About me

I'm a PhD student at the Royal Institute of Technology (KTH), Stockholm, Sweden, supervised by Prof. Patric Jensfelt and Prof. John Folkesson, working in the Computer Vision and Active Perception research group. My research interests include long-term mapping (typically weeks or months), object detection and machine learning. Prior to my PhD I worked on virtual/augmented reality and autonomous cars.

From June - November 2016 I am doing an internship at Robert Bosch North America working on the semantic segmentation of large point clouds.
