Dr. Karin Wu is Assistant Professor of Medicine at UCSF and Staff Physician at the San Francisco VA Health Care System. She is board-certified by the American Board of Internal Medicine in the subspecialty of Endocrinology, Diabetes and Metabolism. Her work centers on improving care for patients with osteoporosis and metabolic bone disease. Her research uses both clinical and translational methods to understand the interactions between nutrition, the gut microbiome, and skeletal health, and to create new approaches for fracture prevention.

The Halkias lab studies the cellular and molecular signals that drive human immune development with a focus on understanding how early life host-microbe interactions influence adaptive immune responses to perinatal inflammatory disorders such as preterm birth. Early life is a critical time in immune development marked by rapid exposure to environmental antigens. Microbial colonization of mucosal tissues plays a key role in the development and education of the host immune system and influences the susceptibility to immune-mediated disease later in life.

I'm a K08 funded physician scientist studying impact of gut microorganisms on human health and applying multi-omic technologies to the study of chronic diseases with clinical focus in pulmonary medicine.

As a pediatric gastroenterologist and physician scientist, I am keenly aware of the challenges faced by our pediatric population. The intestinal epithelium comprises the human body’s greatest environmentally exposed surface and is the largest sensory and endocrine organ. My research utilizes human intestinal organoids and animal models to understand how the intestine senses and responds to both regular and inflammatory stimuli.

The Ahituv lab is focused on identifying gene regulatory elements and linking nucleotide variation within them to various phenotypes including morphological differences between species, drug response and human disease. In addition, our lab is developing massively parallel reporter assays (MPRAs) that allow for high-throughput functional characterization of gene regulatory elements and the use of gene regulatory elements as therapeutic targets or disease diagnostic markers.
