Andrea Paola Solis-Pazmino, Visiting Scholar

Dr. Paola Solis is a medical doctor born and raised in Ecuador, interested in Otolaryngology, Head and Neck Surgery. She attended medical school at Universidad Central in Quito Ecuador (2019). During her last year of medical school, she had the opportunity to get trained in systematic reviews and meta-analysis at the Knowledge, Evaluation, and Research (KER) Unit – Mayo Clinic. After this training, along with doctors from the USA, Ecuador, Colombia, and Peru she decided to form a group called CaTaLiNA which aims is to generate knowledge around thyroid disease, and to train medical students in clinical and research skills.

She joined Stanford as Research Fellow in September 2019 where she started working on preclinical studies and imaging with shortwave infrared light (SWIR) to improve diagnosis and treatment in cholesteatoma.
