Research Focus

Relationship of bacteria, immunology, and inflammation as it pertains to diseases such as inflammatory bowel disease and colon cancer. The laboratory is studying models of bacteria induced intestinal inflammation to uncover key players in development of intestinal inflammation and cancer with the goal of enhancing diagnostic capabilities and treatment.

Research Contributions

Description of a specific bacteria induced intestinal inflammation and colon cancer murine model.

Current investigations include:

The role of innate immune markers and transcription factors in bacteria induced murine colitis.
