My main research interest is nonlinear inference, especially within the context of dynamical systems, solved using probabilistic models and algorithms. In terms of scientific fields, my research is situated somewhere on the intersection between the fields of machine learning, signal processing and automatic control. My aim is to pursue both basic and applied research, where the latter is typically carried out in close collaboration with industry. A brief overview of my research is available here and my publications are available here.

Recent research results/news

June 10, 2016: We (Pierre Jacob, Fredrik Lindsten and myself) have developed a new coupling construction for particle filters and conditional particle filters. The coupled particle filter improves the performance significantly for example when it comes to computing gradients and using it inside the particle Metropolis Hastings algorithm. When the coupled conditional particle filter is combined with a recent debiasing technique we obtain a new smoothing strategy with the appealing properties of 1) straightforward parallelization and 2) the construction of accurate error estimates. Neither of the above is possible with existing particle smoothers. All the details are available in this arXiv:ed paper:

April 12, 2016: Our project ASSEMBLE goes live! We will work on automating machine learning and bringing powerful algorithms (like Sequential Monte Carlo) to the users. The project is funded by The Swedish foundation for strategic research. The partners are David Black-Schaffer (Uppsala university), Joakim Jaldén (KTH) and David Broman (KTH). Link to SSF announcement.
