Education: PhD, University of Wisconsin-Madison

Nichole is an Assistant Professor in the Department of Biology. Prior to arriving at JHU, Nichole was an Assistant Professor in the Department of Molecular and Cell Biology and the Institute for Systems Genomics at the University of Connecticut. From 2013-2015, Nichole was an Associate Research Scientist at the Molecular, Cellular & Developmental Biology Department at Yale University. Nichole received her PhD from the University of Wisconsin-Madison with Ken Raffa (Entomology) NetBet sportand Jo Handelsman (Microbiology) and did her postdoctoral research in the lab of Bruno Lemaitre at the EPFL in Lausanne, Switzerland. Her research has focused on characterization of the gut microbiota of insect hosts and study of their impacts on host physiology and susceptibility to disease.


The goal of the Broderick Laboratory is to address fundamental questions related to animal biology by understanding the mechanisms that underlie animal-microbiome interactions. We use Drosophila melanogaster and its associated microbiota to study the impacts of beneficial and pathogenic bacteria on host development, physiology, and health using a variety of molecular, genetic, and genomic approaches.

Animals are in constant association with diverse and abundant microbial communities, collectively referred to as the microbiome. These interactions have important roles in animal development and physiology. Research in our lab seeks to address questions such as: How does the microbiome establish and maintain itself? What are the host and microbiota factors that mediate their interactions? How stable are these microbiome-dependent effects in response to perturbation by pathogens and time? Understanding the molecular basis of these interactions will inform our understanding of the evolution of host-microbe associations and define mechanisms that promote animal health.
