Xincheng Wu is a Ph.D. candidate in Molecular Nutrition at Cornell University. His research focuses on understanding how mRNA translation is regulated under metabolic stress, particularly how arginine availability influences protein synthesis and cell metabolism. He combines techniques such as ribosome profiling, confocal microscopy, and proteomics to uncover molecular mechanisms that link translation control to cancer cell growth. His work also explores how tumor-derived mRNAs are translated in normal somatic cells to advance mRNA-based immunotherapies
