My research interest is focused on clinical and translational surgical infectious diseases research with specific interest in Musculoskeletal infectious diseases (MSK ID). My interest in this aspect of infectious disease started when I was in fellowship at the University of Maryland. During that time, I helped conduct a longitudinal prospective study evaluating the use of adjuvant intraarticular antibiotics in the treatment of recalcitrant prosthetic joint infections. This allowed me to gain knowledge in prosthetic joint infection treatments and in surgical infectious disease in general. I subsequently joined as faculty at the University of Maryland to further conduct clinical and translational research in surgical infections. Over the past six years I have started to test novel therapeutics in the treatment of prosthetic joint infections. These include the use of bacteriophages to treat recalcitrant prosthetic joint infections as well as other novel therapeutics. I have devised novel protocols to apply these agents clinically and have a patent pending for a protocol to use bacteriophages in the treatment of prosthetic joint infections. Moreover, I am the PI on a multicenter prosthetic joint infection clinical trial using adjuvant phage therapy that will start in 2022.
As well, I have spearheaded a novel study evaluating the use of calcium sulfate biodegradable antibiotic beads in the treatment of vascular graft infections and I am currently leading a project to test a novel diagnostic alpha defensins in the diagnosis of nosocomial ventriculitis. Beyond these research projects, I have treated numerous patients in novel ways to reduce morbidity and prevent mortality in these patients and have published some of these case reports. In addition, I am developing a MSK ID multidisciplinary team/approach here at the University of Maryland with the orthopedic department to reduce moribidiy and moratlity in MSK ID patients. Lastly, I have formed strong collaborations Dr. Ken Urish at University of Pittsburgh and Dr. Ben Chan at Yale University as well as other investigators in the USA and in Europe.
