Summary
🤩
Rockstar🎓
Top SchoolTuomas Kärnä is a software engineer and computational scientist with 11 years of experience, currently building high-performance solutions at Intel in Helsinki. He holds a PhD in Applied Mathematics from Université catholique de Louvain and an MSc in Information Technology from Aalto, blending rigorous numerical analysis with production-grade software engineering. His work spans HPC, distributed computing, CFD, machine learning and finite element methods, with a particular focus on heterogeneous computing and performance portability. As a notable open-source contributor to the Firedrake FEM project, he expanded mesh and function-space capabilities—adding cylinder and periodic mesh support and optimizing projection routines to boost solver efficiency. Comfortable moving between low-level performance tuning and higher-level algorithm design, he brings both research depth and practical delivery to complex simulation stacks.
