About
Dr. Daniel Ratliff is an applied mathematician at Northumbria University since 2020, specializing in nonlinear waves across physics. He holds a PhD in Mathematical Physics from the University of Surrey (2017), focusing on conservation laws and universal nonlinear equations. His research explores fluid dynamics, magnetospheric plasmas, and soft matter physics, with notable work on water wave instabilities and Whistler-mode chorus waves. Key contributions include deriving reduced nonlinear models for wave evolution and investigating wave-particle interactions in space plasmas. He actively advocates for LGBTQ+ inclusion in mathematics through initiatives like the QED Network and organized events such as the 2025 Queer Experience in Mathematics workshop. His work bridges theoretical analysis, numerical simulations, and interdisciplinary applications, including data sonification of space phenomena. Supervising PhD student Adam Toulson, Ratliff's research also involves collaborations on quasicrystal formation and space weather dynamics.
