Oscar Chinellato's research focuses on approximate solution methods for partial differential equations, iterative solvers for eigenvalue problems and linear systems of equations, numerical analysis and high performance computing. In particular this entails investigating resonator cavities by using high order (specialised) finite element models adapting, enhancing and developing eigenvalue solvers (and required components) for large sparse generalised (complex-symmetric) eigenvalue problems investigating on linear system solvers and preconditioners apt for shifted system matrices developing numerically accurate schemes for various purposes, e.g. (dense) matrix transformations, matrix factorisations, quadrature schemes generation, orthogonal polynomial applications, etc. reconstructing curves and surfaces from error afflicted measurement data with subsequent estimation of involved uncertainties parallelization of computationally intensive codes with MPI and OpenMP As a member of the Institute of Computational Science at ETH Zurich he is cooperating with the Computational Optoelectronics group of the Integrated Systems Laboratory, where numerical simulations of vertical cavity surface emitting lasers (VCSELs) are being developed. Moreover, he is involved in the extension of a simulation tool for accelerator cavities which are investigated by the Beam Dynamics Group of the Paul Scherrer Institute. Curriculum Vitae

Oscar Chinellato studied computer science at ETH in Zurich and did his diploma thesis (M.Sc.) in the Institute of Theoretical Computer Science. In his diploma project, he investigated several algorithms for the shortest vector problem and derived complexity bounds for a parametrised family of reduction based methods. Afterwards he went on to obtain a Ph.D. from the ETH in Zurich, where he was working as an assistant in Walter Gander's group. His advisor was Peter Arbenz and the focus of the thesis rested on the modelling and computing of resonance modes of lossy resonator cavities.
