The faculty of the Mucosal Immunology and Biology Research Center (MIBRC) includes experts in the study of mucosa and its response to bacterial pathogens.

Bobby Cherayil, MD

Research in my laboratory is directed at understanding how immune responses to bacterial infection are influenced by host and environmental factors. Over the last five to six years, my team has been characterizing the interactions between iron homeostasis and the response to infection.

We have made significant contributions to this area, particularly with respect to the effects of the mammalian iron transporter ferroportin on microbial growth and host innate immunity.


Christina S. Faherty, PhD

The main focus of my laboratory centers on the bacterial pathogen Shigella flexneri. This organism creates a significant global health burden each year by causing millions of infections, predominantly in children under the age of five years in developing countries.

Despite more than 50 years of effort, there is still no effective vaccine against this pathogen. While many aspects of the Shigella infection cycle have been investigated, a crucial gap in knowledge remains in the important steps in pathogenesis during early infection.


Alessio Fasano, MD

We are currently investigating the composition and changes in the gastrointestinal microbiota to help determine why some individuals with an inherited predisposition to celiac disease develop clinical disease, while others do not. We are also working to uncover a biomarker and diagnostic tool for non-celiac gluten sensitivity.

We are also investigating the role of the timing of gluten introduction to infants in the development of celiac disease, and working to uncover a biomarker and to develop a diagnostic tool for gluten sensitivity.


Maria Rosaria Fiorentino, PhD

The Fiorentino lab is interested in elucidating the molecular mechanisms of host-microbial interaction and understanding the impact of changes in the gut environment on brain function and behavior.


Verena Gobel, MD

The Gobel laboratory studies polarity, epithelial morphogenesis and growth regulation in Caenorhabditis elegans. One of our objectives is to contribute to the understanding of the molecular basis of intestinal morphogenesis.


Bryan Hurley, PhD

Our overall research objective is to gain a better understanding of how injury, infection, and/or genetics drive mucosal inflammation and damage, manifesting as disease. More specifically, our team explores how bacterial pathogens and other noxious agents impact barrier integrity at the respiratory and digestive surface and elicit inflammatory processes.


Nitya Jain, PhD

The Jain Lab is dedicated to understanding how the immune system develops and operates in newborns, and in identifying the environmental host factors that dictate plasticity in neonatal immune function.


Hongmei Mou, PhD

The Mou Laboratory applies stem cell technologies to investigate personalized medicine approaches for lung and airway diseases including cystic fibrosis, asthma, bronchopulmonary dysplasia (BPD) and chronic obstructive pulmonary disorder (COPD).


Hai Ning Shi, DVM, PhD

Research in the Shi lab is focused on the effects of chronic intestinal helminth infection on concurrent infection with bacterial enteropathogens, the influence of early intestinal colonization with probiotic organisms on subsequent mucosal immune responses, and the effect of maternal gestational factors on the development of allergies in offspring.


W. Allan Walker, MD

The Walker Lab's research efforts include defining the passive and active protective properties of human breast milk with regard to the protection from disease during the newborn period. The lab is also studying the development of human intestinal host defenses using human fetal organ cultures, cell lines, and xenograft transplant models.


Ali R. Zomorrodi, PhD

The Zomorrodi Lab strives to advance precision medicine through developing computational and systems biology approaches. The current focus of the lab is to construct computational mechanistic models of the microbiome and metabolism to better understand the pathogenesis of human diseases and to streamline the design of personalized treatments.
