Asthma and allergic diseases are a serious public health burden and affect over 40% of the population worldwide. In the Division of Asthma Research our overarching goal is to develop new prevention and treatment strategies for allergic diseases that are personalized and target high risk populations at the critical time periods when they are most vulnerable.

In the Division of Asthma Research we are focused on understanding the total exposure relevant to asthma from the cell and individual level to the patient, family neighborhood and community level. We aim to identify the factors that contribute to asthma development and symptoms, determine the mechanisms by which these factors contribute to disease, delineate how effects of environmental exposure are modified by genetics and other exposures, and identify biomarkers of exposure and disease activity and severity in an individual. Our current projects include a spectrum of basic, translational and clinical research that investigates the role of these factor in promoting disease development and activity.
The division utilizes transdisciplinary approaches integrating human cohorts, in vitro systems, and animal models to address these complex problems. Numerous other factors affect disease outcomes as well including psychosocial factors, community health perceptions, and health literacy.

Induced pluripotent stem cells (iPSCs) hold tremendous potential, both as a biological tool to uncover the pathophysiology of disease by creating relevant human cell models and as a source of cells for cell-based therapeutic applications. In this study we sought to characterize the derivation of iPSC lines from nasal epithelial cells (NECs) isolated from nasal mucosa samples of children.
