Job description

The Department of Mathematics at the University of Sussex offers a fixed term three years (36 months) post doctoral position in Analysis of Partial Differential Equations (PDEs).

The post has become available through the award of an EPSRC grant to Dr Ali Taheri for the project “Topology of Sobolev spaces and quasiconvextiy: multiplicity and singularity analysis for extremals and local minimizers”.

The aim of the project is to extend and deepen our understanding of quasiconvexity and to discover and exploit further its close links to PDEs, geometry and topology as well as some of its intimate and key applications in mechanics, nonlinear elasticity, and material sciences.

On a more mathematically rigorous front the prime objective of this research is to develop new tools and cutting-edge techniques for establishing sharp and optimal regularity results, to devise fine singularity analysis for various classes of extremals and local minimizers of quasiconvex variational integrals and to obtain a clearer picture of the energy landscape on the relevant function spaces.

We welcome applications from all candidates in related areas broadly interpreted but candidates with major interest in Mathematical Analysis, Calculus of Variations, PDEs, Geometric Analysis and Geometric Function Theory are particularly welcome.

The post-holder will work closely with the principal investigator Dr Ali Taheri in the Analysis and PDEs research group. The post comes with a generous travel bursary that will enable the successful candidate to participate in international conferences and summer schools.

Prospective candidates should hold a PhD in Mathematics, Theoretical Physics or a closely related subject and have experience in publishing papers and conducting research of highest quality.  

Candidates should include in their application the following:

  • Academic CV
  • Official academic transcripts
  • Contact details for three suitable referees
  •  A personal statement (55 words maximum) outlining their suitability for the position and research experience to date relevant to the project
  • Application form

 All enquiries should be directed to Dr Ali Taheri,

The University is committed to equality and valuing diversity, and applications are particularly welcomed from women and black and minority ethnic candidates, who are under-represented in academic posts in Science, Technology, Engineering, Medicine and Mathematics (STEMM) at Sussex.

 Please note that this position may be subject to ATAS clearance if you require visa sponsorship.

The University of Sussex values the diversity of its staff and students and we welcome applicants from all backgrounds.
