There she worked on various simulations in the field of pharmaceutical engineering and collaborated closely with industry. Together with her team she developed a GPU based discrete element method (DEM) software used for simulating granular matter. This software was also coupled with a commercial computational fluid dynamics (CFD) solver to enable the simulation of multiple phases interacting.

Personal Statement of Interest: Due to my current position, I closely followed the activities of AHUG during the past two years. I think the organization and the sense of community it has created is very helpful. It enables exchange and collaborations, which otherwise would be much harder to achieve without AHUG. Serving as a board member would allow me to get more involved, get to know different researchers and connect them, and help advancing the Arm HPC ecosystem.

Filipo Spiga, NVIDIA

Filippo is member of the NVIDIA EMEA HPC team working as HPC Developer Relations manager for Arm CPU and GPU. His GPU journey and appreciation for Fortran started back in 2009, at the time of the first GPU Tesla architecture during the early years of CUDA. He is also involved in growing and nurturing a healthy HW and SW ecosystem of GPU-accelerated Arm-based systems, including NVIDIA Grace Superchip. Prior NVIDIA, Filippo was Staff Research Engineer at Arm Research in the Software and Large-Scale System team. Before Arm, he worked for 5 years at the Research Computing Services of University of Cambridge as Head of Research Software Engineering leading several HPC projects both with academia and private companies.
