SENIOR RESEARCH ASSOCIATE

Hua manages the Johns Hopkins Germ-free Mouse Core Facility, which supplies germ-free mice for investigators to study microbiome impact in a variety of fields.

POSTDOCTORAL FELLOW

Haley received her PhD in Biology from Auburn University. Her research interests lie in understanding how bacteriophages influence the form and function of the microbiome, host immune responses to bacteriophage, and disease-mediated effects on intestinal bacteriophage populations. In her free time, she enjoys hiking with her dog, Luna, playing DnD, crafting, and watching Survivor.

RESEARCH SPECIALIST

Yingying received her Master of Science at Johns Hopkins University and her Bachelor of Health Sciences at Queen’s University. Working on the interaction between the gut microbiome and childhood asthma sparked her interest in the roles of the gut microbiome and in the interactions between various environmental factors and diseases. In her free time, she enjoys writing calligraphy, reading novels, and watching documentaries.

UNDERGRADUATE STUDENT

Weili is a Woodrow Wilson Fellow and an undergraduate at Johns Hopkins University majoring in Biophysics. Ever since a high school research project involving duck poop sparked his interest in the gut microbiome, he has been fascinated by the role of host-microbe interactions (not just limited to bacteria!) in contributing to metabolic and other diseases. In his free time, Weili is a birdwatcher, cellist, tennis player, and a sunrise/sunset enjoyer. 

UNDERGRADUATE STUDENT

Sophia is an undergraduate at Johns Hopkins University studying Molecular and Cellular Biology & Medicine, Science, and the Humanities. Her high school capstone project on IBS and the low-FODMAP diet sparked her interest in gut physiology and the far-reaching impacts of the microbiome, especially in response to diet. In her free time, she loves to play the cello, ultimate frisbee, and bake.
