### Malte Höltershinken

### Alexandra Koulouri

I am an Academy of Finland Post-doc researcher in the Inverse Problems Group of Tampere University. My main research areas of interest are machine learning, data assimilation, convex/non-convex optimization, deconvolution problems, adaptive meshing and uncertainty modelling using Bayesian statistics in inverse problems. In Inverse Days, I will present my latest work about using an ensemble of Kalman filters and data-based learning techniques to produce high spatio-temporal sequences of images from limited observations. As an application, I will show how to construct real-time images of ionospheric scintillation which are very useful in evaluating the reliability of the GNSS positioning system.

### Lauri Mehtätalo

Lauri Mehtätalo has recently started as a professor in mathematical modelling for forest planning at Natural Resources Institute Finland (Luke). He did his PhD in forest mensuration in 2004, and has forked thereafter, for example, as university researcher in forest planning and professor in applied statistics at University of Eastern Finland. He has recently authored with Juha Lappi a textbook “Biometry for Forestry and Environmental Data: With Examples in R” to CRC Press.
