Justyna comes from Poland. She obtained her Bachelor’s degree in Biotechnology at the University of Wroclaw, where she studied expression profiles of selected genes of the biosynthetic gene cluster of the novel aminocoumarins cacibiocin A and B. She continued her Master’s studies in the group of Prof. Jolanta Zakrzewska-Czerwinska at the Department of Molecular Microbiology, University of Wroclaw. During her Master thesis she identified and studied a new protein involved in the regulation of replication initiation and differentiation in Streptomyces coelicolor. After graduation, Justyna moved to Germany and started an internship in Prof. Lothar Willmitzer’s group at the Max Planck Institute for Molecular Plant Physiology in Potsdam. She focused on validating the interaction partners of pantothenic acid and methylthioadenosine using microscale thermophoresis and thermo stability assays. Justyna also gained substantial experience in working with mass spectrometry-based metabolomics, which she made use of when she moved to China in 2018, where she participated in setting up a new mass spectrometry unit at Metanotitia, a Chinese metabolomics company in Shenzhen. In July 2020, Justyna returned to academia and joined the Bremm laboratory as PhD student. She is now investigating the functional role of deubiquitylases in selective autophagy pathways.
