Our Faculty

CCHD investigators range from MD, PhD tenured Professors to Assistant Professors (tenure track). Most of the faculty hold secondary (interdisciplinary) appointments in the Departments of Genetics & Development, Microbiology or Nutrition. These appointments link the Department of Medicine with Columbia University graduate programs, thus providing a rich training environment for PhD students. In addition, the CCHD faculty members are principal investigators of NIH-funded T32 training grants in post-graduate Fellowship Programs from various divisions (Pulmonary, Digestive and Liver Disease) or other Departments.

Kelley Yan, MD, PhD
Dorothy L. & Daniel H. Silberberg Assistant Professor, Columbia Center for Human Development and Genetics & Development, Division of Digestive & Liver Diseases

Research Interests:
Our lab investigates the normal physiology of the intestinal epithelium and how it is replenished by intestinal stem cells (ISCs). We have described distinct cell types that normally do not serve as ISCs but can be recruited to regenerate tissue in the setting of injury. We have also shown how extrinsic signals from the stem cell niche regulate the behavior of ISCs during young and health. As a physician-scientist, I aim to understand how these biological processes are perturbed during age and disease with the ultimate goal to develop therapies for treatment of human disease. We use a multi-disciplinary approach that combines single-cell genomics, mouse genetics and organoid platforms.

1. Signals that recruit the normally dormant cell populations within the intestinal epithelium to elicit injury-induced tissue repair.  We aim to understand and enhance tissue repair, not only of the intestine but other tissues more broadly.

2. Effects of aging of the intestinal epithelium, specifically of ISCs and their niche.  We are using an unbiased approach toward understanding how stem cell compartments age and lead to tissue dysfunction.  Our goal is to identify the key drivers of aging in ISCs and to enable their therapeutic manipulation to slow, halt or reverse aging.

3. To understand and manipulate the development of intestinal enteroendocrine cells, which are poorly understood and understudied but nonetheless harbor vast therapeutic potential to treat human metabolic diseases like diabetes and obesity.
