Eric P. Hanson, MD, received his bachelor’s in biomedical engineering at Brown University, post-baccalaureate training in basic immunology research studying Severe Combined Immunodeficiency at NIH, and MD degree at the University of Pittsburgh. He subsequently completed his residency in pediatrics at St. Christopher’s Hospital for Children in North Philadelphia and subspecialty training in rheumatology at the Children’s Hospital of Philadelphia.

During fellowship, Hanson pursued translational research and clinical immunology training by undertaking a project to better study and understand a rare genetic primary immunodeficiency called NEMO Syndrome. Hanson then joined the faculty at the National Institutes of Arthritis, Musculoskeletal and Skin Diseases in Bethesda, MD, where he completed postdoctoral training, ran a clinical trial, and established a diagnostic and evaluation program to study individuals with complex immune dysregulation syndromes that predominantly affect the NF-kB signaling pathway.

His research has more recently focused on understanding biochemical and molecular mechanisms by which inflammatory disease is triggered and persists in a chronic state. In addition to ongoing genetic discovery research involving human subjects, his lab is developing several knock-in mouse models and in vitro model systems to investigate pathophysiology and novel therapeutic approaches to these diseases.

In addition to lab PI, Hanson is also the division chief of pediatric rheumatology at IU School of Medicine and Riley Hospital for Children, one of the pre-eminent training programs in the country.

Dongbing Lai is a statistical geneticist. His research interests are searching for genes related to common and rare diseases, and understanding how these genes cause diseases. These include using genomic data (genome-wide genotype data, whole exome sequencing data, and whole genome sequencing data) to perform genetic studies and identify disease causing genes; then using other omics data (transcriptomics, methylomics, metabolomics, etc.) to investigate the roles of these genes in disease causing.
