Dr. Hollenbach’s research focuses on analysis of the human leukocyte antigen (HLA) and killer immunoglobulin-like receptor (KIR) immunogenetic systems. Beside their critical role in transplantation, over 100 infectious, autoimmune, cancer and pharmacological diseases are associated with variation of HLA and KIR. Her work spans the population genetics, evolution, and influence on health of these genes, with emphasis on their role in neurological disease. Her lab also develops software tools specifically designed for these data. Other projects include examination of alternative measures of self-reported ancestry with respect to genetics, and the relationship between patient-reported and clinician-defined disability in multiple sclerosis.
