Research Interests
I'm interested in cognitive modelling, cognitive robotics, cognitive neuroscience, artificial neural networks, artificial intelligence, human machine interaction, and the philosophy of mind. Currently I am a researcher in the multidisciplinary research environment Cognition, Communication and Learning (CCL). Within this research environment I work with a cognitive architecture aimed at improving understanding of internal simulation of perceptions and actions, computer models of episodic memory, and computer models related to eye movements. I am also a member of an advanced study group named The Meaning of Action at the Pufendorf Institute in Lund where I try to create computer models of intention reading. I also do research on Artificial Neural Networks (ANNs) and other kinds of machine learning, and I have invented some novel variants of the Self-Organizing Map (SOM). ANNs are very much employed in my cognitive models, but I'm also interested in ANN based applications and other machine learning applications, e.g. forecasting and medical diagnosis. I have done simulations of the re-organization of the somatosensory cortex after injuries to the nerves between the hand and the brain. This was done to get an idea about what kind of tactile stimulation should be provided after a surgical replantation of a lost hand in order to optimize the recovery. More about this here. I also work with bio-inspired haptic (tactile) perception in robots, and I'm interested in perception in general.
