Dr. Blazer is an Assistant Professor in the University of Maryland Division of Rheumatology. She co-directs the Lupus Center at the University of Maryland School of Medicine. She has investigated systemic lupus erythematosus (SLE) since her fellowship training in 2013, and her laboratory conducts bench-to-bedside translational research aimed at understanding genetic and functional genomic factors impacting SLE pathogenesis in African ancestry patients. Dr. Blazer's lab models genetic risk using SLE peripheral blood mononuclear cells (PBMCs) and vascular endothelial cells to understand the interplay between the inflammation seen in SLE and cellular injury. 

The Blazer Lab has been instrumental in understanding how common mutations in the Apolipoprotein L1 (APOL1) gene increase the risk of vascular disease, kidney disease, and SLE associated organ damage in African ancestry patients. Her translational research lab has shown that SLE-relevant inflammation increases cellular production of APOL1 which, in genetic mutation carrying cells, causes defects in mitochondrial health and inability to complete a cellular maintenance process called autophagy. Importantly, current clinical testing cannot distinguish between kidney injury caused by SLE and kidney injury caused by APOL1 gene mutations. In collaboration with West African physician scientists, the Blazer Lab now aims to use epigenetic profiling on cellular debris present in the urine to identify biomarkers of SLE nephritis and APOL1 associated nephropathy. 

Dr. Blazer supports her research through NIH funding as well as funding from foundations such as the Lupus Research Alliance and The Rheumatology Research Foundation. She has been a dedicated champion of health equity particularly in the African American community. She is passionate about research, teaching, and medical communication, and is active in community outreach and education through multiple national organizations.
