Dr. Joel L. Pomerantz is an associate professor of biological chemistry at the Johns Hopkins University School of Medicine. His research focuses on functional specificity and the design of signal transduction pathways.
Dr. Pomerantz received his B.A. in biochemistry from Brandeis University in 1989 and completed his Ph.D. in biology in Phillip A. Sharp's laboratory at the Massachusetts Institute of Technology in 1995. He then completed two postdoctoral fellowships in biology, the first one at MIT with Carl O. Pabo in 1997 and the second in David Baltimore's laboratory at the California Institute of Technology in 2003. He joined the faculty of Johns Hopkins in 2004.
His work examines the molecular machinery used by cells to interpret extracellular signals and transduce them to the nucleus to effect changes in gene expression, which results in a cell's decision to proliferate, differentiate, or die. The dysregulation of this machinery underlies the unwarranted expansion or destruction of cell numbers that occurs in human diseases like cancer, autoimmunity, hyperinflammatory states and neurodegenerative disease.
Dr. Pomerantz is a member of the American Society for Microbiology and the American Society for Biochemistry and Molecular Biology, and serves on the editorial boards of Molecular and Cellular Biology and the Journal of Biological Chemistry. He has authored or co-authored several peer-reviewed articles and one book chapter, has received numerous grants and awards and holds two patents.

Research & Publications
Dr. Pomerantz and members of his lab currently study signaling pathways that are important in innate immunity, adaptive immunity, and in cancer, paying particular attention to pathways that regulate the activity of the pleiotropic transcription factor NF-kappaB. One molecule that signals to NF-kappaB is CARD11 and the team is investigating the biochemical mechanisms by which CARD11 transduces signals from the T-cell receptor to NF-kappaB. Using a new expression cloning strategy designed to isolate molecules that signal to NF-kappaB in lymphocytes, the team has cloned several novel signaling molecules that activate the NF-kappaB or NFAT transcription factors and is currently working to better understand their mechanisms of action.
Dr. Pomerantz and his team are also interested in the design of artificial cellular signaling circuits, which would provide new tools for controlling gene expression to be used in biological research and to engineer cell fate decisions in novel therapeutic approaches.
