Research Description

Dr. Freitas' lab has developed extensive expertise in the field of clinical/translational proteomics, biomarker discovery/validation and bioinformatics for mass spectrometry based proteomics. Their work focuses on the determination of side chain modifications of proteins important in Chromatin Remodeling and relating these modifications to aberrant cellular function in cancer.
