Kotlarz Lab

The mission of our research group is to explore the molecular causes in children with very early onset inflammatory bowel disease (VEO-IBD), a life-threatening condition. In particular, our laboratory focuses on decoding genetic and immune signatures of VEO-IBD by employing omics-based technologies and advanced preclinical models. We propose that our studies will lead to new insights into disease pathogenesis, diagnosis, and treatment for children with this intractable disease.
