Cyrille Bonamy

EXPERT IN SCIENTIFIC COMPUTING### AN EXCITING AND VARIED JOB I am an expert in scientific computing at the [LEGI](https://www.legi.grenoble-inp.fr/) laboratory after a thesis in fluid mechanics at the [PPRIME](https://www.pprime.fr/) institute and a first permanent position as a research engineer at [the University of Lille](https://www.univ-lille.fr/) as head of the [computing division of the IT System Department](https://hpc.univ-lille.fr/). In the LEGI laboratory, my activity is mainly "research", and concerns two main themes: sediment transport, and rotating machinery. I co-supervise several theses since 2016 (four theses defended, three in progress), I am the referent for the development and data analysis thema. I also use my skills in computer science to disseminate and enhance our codes and data and I participate in the transfer of knowledge either through oral communications, scientific articles or through vacations at the engineering school [ENSE3-GINP](https://ense3.grenoble-inp.fr/). A common feature of these activities is the use and development of the opensource toolkit [OpenFOAM](https://openfoam.com/). In particular, I am the maintainer and software manager of the [sedFoam](https://bonamyc.gricad-pages.univ-grenoble-alpes.fr/pages_perso/sedfoam.html) solver, which will soon be integrated into the official OpenFoam distribution. More generally, I encourage and support the use and development of this tool, both within the laboratory and outside. In particular, I am a member of the [Foam-U](https://foam-u.fr/) Board of Directors, and main animator of the regional network of OpenFOAM users. I am the referent of the laboratory for all that concerns the development, the use and the optimisation of high performance computing codes (proprietary, community or in-house). I guide and support users according to their needs towards the appropriate solutions in terms of infrastructure : local (laboratory cluster), regional ([GRICAD](https://gricad.univ-grenoble-alpes.fr/)), national ([GENCI](https://www.genci.fr/)), computing grids ([EGI](https://www.egi.eu/), [Grid5000](https://www.grid5000.fr/)), bigdata environements (Storm). Finally, I encourage, train and sensitise PhD students, engineers and researchers to use Python for experimental data processing and for pre and post processing of numerical data. In addition, I am very interested in environmental issues; in the past, I have instilled a dynamic around environmental aspects in the IT department of the [University of Lille](https://www.univ-lille.fr/) (setting up a cold corridor, encouraging mutualisation and rationalisation, etc.). Since my arrival at the LEGI laboratory, I have been an active member of the CNRS [EcoInfo](https://ecoinfo.cnrs.fr/) Service Group (GDS) and I am particularly interested in the ecodesign of digital services (software consumption in the usage phase, Life Cycle Analysis of a digital service...).
