Research in the Park laboratory revolves around the question, “How do environmental and endogenous physiological changes reprogram genetically hard-wired molecular pathways directing cell fate and function?” Park and his colleagues address this question by investigating signaling and gene regulatory events in immune disorders and cancer. The goal of this research is to determine the molecular underpinnings of human diseases and devise clinical strategies for their prevention and treatment. The major experimental approaches used in the Park laboratory involve genetic and pharmacological tools for the perturbation of molecular processes in various cell types and biochemical methods for their analysis.
