Jotham Suez

PRINCIPAL INVESTIGATOR
Jotham is a Feinstone Assistant Professor at the Johns Hopkins Bloomberg School of Public Health, Department of Molecular Microbiology and Immunology. His graduate work at the Weizmann Institute of Science, mentored by Prof. Eran Elinav, focused on microbiome-based rational design of therapeutics and diets. He aims to understand how microbes shape human health, promote diversity and equity in academia, and spend more time in nature with his dog Bono.

Haley Hallowell

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.

Katti Crakes

POSTDOCTORAL FELLOW
Katti completed her DVM and PhD at UC Davis with a focus on comparative medicine and developing animal models for human disease. Her research interests include host-microbe interactions and how they shape gut barrier function, metabolism, and immunologic response in communicable and non-communicable diseases in an effort to identify new therapeutic targets. She has a joint clinical appointment in the Department of Molecular and Comparative Pathobiology, where she is completing a residency in Anatomic Pathology. She claims life is never dull with her family, or "zoo”, which includes her son, partner, two dogs, and orange cat.

Yingying Ji

BMB SCM STUDENT
Yingying received her Bachelor of Health Sciences at Queen’s University. Working on the interaction between the gut microbiome and childhood asthma made her interested in the roles of the gut microbiome and the interactions between the various environmental factors and diseases. In her free time, she enjoys writing calligraphy, reading novels, and watching documentaries.

Weili Lu

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.
