Sosa is an American endocrine surgeon and surgical oncologist, specializing in thyroid cancer.

Her contributions have led to the revision of practice guidelines for the management of patients with endocrine diseases. In August 2025, Dr. Sosa co-chaired the newly published [https://pubmed.ncbi.nlm.nih.gov/40844370/ 2025 American Thyroid Association management guidelines] for adult patients with differentiated thyroid cancer, alongside Dr. Matthew Ringel, of The Ohio State University.
