Dr. Nicosia is staff pathologist and director of electron microscopy at the VA Puget Sound Health Care System (VAPSHCS) and UW professor of pathology. He is an expert in renal pathology and member of the UW renal pathology team. Dr. Nicosia conducts research on angiogenesis, the process of formation of blood vessels. His research focuses on the role of the innate immune system and oxygen levels in angiogenic regulation. He has a special interest in the mechanisms by which the immune system and hypoxia influence the growth and survival of newly formed blood vessels.

Dr. Nicosia earned his M.D. degree from La Sapienza University in Rome, Italy and his Ph.D. from the Medical College of Pennsylvania in Philadelphia. After working for 20 years at the Medical College of Pennsylvania and Hahnemann University (later named Allegheny University of the Health Sciences through a merger), he moved to Seattle to direct the laboratory of VAPSHCS and join the University of Washington in 1999. He is a member of the United States and Canadian Academy of Pathology and the American Society of Investigative Pathology and is board certified in anatomic and clinical pathology. He is also a member of the editorial board of the journal “Angiogenesis."

Patient Care Philosophy

My clinical practice focuses on renal pathology, a discipline that allows me to interact closely with doctors who take care of patients with medical diseases of the kidneys. A particularly exciting aspect of my work is the ability to actively contribute to treatment decisions through the identification of pathologic alterations on kidney biopsies.

Clinical Interests

Renal pathology; angiogenesis-dependent diseases; diagnostic electron microscopy.

Research Interests

Angiogenesis; wound healing; atherosclerosis; renal pathology.
