Personal profile

Public Profile

Pirjo has an international track record and a long term interest in protein networks regulating membrane trafficking disorders and proteostasis.

After completing a Ph.D. in processing and trafficking of G protein-coupled receptors in Finland, she continued her research into conformational diseases and protein trafficking disorders at the Hospital for Sick Children Research Institute, Toronto. As a senior scientist at McGill University, Montreal, Canada she further specialized in the regulation of the endo-lysosomal pathway, ubiquitin signalling and their role in the protein trafficking disorders leading to cancers, cystic fibrosis, astrocyte dysregulation and heart defects. Pirjo is currently EMBL Australia Group Leader in Organelle Biology and Disease at the South Australian Health and Medical Research (SAHMRI), Adelaide and Associate Professor in Molecular and Biomedical Sciences at the University of Adelaide.

Pirjo’s Organelle Biology and Disease Group is an experimental research group and is working towards understanding how protein networks and post-translation modifications especially ubiquitination and conditional stress regulate intracellular pathways such as endolysosomal-autophagy pathway, and how dysfunction in these pathways can lead to disorders. Her group employ advanced light microscopy to measure protein trafficking, signalling and organelle pH regulation, proteomics, network analyses and other biochemical and cell biological methods. Her group is investigating protein networks involved in cancers, Parkinson’s and behavioural diseases and in astrocyte stress reponses. The aim of her research programme is to find targets at the intracellular level.
