Hi, I am Alberto Paganini and I am Departmental Lecturer in Numerical Analysis at the University of Oxford.
I have studied mathematics at ETHZ and have obtained a PhD under the supervision of Prof. Dr. R Hiptmair and Prof. Dr. Ch. Hafner.
The title of my thesis reads: Numerical shape optimization with finite elements. In short, I have studied approximation of so-called shape gradients and have developed a shape optimization algorithm in the framework of finite element discretization of state constraints. Finally, I have applied these results to the optimization of optical microlenses.
The 1. of August 2016 I moved to Oxford to work as a Postdoctoral Research Assistant with Prof. Dr. Patrick Farrell.
The 1. of August 2017 I became a Departmental Lecturer in Numerical Analysis.
