Caspar Wistar Fellow, HIV Cure and Viral Diseases Center
Colby Maldini, Ph.D. is an immunologist specializing in cellular immunotherapy for infectious diseases and cancer. He obtained a B.S. degree in Biological Chemistry from Bates College (Lewiston, ME) and received his Ph.D. in Cell and Molecular Biology from the University of Pennsylvania (Philadelphia, PA). Maldini joined The Wistar Institute’s HIV Cure and Viral Diseases Center as a Caspar Wistar Fellow in February 2025.
The Maldini Laboratory
The Maldini Laboratory
The Maldini Lab leverages emerging genome engineering technologies to address challenges in immunotherapies and enhance their functionality for next-generation treatments. By integrating gene-editing technology such base editing systems with synthetic biology, we aim to overcome therapeutic resistance, improve safety and expand the application of engineered immune cells to treat serious human diseases.
