@collinsakosa
Machine learning and HPC research scientist focused on computational physics and materials.
I am a computational scientist with over 10 years' experience applying machine learning and high-performance computing to scientific and engineering problems.
My work combines Python-based ML, parallel computing (MPI/OpenMP), and GPU acceleration (CUDA, ROCm/HIP) to build predictive models and large-scale simulations for spintronics and magnetic materials.
I have led and published computational studies at institutions including Waseda University and RIKEN, and I mentor students in ML, HPC workflows, and scientific programming.
I seek to apply simulation-driven modeling, performance optimization, and data-driven approaches to accelerate research and translate computational insights into improved device design.
