Research

Machine learning and neuromorphic computing. See my scholar profile for references.

I have a PhD in Physics (2007, Swedish Graduate School of Space Technology) and I did a postdoc at IFPA in Belgium (2008-09), both focusing on numerical simulations and modelling in theoretical physics. I did the MSc diploma work in ATLAS at CERN (2001). My curiosity for brains, neuromorphic engineering and the physics of consciousness 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 e.g. the AI Innovation Hub.

NCE focus issue: applications of neuromorphic engineering to wireless networks for distributed sensing.

Teaching

I am the examiner of the following courses:

• Neural Networks and Learning Machines (D7046E), link.
• Neuromorphic Computing, upcoming course in the Applied AI program.

Since 2014, I coordinate the Engineering Physics and Electrical Engineering program at LTU (Civilingenjör, 300 credits). In the past I was the examiner for E0003E Electric circuit theory, D0011E Digital design, D0017E Introduction to programming for engineers. Before 2010 I taught several courses in physics.

Other

Some code and tools. Contact me if you are interested in code used in research articles that is not listed below.

• 3FCS code, link. This code was developed and used for the quark matter calculations in the papers about neutron stars with quark matter cores and related phase diagrams, including my most cited paper in Phys. Rev. D.
• Femtolensing tool, link. Calculates the gravitational lensing signatures of low-mass (10¹⁴-10¹⁷ kg) compact interstellar objects. This code was developed when working on the preon star hypothesis, see highlights below.
