Research

I work in the domain of machine learning and neuromorphic engineering at EISLAB since 2010, with a special interest for embedded intelligence and information processing principles motivated by results in neuroscience. I currently work on projects related to neuromorphic systems and machine learning for:

• Condition monitoring.
• Sub-milliwatt spatiotemporal pattern recognition for IoT.
• Automation of heavy construction equipment.
• System interoperability in IIoT and Industry 4.0.
• Automation of edge datacenters.
• High-quality steel manufacturing.

I studied in the Swedish Graduate School of Space Technology and have a PhD in Physics (2002-07) and I did a postdoc at IFPA in Belgium (2008-09), both focusing on numerical simulations and modelling in theoretical physics (finite temperature and density field theory, mean field models, general relativity in compact objects). I did the MSc diploma work in ATLAS at CERN (2001). My curiosity for brains and neuromorphic engineering made me shift research focus. I did a second postdoc in brain-inspired machine learning (2010-11) at EISLAB, where I presently work and are involved in the AI Innovation Hub and the SKF-LTU University Technology Center.

Teaching

I am the examiner of the following courses:

• Electric circuit theory (E0003E), link.
• Neural networks and learning machines (D7046E), link.
• Introduction to programming for engineers (D0017E), link.

Since 2014, I coordinate the Engineering Physics and Electrical Engineering program at LTU (Civilingenjör, 300 credits). Before 2010 I taught several courses in physics.
