Marina Parezanović is a Research Assistant in the Group for Rare Disease Research and Therapeutics Development at the Department of Human Molecular Genetics and Genomics at IMGGE. Her research focuses on rare metabolic diseases, particularly glycogen storage disease type Ib (GSD Ib), through the development of in vitro model systems and the investigation of small-molecule effects. She is also involved in the molecular-genetic diagnostics of rare diseases.

As a part of her experimental work for PhD thesis, Marina is generating stable CRISPR/Cas9‑edited cell lines to model GSD Ib, providing genetically defined platforms for systematic phenotypic studies. Concurrently, she reprograms somatic cells into induced pluripotent stem cells (iPSCs), differentiates them into hepatocyte-like cells, and validates the models by assessing disease-relevant metabolic and functional features. Within these engineered in vitro GSD Ib systems, small-molecule compounds are systematically evaluated for their therapeutic potential.

Marina earned her Bachelor's degree in Molecular Biology and Physiology from the Faculty of Biology, University of Belgrade, in 2020, followed by a Master's degree in Experimental Biomedicine in 2021. Since enrolling in the PhD program in Molecular Biomedicine at the Faculty of Biology in 2021, she has been working at IMGGE and became Research Assistant in 2025.
