Member: IEEE, IEEE Computer Society, IEEE Signal Processing Society

Computer Science PhD student in the Advanced Processor Technologies (APT) group at the University of Manchester specializing in High Performance Computing (HPC). My research is focused around compiler and runtime optimizations, and profiling for explicit parallel programs. List of my publications can be found on my Google Scholar profile and some of my contributions in the pepperpots organization on GitHub. I have previous industrial experience in vectorizing and parallelizing applications especially with focus on real time applications and signal processing. It includes writing modern C++ code with use of Advanced Vector Extension (AVX) intrinsics and CUDA.
