About me
I am a principal research engineer at Linköping University, Sweden. My research interest is in the field of artificial intelligence, with a focus on classical planning. Currently, I am researching how neural networks can be used to learn generalized policies so that entire classes of planning instances can be solved.
Short bio
I have done all my studies at Linköping University: I completed my bachelor's and master's degree in computer science in 2010 and 2012, respectively; and I received my PhD in 2017. After my studies, I worked in the industry for a while, and I resumed my research when this lab was founded.
