Dr. Mateo Mejia is an Assistant Professor of Medicine in the Division of Hematology and Medical Oncology at Weill Cornell Medicine and an Assistant Attending Physician at NewYork-Presbyterian Hospital.Dr. Mejia received his medical degree (M.D.) from the Universidad CES in his hometown of Medellin, Colombia, after which he completed an internal medicine residency at the Jacobi Medical Center/Albert Einstein College of Medicine in the Bronx, NY, where he also served as a Chief Resident. He completed his Hematology and Oncology fellowship at Weill Cornell Medicine/NewYork-Presbyterian Hospital and joined the Hematology and Medical Oncology Division after completing his fellowship training in 2023. During fellowship, Dr. Mejia developed his clinical experience under the mentorship of Dr. Ruben Niesvizky, while pursuing his laboratory research at Dr. Mark Bustoros’ Laboratory, being able to complete both clinical and translational research in the plasma cell malignancy field.Dr. Mejia’s research has focused on the genomic drivers of aggressive forms of myeloma, for which he received the 2022 Conquer Cancer – American Society of Clinical Oncology (ASCO) Young Investigator Award, a prestigious honor only given to 100 of people each year. Additionally, Dr. Mejia was the recipient ofthe 2022 Charles, Lillian and Betty Neuwirth Foundation Fellowship in Oncology award for his project “Genomic Landscape of Multiple Myeloma with Extramedullary Disease”. Dr. Mejia’s research also investigates the connectionof race, ethnicity and myeloma, how myeloma escapes the surveillance of the immune system, as well as how genetic information can be used to develop novel approaches to treat myeloma.
