Todd Brusko is a Professor at Department of Pathology, Immunology and Laboratory Medicine and the scientific director at University of Florida Diabetes Institute (UFDI). The research aims of Dr. Brusko’s academic lab are centrally themed around understanding the mechanisms by which the immune system maintains a state of control, often referred to as immunological tolerance and understanding how genetic risk variants and age influence this process, as well as identifying pathway defects in individuals who develop autoimmune diseases. These studies have focused primarily on genes impacting key checkpoints in T cell activation, including T cell receptor (TCR) signaling, co-stimulation, and the IL-2 signaling pathway. His laboratory is involved a number of ongoing team science initiatives including an NIH-NIAID P01 grant, NIH Director’s Initiative – Human BioMolecular Atlas Program (HuBMAP), Brehm Coalition, and the JDRF biomarker working group and autoimmunity working group.

Paul Gadue is a Professor of Pathology and Laboratory Medicine at the Perelman School of Medicine at the University of Pennsylvania. His laboratory studies cell fate decisions, focusing on endoderm and mesoderm specification using human ES cells and iPS cells. ES/iPS cells can differentiate into all cell types in the body and can be propagated in culture almost indefinitely, generating a virtually unlimited supply of cells. These unique characteristics lead to the exciting prospect of using these cells to study disease processes and developmental pathways in vitro and eventually to treat a wide variety of diseases using cell replacement therapies.
