About Per O.

Per O. Ljungdahl is Professor in Cell Biology at Stockholm University, affiliated with the Department of Molecular Biosciences, The Wenner-Gren Institute, and serves as Director of SciLifeLab Campus Solna. His research group, located at SciLifeLab Campus Solna, investigates the metabolic and spatio-temporal determinants of fungal virulence in opportunistic pathogens such as Candida albicans and Candida auris. Key focuses include proline catabolism, which provides energy for filamentation and tissue invasion, mitochondrial processes critical for fungal survival, and host-pathogen interactions visualized through intravital 2-photon microscopy, STED microscopy, and spatio-transcriptomic analysis. Ljungdahl's work has revealed that proline metabolism, derived from host collagen, is essential for Candida virulence in kidney infections, with strains lacking proline catabolic enzymes exhibiting reduced hyphal formation and invasiveness.
