Joana Almaça is a HIRN New Investigator and an Assistant Professor of Medicine at the University of Miami Miller School of Medicine. Her current research focuses on the vasculature of the islet. In her work, Dr. Almaça is testing the hypothesis that microvascular dysfunction in the islet leads to a disturbance of hormone secretion, to glucose intolerance, and eventually to diabetes.

Juan Alvarez is a HIRN Emerging Leader Award Recipient and an Assistant Professor of Cell and Developmental Biology at the University of Pennsylvania Perelman School of Medicine. His research focuses on human stem cell-derived pancreatic islet organoids and mice as model systems to study islet development, physiology, and pathology, and to develop replacement therapies for insulin-dependent diabetes. We focus on the interplay between circadian rhythms, metabolism, and islet cell maturation.

Leonardo Ferreira is a HIRN Emerging Leader Award Recipient and an Assistant Professor of Microbiology and Immunology at the Medical University of South Carolina. His research focuses on phenomenon of immune tolerance, his long term goal is to control how the immune system defines self and non-self. Such knowledge will allow the design and development of powerful new engineered immune cell therapies to fight autoimmune disease, cancer, and aging.
