## About Me:

I am a second year PhD (third year MASDOC) student under the supervision of Professor Charlie Elliott and Björn Stinner. My office is B3.04 and if you wish to contact me, my email is P<dot>J<dot>Herbert@warwick.ac.uk. My interests lie in surface PDE and their applications, especially in biological applications alongside the respective numerical analysis and methods for solving the discrete equations. Another topic which interests me is non-uniqueness of solutions and how they may be interpreted.

I graduated in 2016 from Warwick with an MMath, I did my project under the supervision of Professor James Robinson discussing the stationary Navier-Stokes equations.

For my MASDOC MSc project I studied the shape of biomembranes with embedded proteins using a linearisation Cahnam-Helfrich energy for both the sphere and in the case of a plane, extending the work of A Variational Approach to Particles in Lipid Membranes using the tools of Small deformations of Helfrich energy minimising surfaces with applications to biomembranes.

My current research is around the topic of point particles embedded in these biological membranes along with a so called second order splitting method. Details of the second order splitting can be found in the paper of Elliott, Fritz and Hobbs Second order splitting for a class of fourth order equations. We are also studying the 'forcing' associated to the movement of embedded groups of point particles.
