Dr. Amin is an anatomic and clinical pathologist who has conducted research in the areas of angiogenesis, carcinogenesis and radiation-induced lung disease. He has also pursued studies of various human diseases in animal models, in vivo toxicology assays, and preclinical drug development of anti-cancer drugs in collaboration with the biotechnology industry. Amin was part of a collaborative research group that discovered a link between the clinical use of synthetic erythropoietin (EPO) and risk of tumorigenesis. He and his colleagues showed that tumor cells have cell-surface receptors for EPO, which can stimulate tumor cells to proliferate and enhances the formation of new blood vessels in tumors.

Recently, Amin has collaborated with clinical colleagues in studies of cyroprobe lung biopsy, a new tool in diagnosing lung diseases; endoscopic ultrasound-guided fine needle aspiration as a diagnostic and staging tool for rectal and perirectal lesions; and the value of ex vivo dermoscopy of cutaneous biopsies in the histopathologic diagnosis of melanoma. He also collaborated in studies showing that the metal-responsive transcription factor-1 (MTF-1) zinc finger protein is elevated in human tumors, suggesting a role for MTF-1 in human carcinogenesis. As a cytopathologist he has a special interest in defining the role of molecular testing in diagnosis of thyroid cancer on cytology specimens. Although Amin is currently engaged mostly in clinical work, he has an interest in pursuing translational research in collaboration with clinicians and basic scientists.
