Gianmarco Mengaldo
Research Associate

Gianmarco Mengaldo obtained his BSc and MSc in Aerospace Engineering at Politecnico di Milano. He did his final year project at MOX (part of the Department of Mathematics at Politecnico di Milano) on “Nonlinear Fluid-Structure Interaction with application in Haemodynamics” with Prof. Luca Formaggia and Dr. Fabio Nobile. After his graduation he worked for three months in the CMCS group headed by Prof. Alfio Quarteroni at EPFL (Ecole Polytechnique Federale de Lausanne). He was also student team leader of the propulsion group for the ESA mission ESMO (European Student Moon Orbiter).

In 2011 Gianmarco Mengaldo joined the Department of Aeronautics at Imperial College London where he carried out his PhD under the supervision of Prof. Spencer Sherwin and Dr. Tamer Zaki. While at Imperial College he was part of the  LFC-UK group funded by EPSRC, Airbus and EADS-IW and based in the Department of Mathematics. After the PhD he was appointed as a Research Associate at Imperial College within Prof. Sherwin’s research group. He is currently at ECMWF as a numerical scientist and continue actively his collaboration with SherwinLab.

His main interests involve numerical analysis and numerical methods to solve PDEs, with a particular expertise in spectral element methods. Applications involve compressible boundary-layer instability and transition, turbulence, biomedical flows, geophysical flows and more recently finance.
