Summary
I received my Bachelors (Electrical Engineering) and Masters (Embedded Systems) from Eindhoven University of Technology. In April 2014, I successfully defended my PhD thesis at the same university. During the PhD I gained experience through two internships: with the OpenCL compiler group of ARM in Cambridge (UK), and with the cuFFT team of NVIDIA in Santa Clara (CA). After that, I worked as a GPU consultant at the SURFsara supercomputing centre and as a C++ performance engineer for a computer vision and machine learning team at Blippar. Currently, I work at TomTom on deep learning for autonomous driving.
Interests and expertise
My main expertise is C++11/14 and GPU programming (CUDA/OpenCL). On top of this, I also have experience with Python, compilers, high-performance computing, computer architecture, performance modelling, computer vision, and machine learning / deep learning.
My passion lies with the development of beautiful and performant C++11 codes, possibly accelerated by GPUs. Examples are CLTune, an OpenCL auto-tuner, and CLBlast, an OpenCL BLAS library.

NVIDIA Santa Clara (California)
CUDA software engineer
I worked for four months as an intern GPU programmer at the NVIDIA headquarters in Silicon Valley within the math libraries group, developing and performance tuning the CUDA Fast Fourier Transform library (cuFFT).
08/2012 - 12/2012
ARM Cambridge (United Kingdom)
Research intern
As part of a 4-month HiPEAC sponsored internship, I performed research within the ARM Mali OpenCL compiler team. I created a machine-code level mathematical performance model for the Mali T600-series, one of the first OpenCL capable low-power GPU architectures. Additionally, I worked on a GPU cache model, and was involved in the design of the PENCIL language, part of the CARP EU project.

Eindhoven University of Technology (Netherlands)
Doctor of Philosophy (PhD)
Under the supervision of prof. Henk Corporaal, I performed research on GPUs. This covered most aspects of GPUs, including micro-architecture, compilers, performance modelling, and programmability issues. This has led to two journal articles, a patent application, and several publications in international conferences and workshops. During my PhD, I interned for 4 months at both ARM and NVIDIA. My PhD thesis is titled 'Improving the Programmability of GPU Architectures' and is available in PDF form.
