Research

Our studies leverage complementary research designs – birth cohorts, cross sectional and longitudinal studies, founder populations, and experimental approaches through the UChicago Asthma Genomics Center – each offering unique advantages for understanding the genetic and epigenetic underpinnings of asthma and allergic disease.
