I have several interesting Part B and C dissertation projects that touch upon many areas in applied mathematics, and include a mixture of theory and computation. If you're a student looking for interesting projects, please feel free to send me an email and let me know of your interests.
A late congratulations to second-year student Tom Chandler (Lincoln College, Oxford) for successfully presenting his poster Jet flows from angled nozzles at the British Applied Mathematics Colloquium 2016 that took place last month in Oxford. Tom's work studies the situation of fluid ejected from an angled nozzle and driven by gravitational forces. It turns out that there are some rather non-trivial issues concerning the angle that a liquid separates from a solid, and this deals with the interplay between geometry, surface tension, and gravity. Tom's poster forms part of his third year dissertation project and will continue to a summer research project at the Mathematical Institute.
I'm happy to announce the publication of my paper in the journal Nonlinearity with Michael J. Ward (University of British Columbia) on localized spot patterns on the surface of the sphere. In this paper, we develop the detailed asymptotics that describe the slow dynamics of spot patterns modelled by a system of reaction-diffusion equations. The interesting twist is that when the patterns occur on a surface of non-zero curvature, the methodology must account for higher-order terms due to the changing geometry. It is a wonderful paper with some beautiful mathematics and beautiful pictures.
I'll be attending the Fluid and Elasticity 2015 conference, from June 22-24 in Biarritz, France, and presenting some joint work with Stephen K. Wilson (Strathclyde University) and Howard A. Stone (Princeton University).
I'm happy to announce the publication of two new papers. The first paper is published in Nonlinearity and is on the topic of developing exponential asymptotics for problems with coalescing singularities (motivated by the study of ship waves, above left) with Jonathan Chapman (Oxford). The second paper, published in the Journal of Fluid Mechanics, and collaboration with Weiqing Ren (National University of Singapore) and Weinan E (Princeton) seeks to explain the importance of distinguished limits in the classical contact line problem. Both papers can be downloaded from the research section.
