Joseph Locker

Joseph Locker, MD, PhD is Professor of Pathology at the University of Pittsburgh School of Medicine, with dual appointments in the Division of Experimental Pathology and Division of Molecular & Genomic Pathology. His research integrates basic transcriptional mechanisms with clinical pathology, focusing on liver disease processes.

Dr. Locker's research interests center on liver transcriptional regulation, specifically examining how nuclear receptors like CAR and HNF4 control hepatocyte proliferation and metabolic functions. His work distinguishes cancer-promoting hyperplasia from natural regeneration processes, and investigates transcriptional deregulation in cirrhosis. Current projects utilize NextGen sequencing methodologies for genome-wide characterization of gene expression and chromatin remodeling.

His publication record shows consistent productivity from the 1970s through 2025, with recent work spanning liver disease mechanisms, cancer biology, and molecular diagnostics. Research trends indicate increasing integration of genomic methodologies with traditional pathological analysis.

As an active NIH-funded investigator, Dr. Locker maintains laboratory operations focused on translational research bridging molecular mechanisms with clinical applications in liver disease. His work provides fundamental insights into transcriptional control of liver regeneration and cancer promotion, with potential therapeutic implications for cirrhosis and hepatocellular carcinoma.

Dr. Locker's clinical expertise includes molecular diagnostics, analysis of mutations and translocations, anatomic pathology, and immunohistochemistry. His dual MD/PhD training enables effective translation of basic research findings into clinical applications.
