Personal Statement

Dr. Amoscato has a wealth of experience in mass spectrometry of lipids (lipidomics), peptides, proteins (proteomics), small molecules (metabolomics) and imaging mass spectrometry. He has applied these areas of mass spectrometric expertise to the study of lipid-protein/protein-protein interactions, lipid alterations and phospholipid signaling during apoptosis and autophagy. His main interests include mechanisms of apoptosis, autophagy and ferroptosis, mitochondrial and redox biochemistry as well as the role of oxidized lipids in these modes of cell death and. He is also interested in the role of sphingolipids in radiation-induced apoptosis; the role of sphingolipids in androgen ablation induced apoptosis of prostate cancer cells; the role of lipids and lipid signaling in endothelial cell apoptosis and the role of lipid DAMPS in inflammation and cancer.
