Dr. Harvey Cohen's research interests extend from hypothesis-driven studies in biochemistry and cell biology to discovery-driven interests in proteomics and systems biology to clinical treatment of acute lymphoblastic leukemia of children.

The lab's biochemical studies have centered on the identification and characterization of members of the glutathione peroxidase family of antioxidant enzymes that contain an enzymatically active selenocysteine residue within the primary structure of the protein.
