Biographical Sketch 
Dr Bebok completed her medical degree and a residency program in Pathology and Histopathology at the University Medical School of Pecs, Hungary. As a student and later as faculty member, she worked under the guidance of Dr. Peter Nemeth at the Department of Immunology at the University Medical School of Pecs, Hungary. In 1993, she started a postdoctoral fellowship at the Department of Physiology, University of Alabama at Birmingham under the mentorship of Dr. Eric Sorscher. As junior faculty at the Department of Medicine at UAB, and associate scientist of the Cystic Fibrosis Research Center, she worked on the cellular and molecular mechanisms underlying cystic fibrosis. She joined the Department of Cell Biology in 2002. Dr. Bebok's research concentrates on cellular and molecular mechanisms by which cellular stress responses contribute to the development of human disorders. In addition to research, she has a passion for teaching and mentoring students. Dr. Bebok has decades of experience teaching at UAB. She lectured and directed courses in the Schools of Medicine, Dentistry, Optometry and Health Professions. She serves as co-director of the UAB General Biomedical Sciences (GBS), Genetics, Genomics and Bioinformatics (GGB) PhD Theme since 2016. At the national level she serves on Scientific Review Panels for the National Institute of Health.

Research/Clinical Interest
Molecular mechanisms by which cellular stress responses such as the unfolded protein response (UPR) contribute to the pathology of human disorders.
Our earlier studies concentrated on 1) cellular mechanisms that reduce endoplasmic reticulum (ER) protein load during the unfolded protein response (UPR) to alleviate ER stress and 2) how mutations and single nucleotide polymorphism affect mRNA structure and co-translational protein folding. ER stress and activation of the UPR contribute to the pathogenesis of a wide range of human disorders including cystic fibrosis, chronic obstructive pulmonary diseases (COPD), diabetes mellitus, and chronic kidney disorders. Thus, understanding the molecular pathways of cellular stress responses will provide important clues for the development of molecular therapies. Our second project investigated how synonymous mutations such as single nucleotide polymorphisms (SNPs) affect mRNA structure, co-translational protein folding and consequently protein function. We have demonstrated that one synonymous change in the CFTR gene alters mRNA structure and affects translation. Our recent studies concentrate on the mechanisms by which cellular stress responses are communicated between cells in different tissues and how they contribute to disease pathogenesis.
