Career Summary
Biography
Bishnu Lamichhane works in applied and computational mathematics problems arising in science, technology and engineering. He applies computational mathematics to differential equations, data science, tomography and optimisation. He has a very strong track record of crossdisciplinary collaboration with academics from various disciplines including engineering, statistics, chemistry, physics and environment. These collaborations include research student supervision and grant submissions. He holds a Master of Science degree in Industrial Mathematics from the University of Kaiserslautern (Germany) and a PhD degree in applied mathematics from the University of Stuttgart (Germany)
The impact of Bishnu’s research is evidenced by his publications in numerous highranking journals, service to the Computational Mathematics Group (CMG) and the Australian Mathematical Science Institute (AMSI), invitations to review grants and participate in ARC and CRCP grant applications and PhD thesis examinations. He was elected to the Chair of the Computational Mathematics Group (CMG) in 2016 for two years and reelected again in 2018 for two years. He hosted Computational Mathematics and Computational Techniques (CTAC) conference in 2018 in Newcastle as the Conference Director. He was also an editor of an electronic supplement of the Australian and New Zealand Industrial and Applied Mathematics (ANZIAM) Journal. Moreover, he is elected to the Australian Mathematical Sciences Institute (AMSI) board in 2019 for two years.
Bishnu has a very strong crossdisciplinary collaboration record with local academics at the University of Newcastle. His current active collaborative projects with local academics at the University of Newcastle include:

Bishnu's collaboration with academics of the mathematics discipline at the University of Newcastle is also quite strong. With A/Prof M. Meylan and Prof N. Thamwattana, he applies computational techniques to problems arising from the modelling of propagation of waves in the marginal ice zone, neutron tomography, biological process, and dyesensitised solar cell. He supervises 7 students jointly with A/Prof Meylan and 4 students jointly with Prof Thamwattana. The widespread applicability of computational mathematics has facilitated him to work on a wide range of problems. That has resulted in many interdisciplinary collaborations.
Bishnu has also many collaborations outside the University of Newcastle. Inside Australia, his collaborators include academics from the Australian National University, the University of New South Wales, the University of Queensland, the University of Adelaide, the University of South Australia, and Monash University.

Brief History
After schooling in Gorkha, Nepal, Bishnu Lamichhane completed his Intermediate and Bachelor of Arts degrees from the Tribhuvan University, Nepal in 1991 and 1993, respectively. Tribhuvan University is the biggest government university in Nepal with many campuses spread throughout the whole country. He completed both degrees as a private student without attending any lectures. He was working as a fulltime school teacher during the study. A private student goes through the same assessment process in Nepal but they study themselves at home without getting help from lecturers. He secured the secondbest marks throughout the whole Tribhuvan University in the Bachelor of Arts exam and thus got the encouragement to study further. He then joined the Central Department of Mathematics of Tribhuvan University to complete a Master of Arts in mathematics in 1993. He completed the Master's degree in mathematics with a distinction grade securing the best marks in that discipline throughout the university and thus a gold medal.
Master and PhD in Germany
After completing the Master's degree in mathematics he worked as a casual teacher for two years at the Central Department of Mathematics during which time he got a permanent job as a section officer in the Nepalese Civil Service. After three years as a section office in Nepal, he got a DAAD (German Academic Exchange Programme) scholarship to study Master of Science in Industrial Mathematics from the University of Kaiserslautern, Germany. That was a turning point in his career. He completed the Master's degree from the University of Kaiserslautern with a 'Very Good" grade and joined the University of Stuttgart in Germany to complete his PhD in 2001. He completed his PhD in mathematics in 2006. Two main topics of his PhD research were mortar finite element methods with biorthogonal systems and nearly incompressible materials in elasticity.
Postdoctoral Experiences
He then joined Aston University in the UK for a postdoc position in signal processing. After one and half years at Aston University, he joined another postdoc position at the Australian National University (ANU), Canberra. He extended his research in finite element methods collaborating with academics at the ANU and the University of Hannover, Germany. He applied finite element methods for nearly incompressible elasticity, image processing problems, the approximation of thinplate splines and Stokes problems during the postdoc period at the ANU.
University of Newcastle
He joined the School of Mathematics and Physical Sciences at the University of Newcastle as a lecturer in November 2009. He was promoted to senior lecturer level in 2014.

The splines are defined as the minimiser of a penalised least squares functional. The penalties are based on partial differential operators, and are integrated using the finite element method. We compare three methods to two problems: to remove the mixture of Gaussian and impulsive noise from an image, and to recover a continuous function from a set of noisy observations.

We follow the CiarletRaviart formulation for the biharmonic problem to formulate our saddlepoint problem and the finite element method. The new formulation allows us to use the H 1 conforming Lagrange finite element spaces to approximate the solution. We prove a priori error estimates for our approach. Numerical results are presented for linear and quadratic finite element methods.

The boundary conditions at the front of the ice shelf, coupling it to the surrounding fluid, are written as a special nonlocal linear operator with forcing. This operator allows the computational domain to be restricted to the water cavity beneath the ice shelf. The ice shelf motion is expanded using the in vacuo elastic modes and the method of added mass and damping, commonly used in the hydroelasticity of ships, is employed. The ice shelf is assumed to be of constant thickness while the fluid domain is allowed to vary. The analysis is extended from the frequency domain to the time domain, and the resonant behaviour of the system is studied. It is shown that shelf submergence affects the resonant vibration frequency, whereas the corresponding mode shapes are insensitive to the submergence in constant depth. Further, the modes are shown to have a property of increasing node number with increasing frequency.

[more] An initialboundary value problem for a timefractional diffusion equation is discretized in space, using continuous piecewiselinear finite elements on a domain with a reentrant corner. Known error bounds for the case of a convex domain break down, because the associated Poisson equation is no longer regular. In particular, the method is no longer secondorder accurate if quasiuniform triangulations are used. We prove that a suitable local mesh refinement about the reentrant corner restores secondorder convergence. In this way, we generalize known results for the classical heat equation.

Here we consider a mixed finite element discretisation of the thin plate spline. By using mixed finite elements the formulation can be defined interms of relatively simple stencils, thus resulting in a system that is sparse and whose size only depends linearly on the number of finite element nodes. The mixed formulation is obtained by introducing the gradient of the corresponding function as an additional unknown. The novel approach taken in this paper is to work with a pair of bases for the gradient and the Lagrange multiplier forming a biorthogonal system thus ensuring that the scheme is numerically efficient, and the formulation is stable. Some numerical results are presented to demonstrate the performance of our approach. A preconditioned conjugate gradient method is an efficient solver for the arising linear system of equations.

These finite element methods are based on discrete Lagrange multiplier spaces from mortar finite element techniques. We prove optimal a priori error estimates for both methods. The first approach is based on a socalled standard Lagrange multiplier space for the mortar finite element method, where the Lagrange multiplier basis functions are continuous. The second approach is based on a socalled dual Lagrange multiplier space, where the Lagrange multiplier basis functions are discontinuous. The advantage of using the second approach is that easy static condensation of degrees of freedom corresponding to the Lagrange multiplier is possibly leading to a symmetric positive definite formulation. © 2013 IMACS.

The threefield formulation is based on three unknowns: displacement, stress and strain. In order to obtain an efficient discretization scheme, we use a pair of finite element bases forming a biorthogonal system for the strain and stress. The biorthogonality relation allows us to statically condense out the strain and stress from the saddlepoint system leading to a symmetric and positivedefinite system. The strain and stress can be recovered in a postprocessing step simply by inverting a diagonal matrix. Moreover, we show a uniform convergence of the finite element approximation in the incompressible limit. Numerical experiments are presented to support the theoretical results. © 2013 Elsevier B.V.

We show the optimal and robust convergence of the displacementbased discrete formulation in the nearly incompressible case with the choice of approximations based on quadrilateral and hexahedral elements. These choices include bases that are well known, as well as newly constructed bases. Starting from a suitable threefield problem, we extend our adependent threefield formulation to geometrically nonlinear elasticity with SaintVenant Kirchhoff law. Additionally, an adependent threefield formulation for a general hyperelastic material model is proposed. A range of numerical examples using different material laws for small and large strain elasticity is presented. © 2007 Elsevier B.V. All rights reserved.

A key mechanism for cell aggregations and sorting is that of cellcell adhesion, a process by which cells bind or stick to each other through transmembrane proteins. This process is able to achieve cell sorting via the differential adhesion hypothesis (DAH) (Steinberg (1962b,a,c)). Armstrong et al. (2006) proposed a nonlocal advection model that was able to simulate the DAH. In their study, cells were modelled using a conservative system acting on cell density. The equations allowed for only two types of movement, random diffusive and directed adhesive movement with the adhesive movement taking into account cells within a finite sensing radius. Using the model with differing cell adhesion values they were able to simulate engulfment, partial engulfment, mixing, and sorting patterns between two cell types in both one and two dimensions. The aggregation of cells can be considered as a type of swarming, in that it is the collective behaviour of a large number of self propelled entities (Loan and Evans (1999)). Examples of macroscopic biological swarms include locust swarms, ungulate herds, fish schools, bird flocks, etc. Nonlocal swarming models have been used to successfully model these phenomena (see Bernoff and Topaz (2013)). Based on the principle of conservation of mass, a fixed population density moves at a velocity that arises as a result of social interactions (Mogilner and EdelsteinKeshet (1999)), giving rise to an equation of the form t + r(r(Q(x)) = 0; with Q(x) being a social potential function used to describe the social interactions between individuals. In this paper we look at the Armstrong et al. (2006) model of cellcell adhesion and recreate it by extending the swarm modelling techniques to equations of the form t + r(r(Q(x)f = 0: In doing so we find that by modelling in this way we are able to capture the same qualitative behaviour as the original model with a vastly reduced computational cost. We also derive a numerical scheme to simulate the model in one dimension in such a way that it can be easily adapted to other swarm problems. We find that the convergence rate of the numerical scheme is greater than 1.7 in all of the scenarios presented.

Improved blending models through optimisation of coke microstructure$279,620
This funding is to study "Improved Coal Blending Models Through Optimisation of Coke Microstructure”.
Accurate prediction of coke quality for coal blends is critical to technical marketing capability to provide sound advice to marketers and customers in relation to potential coal blends. Current predictive models are limited by a largely empirical approach to blending, based on relating measured coke properties to input coal properties. The project is established to provide a PhD scholarship.
