Biographical Sketch 
Daniel Bullard, Professor of Genetics, received his Ph.D. in 1992 from Case Western Reserve University in the field of genetics. During his postdoctoral studies in the Department of Human and Molecular Genetics at Baylor College of Medicine in Houston, he initiated research investigating the roles of leukocyte/endothelial cell adhesion molecules in inflammatory diseases such as lupus, psoriasis, and rheumatoid arthritis. He has continued this work in his laboratory at UAB. Dr. Bullard has also been very active in graduate education. Since coming to UAB in 1996, he has helped start three new graduate programs and currently serves as the Director of the Genetics, Genomics, and Bioinformatics (GGB) theme. In addition, he has developed six graduate level classes related to genetics and genomics, and has mentored many different postdoctoral fellows, graduate students, and undergraduate students in his laboratory.

Research/Clinical Interest
Regulation of Immune and Inflammatory Responses
My research has focused for the last 20 years on defining the cellular and genetic mechanisms by which adhesion molecules, such as the B2 integrins, ICAM-1, and the selectins regulate immune and inflammatory processes, especially during the development of chronic inflammatory disorders. Specific diseases of interest include systemic lupus erythematosus, rheumatoid arthritis, vasculitic disorders, multiple sclerosis, and psoriasis. I have extensive experience with the generation and characterization of both transgenic and gene targeted or knockout mutant mice, and through these efforts have developed an extensive set of adhesion molecule deficient mice. I have also analyzed many of these mutant lines in disease models including SLE-susceptible MRL/MpJ-Faslpr mice, collagen-induced arthritis (CIA), and experimental autoimmune encephalomyelitis (EAE). This work has identified new functions and unexpected roles for adhesion molecules in regulating the initiation and progression of autoimmunity and tissue inflammation. In addition, my lab has recently initiated a major functional genomics initiative designed to determine whether genetic variants in the ITGAM (CD11b) gene, which have been shown in multiple GWAS studies to be strongly associated with the development of lupus, potentially alter the expression, ligand binding, and function of Mac-1. The long-term goal of these studies is to determine how these ITGAM variants contribute to the pathogenesis of SLE.
