Pontus Johannisson is Senior Scientist at RISE in Göteborg. He received his Ph.D. degree in 2006 from Chalmers University of Technology, Göteborg with his thesis "Nonlinear Intrachannel Distortion in High-Speed Optical Transmission Systems". This work was mainly focused on electromagnetic modeling of fields propagating in optical communication fibers, with the aim of describing and counteracting nonlinear signal distortion. He has published about 100 journal and conference papers and was appointed Associate Professor (docent) in February 2014.
In 2006, he joined IMEGO (later renamed to "Acreo" and "RISE") in Göteborg, where he mainly worked with inertial navigation using MEMS-based accelerometers and gyroscopes. His typical responsibilities included calibration of inertial measurement units and navigation within various motion tracking projects.
In 2009, he joined the Photonics Laboratory at Chalmers University of Technology, first as Postdoctoral Researcher and later as Assistant Professor. Johannisson worked on cross-disciplinary projects involving the Departments of Microtechnology and Nanoscience, Signals and Systems, and Computer Science and Engineering, all within the Fiber Optic Communications Research Center (FORCE). The work spanned over a range of topics including optimal estimation, real-time digital signal processing, communication theory, information theory, electromagnetic modeling, and digital ASIC development.
Johannisson joined Acreo Sensor Systems (currently "RISE Sensor Systems") in Göteborg in 2016, where he works with sensor and system development within a wide range of topics, including (but not limited to) energy harvesting, hydroacoustic communication, low-coherence interferometry, vehicle-to-everything (V2X) technology, and vibration monitoring.
