At the University of Oxford, our team is leading research into the origins of galactic and intergalactic magnetic fields using the National Ignition Facility (NIF) laser at the Lawrence Livermore National Laboratory (LLNL). Outside of research, I am a strong advocate for women in physics, a science communicator, and lover of both rock climbing and tiny puppies (in nearly equal measure).
Using the largest laser on Earth, the National Ignition Facility, we can recreate powerful astrophysical events such as supernovas in the laboratory to evince turbulent dynamo– a phenomenon that explains the ubiquitous magnetisation of the universe.
We have experimentally shown that scaled protogalactic magnetic fields can be generated in a laser-produced shockwave and then amplified with turbulent motions to explain field structures found in Cassiopeia A and the Coma galaxy cluster. For exceptionally hot, collisional plasmas, we can even amplify fields towards equipartition of kinetic and magnetic energy– turbulent dynamo.
Magnetic fields are like the invisible glue that helps keep objects in the universe together. For instance, the large fields associated with galaxy clusters play a role in the formation of compact objects such as stars and galaxies.

In the highly male-dominated field of physics, women can often feel limited in their potential due to a lack of female role models and propensity for imposter syndrome. Furthermore, there are severe issues with retention of women in science after higher education.
To target concerns of isolation and imposter syndrome, I created the Oxford Women in Physics Society in an effort to cultivate a welcoming network of supportive women. We further developed a mentoring programme and held regular tea sessions, dinners, and Q&A panels. Along with Daniela Bortoletto and the Women in Physics Society, we created the Conference for Undergraduate Women in Physics, held each year for female undergraduates to explore their options within science.
In my free time, I try to push myself to new physical and mental limits outdoors. I can usually be found rock climbing, trail running, or mountaineering. My favourite destinations include Tuolumne, Joshua Tree, North Wales, and Pembroke. Technical, runout slabs and crack climbing– I’m a trad junkie.
I’m obsessed with tiny puppies– properly incapable of maintaining composure. I hiccup a lot, especially when I’m nervous… it’s embarrassing. I sleep with my eyes open (weird right?) and have super-smelly nose powers. I’m also a DDR master and truly believe Zelda: Ocarina of Time was the best game ever. Word.
Training from the age of 6, I always wanted to be an artist. Physics was not part of the plan, but it was a natural fit. I didn’t grow up looking through a telescope, building robots, or conducting experiments at home. As an adult, I chose to be in physics because it provided me with a new, beautiful way to see the world and understand my place in it.
