Dr. Stiemsma has expertise in microbiology, microbial ecology, and the role of the human microbiome in non-communicable diseases. Her PhD dissertation focused on the role of the intestinal microbiome in childhood asthma and atopic disease. As a postdoctoral fellow at UCLA, she studied microbiome-diet interactions and worked to integrate the microbiome into human cohort studies. Dr. Stiemsma has taught workshops and guest lectured on the microbiome and its association with immune-mediated and atopic diseases at UCLA and the University of Freiburg, Germany. Her current research focus is on the human mammary tissue microbiome and its potential to serve as a biomarker for breast cancer.
