Forskningsområder

Modeling and control in biophysical systems.

- Cybernetics and control theory in biochemical, biophysical, and physiological processes.

Control theory is applied to enhance understanding of biochemical mechanisms behind robust adaptation and homeostasis, especially the ability to perform homeostasis under oscillatory conditions. The work includes identifying model structures leading to robust homeostasis and/or oscillatory performance together with simulation of nonlinear systems and nonlinear analysis of biophysical systems from a control theoretic point of view.
