- About Me
- 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.
