Research Summary

Dr. Johnson received a Bachelor of Science degree in microbiology with Highest Honors at the University of Iowa and then completed her medical education and doctorate in immunology at Washington University School of Medicine in St. Louis. After her research on the molecular pathways immune cells use to fight cancer, Dr. Johnson decided to focus on patients with a high risk of developing skin cancer. Following an internship in internal medicine in Boston and training in dermatology at the New York University School of Medicine, she completed a two-year fellowship in Mohs micrographic surgery and procedural dermatology at the Columbia University School of Physicians and Surgeons/New York-Presbyterian Hospital. While in training, she initiated one of the first research projects assessing patient safety and quality of care in the field of dermatology. Dr. Johnson’s collective research interests in cutaneous oncology, surgical reconstruction, and patient safety continue to grow. She is a published author of several peer-reviewed journal articles and book chapters, and is a frequent lecturer at universities and national meetings of multiple medical specialty associations.
