Research Interests

A recipient of multiple NIH grants, Dr. Olson achieved recognition for his groundbreaking basic science and clinical research on endocrine tumor formation. In particular, his work has led to a greater understanding of how excessive hormone and calcium levels can contribute to tumor development and disease, with a particular focus on how hyperparathyroidism leads to parathyroid neoplasia. His research team reported the first isolation and functional characterization of parathyroid cell subtypes from parathyroid tumors, findings that have enabled the field to hone in on the disease’s development and trajectory. Further, his clinical research has focused on novel endocrine therapies aimed at shrinking breast cancer tumors and determining biomarkers related to breast cancer outcomes.
