معرفی
Richard A. Rachubinski is a Professor in the Department of Cell Biology at the University of Alberta, Faculty of Medicine & Dentistry. He conducts cutting-edge research on peroxisome biogenesis and related human genetic disorders, utilizing model systems including yeast and Drosophila. His laboratory is located in the Medical Sciences Building, where he leads a research team investigating the molecular mechanisms of organelle formation and inheritance.
Dr. Rachubinski earned his Ph.D. from McGill University and has established himself as a leader in cell biology. His work bridges fundamental cellular processes with clinical implications for peroxisome biogenesis disorders (PBDs), which are severe and often lethal conditions in humans.
His research focuses on the molecular cascade of peroxisome biogenesis, leveraging global approaches such as differential gene expression analysis, proteomics, fluorescence microscopy, and subcellular fractionation. He studies how peroxisomes form from the endoplasmic reticulum, how they divide and are inherited during cell division, and how their dysfunction leads to disease. His lab uses Yarrowia lipolytica, Saccharomyces cerevisiae, and Drosophila as model organisms, capitalizing on their genetic tractability and evolutionary conservation of peroxisomal mechanisms.
The analysis of his recent publications reveals a strong focus on organelle dynamics, membrane contact sites, peroxin functions, and disease modeling. His work spans molecular mechanisms of protein import, organelle population control, lipid droplet inheritance, and immune-metabolic crosstalk, reflecting a multidisciplinary and systems-level approach to cell biology.
