Rate My Professor Pamela Tuma

Pamela L. Tuma, Ph.D., serves as Professor and Chair of the Department of Biology within the School of Arts and Sciences at The Catholic University of America. She earned her Ph.D. from Northwestern University Medical School. Dr. Tuma's research focuses on hepatic protein trafficking, polarized membrane sorting in hepatocytes, alcohol-induced liver injury, microtubule dynamics and acetylation, epithelial-mesenchymal transition in hepatocellular carcinoma, peroxisome responses to hepatic injury, and the roles of tumor suppressors such as MAL2 and rab17. Utilizing polarized hepatic cell models like WIF-B cells, her laboratory investigates how alcohol disrupts protein sorting, endocytosis, and intracellular trafficking, contributing to the pathogenesis of alcoholic liver disease. She actively mentors graduate, undergraduate, and high school students, integrating them into her research projects that explore mechanisms of liver damage and potential therapeutic interventions.

Dr. Tuma has authored or co-authored over 94 publications, accumulating more than 4,000 citations as documented on Google Scholar, where her profile highlights expertise in cell biology, hepatology, pathology, and molecular biology. Key publications include 'Vps34p differentially regulates endocytosis from the apical and basolateral domains in polarized hepatic cells' (2001), 'Alcohol-induced protein hyperacetylation: Mechanisms and consequences' (2009), 'Alcohol consumption impairs hepatic protein trafficking' (2010), 'Alcohol-induced tubulin post-translational modifications generate hyperstable microtubules' (2023), 'Distinct peroxisome populations differentially respond to alcohol-associated hepatic injury' (2024), and 'MAL2 and rab17 selectively redistribute invadopodia proteins to laterally-induced protrusions in hepatocellular carcinoma cells' (2025). As department chair, she leads faculty recruitment, oversees graduate programs such as Cellular and Microbial Biology, and promotes a research-oriented environment. Her contributions extend to providing cell lines and expertise to collaborators worldwide, enhancing studies on liver pathology and alcohol-related disorders. Dr. Tuma was featured as a corresponding author in the American Society for Cell Biology Pathways newsletter.
