Nick Giannoukakis, PhD
Associate Professor of Pathology
Dr. Giannoukakis is a member of the Division of Experimental Pathology and a member of the Cellular and Molecular Pathology Graduate Training Program. He teaches topics on pancreas and thyroid development and pathology as well as cell and gene therapy approaches in diabetes mellitus in a number of courses administered by the Department and also directs the "Introduction to Immunobiotherapeutics" course in the Department of Immunology. He has mentored graduate, MD/PhD students as well as clinical fellows over the years and is one of the founders of DiaVacs, a biotechnology entity leveraging dendritc cell therapy for autoimmunity.
