Hi, I'm Briac, a PhD student at INRIA, Grenoble, France.  

I graduated from the Ensimag in 2021, a french engineering school in the field of informatics and applied mathematics. I'm currently studying computer vision, more specifically the topic of implicit surface reconstruction. My main interests lie in writing optimized GPU algorithms using OpenGL / CUDA and C++, though I also dip in Python occasionally. On this website, you will find videos showcasing some of my projects, as well as brief articles diving in topics surrounding surface reconstruction. You can contact me at firstname.lastname[at]inria.fr.
