Ricardo Rajsbaum, PhD is an Assistant Professor in the Department of Microbiology and Immunology at the University of Texas Medical Branch, Galveston, Texas. Dr. Rajsbaum performed his PhD in the laboratory of Anne O’Garra at the MRC-NIMR, London, UK, and completed his postdoctoral training at Mount Sinai School of Medicine, New York, with Dr Adolfo Garcia-Sastre. Dr. Rajsbaum’s lab at UTMB studies regulation of cytokine expression in immune cells, TLR and RIG-I-like receptor signaling, regulation and function of type-I IFNs, and virus–host interactions, with a specific focus on the role of ubiquitin and TRIM E3-ubiquitin ligases in innate antiviral function. Current research is focused on the role of TRIM6 during infections with highly pathogenic viruses (Ebola and Nipah; Bharaj et al., PLoS Path, 2016; Bharaj et al., J. Virol 2017), the role of the ubiquitin system in promoting Zika and dengue virus replication, and the role of unanchored polyubiquitin chains in regulation of innate immune signaling.
