I am an immunologist working in the field of innate immunology, which can be broadly defined as the set of molecular immune defenses each of us is born with prior to encountering any specific infection out in the world.
I began my research in innate immunology beginning with my doctoral work at Emory University where I studied the ways in which cells detect infection by RNA viruses and how host protein synthesis is controlled as a defense mechanism to restrict viral growth.
Subsequently, as a post-doctoral fellow with Dr. Stefanie Vogel I studied the ways in which the innate Toll Like Receptors (TLRs) sense many types of bacterial pathogens and orchestrate complex patterns of inflammation to clear infections
At the University of Maryland Baltimore, I am jointly appointed within the Department of Microbiology and Immunology in the School of Medicine and as a scientist within the Greenebaum Comprehensive Cancer Center

The Perkins laboratory at UMB is focused on fundamental questions about how the human innate immune system maintains a constant surveillance for infection by a vast array of microbes (viral, bacterial and fungal) as well as simultaneously searching for signs of malignant tumor formation. We are particularly interested in the roles of innate pattern recognition systems and the regulation of key genes driving an inflammatory response.
Overall we try to create an aspirational environment that fosters both trainee progress and concept development in innate immunology in a data driven manner
