<section class="prose dark:prose-invert w-full"><p>I’m a senior research engineer with a passion for high-performance computing (HPC), parallel programming, 3D graphics, and visualization. I have a background both in research and software engineering. Before joining HPE and coming back to the HPC world, I worked on a 3D visualization project as part of a leading infotainment system used in Audi and Porsche cars.</p>
<p>In the course of my research path, I completed a postdoctoral appointment at the Center for Applied Scientific Computing (CASC) in Lawrence Livermore National Laboratory (LLNL) where I was part of the Exascale Computing Project (ECP/Alpine). My work there focused on portability and parallelism challenges that arise in in situ data analysis and visualization of HPC applications. I received my PhD in 2018 from the Technical University of Darmstadt, Germany, where I focused on performance tooling and modeling techniques to identify scalability and parallelism bottlenecks. I published more than 12 peer-reviewed papers and served as a committee member on numerous occasions.</p>
<p>You will find my up to date CV on LinkedIn. The publications section on this website is a work in progress aimed to present a detail overview of articles and projects I worked on.</p>
<p>My technical skills include modern C++, C, Python, CUDA, GLSL shaders, CMake, Docker. On occasion, I use Jupyter Notebooks for fast prototyping. I actively explore new areas and recently I’ve been experimenting with devcontainers and web development.</p>
