I study the solutions to equations and inequalities in whole numbers. These are called Diophantine problems and they’re part of number theory. I use “analytic” arguments which are often fairly elementary, which makes it analytic number theory.
I’ve become interested in something which seems very different: nonlinear dispersive partial differential equations (nonlinear dispersive PDEs). This is a type of mathematical model which describes physical systems from ocean waves to fibre optic cables.
For Warwick students these are the 4th year projects/Master's projects I can offer; I also offer URSS projects along similar lines.
