About Neural Gut Axis group

The Neural Gut Axis group is a team of faculty at Texas A&M University in the Department of Neuroscience and Experimental Therapeutics (NExT), working together toward understanding the bi-directional relationship between the nervous system and the gut. They are organizing a scientific symposium on neuroscience and the gut to bring together researchers from various fields and provide a platform for interactive discussions and the exchange of ideas.

Dr. Farida Sohrabji

Dr. Farida Sohrabji is Regents Professor and Department Head of Neuroscience and Experimental Therapeutics. Her research focuses on the acute and chronic consequences of ischemic stroke, which is a leading risk factor for AD and related dementias. Recent work concentrates on the role of the gut microbiome, gut metabolites and gut permeability after stroke, and supports the idea that “Gut health is brain health”


Dr. Michelle Hook

Dr. Michelle Hook is an Associate Professor in the Department of Neuroscience and Experimental Therapeutics at Texas A&M University. Her research focuses on recovery of function following spinal cord injury (SCI), and the role of the gut in the  development of depression and cognitive impairment after SCI.


Dr. Lee Shapiro

Dr. Lee Shapiro is an Associate Professor in the NExT Department. His research concentrates on Traumatic Brain Injury and its consequences on gut health. One goal is to target the Neural-Gut Axis to promote recovery after TBI.


Dr. Cédric Geoffroy

Dr. Cedric Geoffroy is an Assistant Professor in the Department of Neuroscience and Experimental Therapeutics at Texas A&M University. Texas A&M University. His research focuses on understanding how the changes in the gut microbiota and metabolites after SCI negatively impact health (including cardiometabolic functions, bowel functions, and locomotion).

Other members of the NGA group


Dr. Karienn Souza

Dr. Karienn Souza is a Research Assistant Professor and Director of the NExT Behavioral Core at the Texas A&M College of Medicine.
The overarching goal of her research program is to the determine how alterations of the gut-brain axis contribute to the development of cognitive and circadian dysfunction in advanced age.


Dr. David Earnest

Dr. David Earnest is a Professor in the NExT department. His current research focuses on understanding the interplay between circadian disruption, gut functions and neural injury.  


Dr. Rajesh Miranda

Dr. Rajesh Miranda is a Professor in the NExT Department. One aspect of his research is to determine whether prenatal alcohol exposure produces changes in gut function, and subsequently impacts neural development and long-term health.
