Barrenechea gabriel.barrenechea@strath.ac.uk Date: July 26, 2026 Subject: PhD position at the University of Strathclyde, UK Dear colleagues, I have recently been awarded funding for a 3.5-year PhD studentship under my supervision (joint with Dr. Aurik Andreu, from the Advanced Forming Research Centre (AFRC), University of Strathclyde). The studentship is fully funded, and covers fees and stipend for a UK national (or an overseas student who is able to cover the difference in fees). The project is entitled "Adaptive finite element methods for induction heating", and it deals with the numerical approximation of a system of partial differential equations modelling temperature induced by a magnetic field. The project will contain both a strong numerical analysis component, as well as an industrial/ computational aspect. To apply, please send me (gabriel.barrenechea@strath.ac.uk) an up- to-date CV, and two reference letters. Ideally, the start date is 01/10/2026, but a later start date can also be negotiated. Informal enquires, and requests for further details can also be sent to me. The closing date is the 31/08, but if enough qualified candidates apply, we might close it earlier to allow the preferred start date. Thank you all in advance for distributing this to anyone you believe could be interested. Best, Gabriel ------------------------------------------------------- From: Ali R.
