Michail Diamantakis joined the ECMWF research department in July 2011 as a senior scientist. Since 2016 he leads the Numerical Methods  team of the Earth System Modelling section. His educational background is in Mathematics, Numerical Analysis and Scientific Computing and he has long working experience in Numerical Weather Prediction.

Professional interests: 
  • Numerical methods for atmospheric dynamics and non-linear diffusion solvers
  • Semi-Lagrangian atmospheric transport and mass conservation
  • Dynamical core development
  • Computational Fluid Dynamics
  • Scientific & High Performance Computing
  • Time-stepping schemes for differential equations
Career background: 

Michail Diamantakis received his undergraduate degree in Mathematics from the University of Ioannina, Greece in 1990, an M.Sc. in Computing Science (1991) and a PhD in Numerical Analysis (1995) both from Imperial College London. Between 1997-1999 he worked as a Research Associate in the Centre for Process Systems Engineering at Imperial College developing industrial solvers for large sparse mixed systems of differential-algebraic equations. His work was incorporated in the state-of-the-art process modelling software gPROMS used by many leading chemical, pharma, food, and energy companies for process design and simulation. He joined the UK Met Office as a research scientist in 1999. After completing the graduate training programme in Meteorology he worked in NWP and climate modelling focusing in the development, maintenance and validation of the "New Dynamics" and "ENDGame" semi-Lagrangian semi-implicit dynamical cores, research in numerical methods for atmospheric modelling and the coupling of dynamics with physics. Between 2008-2011 he worked in the private sector in London, initially as a senior weather CAT risk modeller and later on as a senior computational fluid dynamics software engineer. He joined the research department at ECMWF in 2011 as a senior scientist and in 2016 he became the team leader of the Numerical Methods group. His current area of work includes, development and maintenance of the ECMWF model spectral semi-implicit semi-Lagrangian dynamical core,  transport equation schemes, improving scalability of numerical methods, aspects of tangent-linear models related to the dynamical core and research in numerical techniques for atmospheric modelling in general.
