PhD Mathematical Physicist | Specialist in Fluid Dynamics, Applied Math & Scientific Writing

Profile Summary

I am completing a PhD in Mathematical Physics at a top UK university, where my work spans variational and Lagrangian methods applied to relativistic fluid dynamics, classical fluid dynamics, complex systems, and related areas. My postgraduate research also includes a paper on quantum–classical correspondence, giving me a solid foundation in quantum mechanics, relativity and semiclassical analysis. I have authored five peer-reviewed publications in international journals. Supported by several years of advanced research experience, I have developed and applied models to solve complex problems in physics and engineering, bridging theory with practical applications. In addition to my academic research, I have completed consulting projects in quantum chaos, quantum computing concepts, quantum filtration models, and theoretical topics at the interface of general relativity and quantum mechanics, providing mathematical formulations, conceptual clarity, and high-level technical documentation. I specialise in: Mathematical modelling & analytical/variational methods Quantum–classical correspondence & semiclassical methods Quantum systems, quantum chaos & quantum computing concepts Numerical computation & simulation Fluid dynamics, multiphase flows & complex systems (including simulations and numerical methods) Scientific writing, literature reviews & academic editing to publication standard I bring a consistent record of 5-star client feedback for clarity, rigour, and reliability. My goal is to deliver scientifically rigorous, mathematically sound, and clearly communicated work tailored to the needs of each project.
