I am a PhD student at the Department of Electrical Engineering at Linköping University (LiU) in Sweden. I am supervised by Kailai Li and Fredrik Gustafsson. My research interests focus on reliable state estimation using multi-sensor fusion for mobile robotics. I am a member of the Agile Sensing and Intelligence Group (ASIG). I am also the major executor of the project CASIIS.
