Profile

I am an ML compiler compiler engineer at NVIDIA. I have been working with and contributing to the open-source MLIR compiler project since 2021. My research at university was concerned with code generation, domain-specific languages (DSLs), programming models and memory access optimizations for SIMD/GPU architectures. I am passionate about compilers, high-performance computing (especially GPUs), programming language design and parallel computing.
