Research Overview:

Cell growth and proliferation are both necessary for successful immune reactions and dysregulated in many types of hematological malignancies. For cells to grow and proliferate, dramatic changes in the translation of mRNA to protein must occur.

My lab studies how cell extrinsic signals, such as growth factors or nutrient availability, regulate the process of mRNA translation to facilitate growth and proliferation of normal and malignant immune cells. By gaining insight into the highly regulated process of protein production in normal and malignant cells, we hope to uncover novel opportunities for therapeutic intervention that will preferentially target cancer cells.
