I am a fourth-year PhD student on the MathsCDT. I am interested in nonlinear acoustics in curved waveguides with zero mean flow; this has an application to musical instruments. My supervisor is Dr Ed Brambley.

Education:

Before coming to Warwick I obtained a BA (Mathematics, 2017-2020) + MSci (Astrophysics, 2020-2021) at the University of Cambridge. My master's project investigated the effects of black-hole binaries on counter-rotating accretion discs.

Talks:

On my PhD topic, "Nonlinear Acoustics in a general 3D duct", I have delivered

• talks at BAMC 2023 (Bristol, 04/23) and 2024 (Newcastle, 04/24),
• a talk at Warwick Mathematics' SPAAM Seminar (11/23),
• a talk at ICSV30 (Amsterdam, 07/24),
• a talk at ICTAM2024 (Daegu, 08/24).

Publications

• "Multimodal nonlinear acoustics in two- and three-dimensional curved ducts"
