# overview
Dr. Galloway-Pena's studies incorporate the genetic basis of pathogenesis as well as the molecular epidemiology of clinically relevant gram-positive pathogens, focusing on those with multi-drug resistance. She has more recently shifted her focus to microbiome dynamics during cancer treatment and the intense antibiotic therapy seen in the hematological malignancy setting to determine the microbiome's impact on cancer treatment outcomes, toxicities, and colonization/infection by antibiotic resistant organisms. Applications of her research include determining genetic and chemical markers for microbial diversity that can be used in the clinical setting, designing predictive risk models for antibiotic resistant infectious risk during chemotherapy, and promoting antimicrobial stewardship and microbial conscious treatment.
