Job Title: Research Associate in Nonlinear Waves in Stratified FluidsJob Reference: REQ260041Date Posted: Wed, 21 Jan 2026 00:00:00 GMTApplication Closing Date: Sun, 15 Feb 2026 00:00:00 GMTLocation: LoughboroughPackage: Specialist and Supporting Academic Research grade 6 from £35608This position is Full Time, Fixed Term (30 Months)Loughborough University invites applications for a Postdoctoral Research Associate position in Nonlinear Waves, for a duration of two and half years. The successful candidate will join the Department of Mathematical Sciences to work with Dr. Ricardo Barros on the research project "Internal Solitary Waves of Mode-2: Theory, Models and Experiments", funded by the Leverhulme Trust. The position includes a generous allowance for travel, training, and dissemination activities. The project spans the interface between experimental fluid dynamics and applied mathematics and will make significant contributions to both areas. Its goal is to develop a comprehensive mathematical and physical description of mode-2 internal solitary waves (ISWs), thereby enhancing our understanding of these phenomena in the oceans and other stably stratified fluids. For the first time, the research will provide an integrated mathematical, computational, and experimental study of mode-2 ISWs, building on recent results from the research team, who were the first to discover solutions of the governing fluid dynamic equations describing these waves and to generate them in the laboratory under realistic oceanic density profiles. The project will employ a range of techniques, including mathematical modelling, asymptotic analysis, numerical analysis, and scientific computing, and will involve collaboration with colleagues at Newcastle University, the University of Bath, Penn State University (USA), and the New Jersey Institute of Technology (USA). We are looking for candidates with a strong research background in applied mathematics, fluid dynamics, nonlinear waves, or closely related areas. Applicants should have expertise in numerical methods for dispersive nonlinear partial differential equations. Familiarity with numerical solutions for the fully nonlinear Euler equations for homogeneous or stratified fluids would be advantageous, although not essential. For informal enquiries please contact Dr. Ricardo Barros R.Barros@lboro.ac.uk. For more information refer to the Job Description and Person Specification.
