I am a fifth year PhD candidate in the Department of Mathematics, advised by Professor Deanna Needell. I will graduate in June 2023, after which I will be working as a Quantitative Researcher at G-Research. I hold BA, MA, and MMath degrees from the University of Cambridge (Trinity College), and MA and CPhil degrees from UCLA. I'm British, and outside of math I'm a huge fan of fitness, the great outdoors, and the Los Angeles Dodgers.
Current Teaching
Spring 2023: Math 170E with Prof. Collins Odhiambo
All Teaching
I love teaching math and I strive to create an engaging, inclusive, and supportive classroom. You can see samples of my evaluations here and here.
I was honored to receive one of the inaugural Liggett Teaching Fellow awards in 2021.

Research Interests
Broadly, I am interested in the mathematics of data theory and machine learning. I have a strong background in probability theory and analysis, and enjoy finding applications of these in data science. Some topics I have researched include:
Variants of the randomized Kaczmarz method for corrupted, noisy linear systems.
Kaczmarz methods with random or streamed measurement data.
Gossip algorithms for the average consensus problem and their connection to the block randomized Kaczmarz method.
Topological data analysis for network converage problems.
Applications of the Kaczmarz method to rank agglomeration.
