Maxime M. Mahe, PhD

  • Adjunct Assistant Professor, UC Department of Surgery



Prior to joining Cincinnati Children's Hospital Medical Center, Dr. Mahe performed his PhD research at the National Institute of Health and Medical Research in the Division of Neuropathies of the Enteric Nervous System and Digestive Diseases, in Nantes, France. His work emphasizes on understanding interactions between the enteric nervous system and intestinal epithelial cells.

In 2012, Dr. Mahe moved to Cincinnati Children's Hospital Medical Center to focus on the study of intestinal stem cells in the laboratory of Dr. Michael Helmrath. Since, he has been involved in collaborative studies aiming at understanding stem cell fate and gastrointestinal epithelial biology including the generation of functional human small intestine.

In 2015, Dr. Mahe became an instructor in the Division of Pediatric General and Thoracic Surgery at Cincinnati Children's within the UC Department of Pediatrics. In 2017, he was recruited as an assistant professor at Inserm, France to establish a research program on the effects of the enteric nervous system on intestinal development using innovative approaches. Dr. Mahe is currently an adjunct assistant professor in the Division of Pediatric General and Thoracic Surgery at Cincinnati Children's Hospital Medical Center.
