Dr. Raj completed his doctoral training from JU, Gwalior, India. His Ph.D. thesis work was focused on epidemiological and genetic analysis of pulmonary tuberculosis in tribal groups of central India. One of the interesting findings from this work was establishment of LDH2 & LDH3 isoforms as markers of mycobacterial infection load induced cellular stress in TB patients. His research showed that noncoding genetic polymorphisms in Vitamin D receptor (VDR) gene are associated with clinical manifestations of pulmonary TB.
During his postdoctoral training in Wakeland laboratory in the department of immunology at UT Southwestern Medical center, he investigated genetic basis of Systemic Lupus Erythematosus (SLE). Using deep targeted sequencing approach, he made an important discovery demonstrating abundance of SLE associated noncoding, regulatory variations at HLA locus that impact transcription of several key genes of immune system that activate antigen presentation pathway to potentiate autoimmunity in individuals with risk genotype.
Dr. Raj, joined the faculty of Immunology at UT Southwestern Medical Center in September 2018. He is the Director of newly established Microbiome Research Laboratory (MRL) that provide cutting edge facilities to investigate and characterize communities of microorganisms sampled from variety of sources. Dr. Raj and his team at MRL provide microbial sequencing services to basic and translational investigators that are interested in microbiome research.
