We invite applications for a PhD studentship at the Department of Mathematics, University of Sussex. The research will focus on bifurcations in system behaviour and network structure for a class of dynamic network models.
This studentship is jointly funded by EPSRC and the School of Mathematical & Physical Sciences, University of Sussex.
The project in detail
Dynamic networks are ubiquitous in nature and arise as a result of the interaction and feedback between processes taking place ON the network and the dynamics OF the network itself. Both are inherently coupled where the topology of the network influences the dynamics on the network, while the state of the nodes and/or links can determine whether nodes and/or links are activated, deleted or whether links rewire. Characterising the global behaviour of such systems is via bifurcation analysis that can be carried out by direct numerical simulation of the full system or analytically using a system of ODEs that provide a good approximation to the stochastic process. The objective of the project is twofold. First, you will carry out a systematic study of the effectiveness of pairwise and effective-degree-type models in capturing the dual dynamics, and will determine their validity, depending on the type of dynamics on the network (i.e. epidemic and neuronal activity) and the dynamics of the network (e.g. random and link-type dependent link activation-deletion). In parallel, you will make the first steps in mapping the well-established concept of bifurcations from dynamical systems to bifurcations in network structure with the aim of providing a fuller global picture of the system and network behaviour.
The successful candidate will join the growing group of Mathematics Applied to Biology with considerable expertise ranging from Mathematical Epidemiology to Developmental Biology, and an active group of 3 DPhil students in Dr Kiss’s team working on closely related topics.
The project will be jointly supervised by Dr Istvan Z. Kiss (Principal supervisor, Mathematics) and Dr L. Berthouze (Co-supervisor, Informatics). Further collaborators include Dr PÃ©ter L. Simon from Institute of Mathemtics, EÃ¶tvÃ¶s LorÃ¡nd University Budapest, Hungary.
A Research Training Support Grant will be made available for additional training, visits to conferences etc.
Â£13,726 tax-free maintenance bursary plus fees waived for 3.5 years.
Due to funding only UK and EU residents are eligible.
UK residents are eligible for full awards, including fees and maintenance.
EU residents are eligible for awards covering fees only, but EU students who have studied in the UK for the previous three years may be eligible for a full award. For a precise statement of eligibility, please consult this EPSRC web page: http://www.epsrc.ac.uk/skills/students/help/Pages/eligibility.aspx
We are looking for a strong UK or EU Mathematics/Physics graduate with a first class degree or equivalent. You must have demonstrable experience in (1) mathematical modelling of biological processes (both deterministic and stochastic) and (2) programming (e.g. C/C++ or Matlab). Previous knowledge or exposure to network/graph theory or numerical computation/simulation with or on networks is desirable.
