About me

Understanding Cellular Dynamics

Our research group investigates the fundamental physical principles that govern biological processes at the cellular level. We seek to understand the cell's complex energy landscape and how protein interactions contribute to integrated physiological functions and organismal diversity.

A central focus of our research is the Na,K-ATPase, a vital ion pump responsible for intracellular homeostasis. We have pioneered the field of Na,K-ATPase signaling, elucidating how the endogenous ligand ouabain triggers intracellular calcium oscillations. These signals have been demonstrated to play critical roles in cellular stress response, including protection against apoptosis in various pathological conditions.

Current projects explore topics such as the Na,K-ATPase catalytic subunit's allosteric regulation, interactions between Na,K-ATPase and IP3R, and functional oligomerization of the pump. Advanced imaging techniques are integral to our research methodology.

We are leaders in microscopy innovation, developing super-resolution and hyperfast volume imaging methods. Our group operates the national super-resolution microscopy infrastructure at the Science for Life Laboratory. Additionally, we coordinate the National Microscopy Infrastructure (NMI)  https://www.nmisweden.se and represent the Swedish node in EurobioImaging https://www.eurobioimaging.eu.

Our team fosters a cross-disciplinary environment, with members from KTH and Karolinska Institutet. We integrate advanced light microscopy with cell and molecular biology approaches to advance our understanding of life's fundamental processes.
