I work on generative and differentiable rendering for autonomous driving — novel view synthesis, scene generation, and sensor-realistic simulation.

About

I am a second-year industrial PhD student at Zenseact and Chalmers University of Technology, working with Fredrik Kahl and the Computer Vision group, funded by WASP. My research is on machine learning for autonomous driving — predominantly generative and differentiable rendering methods.

Before the PhD I was a hybrid system software engineer at Koenigsegg, and during my Master's I founded and led the autonomous systems group for Chalmers Formula Student's driverless racing project. I hold an MSc in Systems, Control and Mechatronics from Chalmers and a BSc in Electrical and Computer Engineering from Técnico, University of Lisbon.
