Bio

Fancy meeting you here

I'm Jessica — 25 years old, excessive reader, lover of games (both of the video and board nature), and aspiring renaissance woman. Professionally, I am a 4th year Ph.D. student at University College London, based at the Mullard Space Science Laboratory. I'm a cosmologist working towards answering the burning questions we have about dark matter. I do this by focusing on weak gravitational lensing, and I develop machine learning methods for solving the inverse problem of mass-mapping. I work with high-dimensional astrophysical data, and I've honed expertise in Python, PyTorch, JAX, Bayesian uncertainty quantification, and regularised generative modelling.

Pure maths, statistics, and coding are my passions. Post-Ph.D. I'm aiming to transition into quantitative research, where I can combine my love of mathematics with my experience in machine learning.

I love hearing from people, so if you're interested in what I do, have any questions, or would like to collaborate, please do get in touch! The button on the top right has my contact details.

Beyond the Lab

Outside of my academic life, I enjoy pursuing an ever-increasing number of hobbies. I'm a long-time musician playing the harp and violin and currently perform with the Woking Symphony Orchestra. (Fun fact: I was going to pursue music professionally before I chose to study theoretical physics!) Other established hobbies include reading (fantasy, SF, translated literature etc.), bouldering, and the aerial arts.

A book I've been loving recently

The Way of Kings book cover

Title: The Way of Kings

Author: Brandon Sanderson

If you read high fantasy you've likely already heard of this book. 1,100 pages long and it couldn't be long enough! Sanderson is the king of rule-bound magic systems and intricate world-building. It's impossible not to get lost in the worlds he creates.
