

Our mission is to answer the age-old maths question

"when will I ever use this?"


encouraging girls to love and pursue careers in maths.


Caoimhe Rooney

Caoimhe was born in Belfast, Northern Ireland and studied pure maths at Trinity College Dublin before undertaking her PhD in applied maths at the University of Oxford. She also participated in the International Space University's Southern Hemisphere Space Studies Program in 2018.

Caoimhe is fascinated by space and how maths can help uncover the mysteries of the universe and is currently a research scientist at NASA Ames Research Center. She studies distant planets called exoplanets with the goal of understanding how they formed, what they're made of and ultimately if they could harbor life.

Motivated by the lack of general knowledge of the endless applications of mathematics, Caoimhe hopes that mathematigals will help banish the misconception that maths is useless by demonstrating how maths is the language of our universe and truly is everywhere.

Jessica Williams

Jessica was born in London, UK, but spent time growing up in California, USA. She studied mathematics and applied sciences - with a specialisation in medical and biological sciences - at UCLA. She moved back to the UK in 2014 to study for a master's, followed by a PhD, at the University of Oxford in applied maths. 


Jessica believes that mathematics provides a toolkit to revolutionise many areas of medical science by quantifying clinical decision-making. Her primary interests lie in fluid dynamics and medical device design. She previously worked as a postdoctoral researcher in the field of cardiology at MIT and Harvard Medical School, and is now a scientist at a medical device company. 

Researchers in the physical sciences (mathematics, computer science, engineering) are comprised of less than 25% women. Jessica hopes mathematigals will help combat this gender gap by encouraging girls to love and become lifelong learners of maths.
