Current research activities:

Easier use of «never-ending» megavariate data streams, e.g hyperspectral video.
New methods for model development in nonlinear dynamics.
Industrial use of modern high-dimensional sensors, e.g. Thermal video.
New ways to reach the creative and the empathic student personality types wrt math and statistics, with a focus on valid overview, discovery and meaning, rather than proofs and exactness.
How reduce math anxiety in socity.
How to replace "black box" AI solutions with "human-interpretable machine learning. with an eye for causality" in the use of Big Data in Science and Technology.
How to combine the best of mechanistic, theory-driven modelling and pragmatic, data-driven modelling.
