Career Summary
Biography
James McCoy completed his PhD in pure mathematics in 2002 under the supervision of Klaus Ecker at Monash University. The title of his thesis was "The surface area preserving mean curvature flow". After completing post doctoral positions at the Australian National University with Ben Andrews and Neil Trudinger, in 2005 James took up an ARC Postdoctoral Fellowship as part of a joint ARC grant with Ben Andrews. In July that year he moved to the University of Wollongong, combining a lecturing position with his ARC research grant. In January 2018 he moved to the University of Newcastle; in July 2018 he became Head of Mathematics Discipline at Newcastle.
James is a 'geometric analyst' whose main research interests are questions related to curvature driven heattype flows of hypersurfaces. Such questions include long time existence of globally constrained curvature flows, formation of singularities (where the curvature becomes unbounded) in curvature flows and extension of classical flow solutions beyond singularities using a 'surgery' procedure. Such analysis relies heavily on techniques from differential geometry, partial differential equations (second and higher even order elliptic and parabolic equations) and topology.
James has refereed articles for over 30 international journals, see his record at publons.com
James has reviewed over 140 articles for Math Reviews of the American Mathematical Society, see ams.org/mathscinet and search for "McCoy, James" under "Reviewer".
James is an Associate Editor of the Journal of the Australian Mathematical Society.

This reduces to studying the curve diffusion flow for the profile curve of the ribbon.We provide: (1) a complete classification of stationary solutions; (2) qualitative results on shrinkers, translators, and rotators; and (3) an explicit parametrisation of a shrinking figure eight curve.

We use classical calculus of variations and consider mathematical energies dependent on the curvature and torsion of the protein backbone curve. We demonstrate classes of mathematical energies for which a given helix, or all helices, are extremisers. A future goal is to find within these energies some which permit less regular protein backbone curves, as also observed in nature. As a step in this direction we incorporate a new function into the model, dependent on position along the backbone curve, which permits some allowance for variability in structure due to different amino acid components, side chains, or obstacles. © 2011 by Nova Science Publishers, Inc.

[more] We consider the parabolic polyharmonic diffusion and the L2{L^{2}}gradient flow for the square integral of the mth arclength derivative of curvature for regular closed curves evolving with generalised Neumann boundary conditions. In the polyharmonic case, we prove that if the curvature of the initial curve is small in L2, then the evolving curve converges exponentially in the C8 topology to a straight horizontal line segment. The same behaviour is shown for the L2gradient flow provided the energy of the initial curve is sufficiently small. In each case the smallness conditions depend only on m.

[more] ABSTRACT: We consider the motion of convex surfaces with normal speed given by arbitrary strictly monotone, homogeneous degree one functions of the principal curvatures (with no further smoothness assumptions). We prove that such processes deform arbitrary uniformly convex initial surfaces to points in finite time, with spherical limiting shape. This result was known previously only for smooth speeds. The crucial new ingredient in the argument, used to prove convergence of the rescaled surfaces to a sphere without requiring smoothness of the speed, is a surprising hidden divergence form structure in the evolution of certain curvature quantities.

[more] In this paper we study the steepest descent L2gradient flow of the functional W¿1,¿2 , which is the the sum of the Willmore energy, ¿1weighted surface area, and ¿2weighted enclosed volume, for surfaces immersed in R3. This coincides with the Helfrich functional with zero 'spontaneous curvature'. Our first results are a concentrationcompactness alternative and interior estimates for the flow. For initial data with small energy, we prove preservation of embeddedness, and by directly estimating the EulerLagrange operator from below in L2 we obtain that the maximal time of existence is finite. Combining this result with the analysis of a suitable blowup allows us to show that for such initial data the flow contracts to a round point in finite time.

[more] Inspired by earlier results on the quasilinear mean curvature flow, and recent investigations of fully nonlinear curvature flow of closed hypersurfaces which are not convex, we consider contraction of axially symmetric hypersurfaces by convex, degreeone homogeneous fully nonlinear functions of curvature. With a natural class of Neumann boundary conditions, we show that evolving hypersurfaces exist for a finite maximal time. The maximal time is characterised by a curvature singularity at either boundary. Some results continue to hold in the cases of mixed Neumann¿Dirichlet boundary conditions and more general curvaturedependent speeds.

This coincides with the Helfrich functional with zero 'spontaneous curvature'. Our main result is a complete classification of all smooth immersed critical points of the functional with ¿1=0 and small L2 norm of tracefree curvature, with no assumption on the growth of the curvature in L2 at infinity. This not only improves the gap lemma due to Kuwert and Schätzle for Willmore surfaces immersed in R3 but also implies the nonexistence of critical points of the functional satisfying the energy condition for which the surface area and enclosed volume are positively weighted. © 2013 SpringerVerlag Berlin Heidelberg.

Fire front modelling using curvature flow 2013  2015
In this project we modelled fire line merging using flow of planar curves by their curvature, a suitable model for uniform fuel over flat terrain (eg grass fires). We also introduced an evolving surface model that could take into account height dependence from varying topography and fuel properties.

Higher order elliptic and parabolic geometric partial differential equations 2007 
This is a longterm ongoing project covering one of my main research areas: geometricallyinspired higher even order elliptic and parabolic partial differential equations, many eminating from geometric problems in the calculus of variations. I have supervised PhD students in this field and postdoctoral fellows who have gone on to be successful academic mathematicians in their own rights or found lucrative positions working in industry.
We have considered various scenarios of static (elliptic) and evolving (parabolic) curves, surfaces and hypersurfaces, with or without boundaries. Much ongoing work and collaborations continue.
Applications of this work include improving understanding of the Helfrich model for biomembranes such as the red blood cell.

I have worked on second order fully nonlinear curvature flow and associated elliptic problems since I was a PhD student. I continue to work in this area. I have supervised PhD students in this field.
I have worked in particular on globally constrained curvature flows and unconstrained contraction flows. I have considered with collaborators nonsmooth speeds and characterised singular behaviour.

Fully nonlinear curvature flow of axially symmetric hypersurfaces 
Shape of the red blood cell 2013 
The shape of the red blood cell is a minimiser of the curvaturedependent Helfrich energy functional which includes several parameters that can permit different minimising shapes. In particular, certain parameter combinations can lead to spherical blood cells instead of the normal biconcave shape; such cells lead to the blood condition named spherocytocis.
Minimisers of the Helfrich functional satisfy a fourthorder Euler Lagrange elliptic partial differential equation that in view of its high order is relatively difficult to analyse. In the early stage of this project, collaborators and I uncovered combinations of the parameters that could lead to spherical minimisers. In the next multidisciplinary stage I will work with colleges in the college of Health, Medicine and Wellbeing to establish relationships between drugs, diet and other environmental features and the parameters in the model. This should lead to greater understanding of the model and the associated blood condition. Knowledge uncovered could be relevant to other conditions including diabetes.
