Dr. Niesvizky is Professor of Medicine at Weill Cornell Medical College and at NewYork Presbyterian Hospital/Weill Cornell Medical Center in Manhattan. He also serves as Director of the Multiple Myeloma Center at NewYork Presbyterian Hospital/Weill Cornell Medical Center. After receiving a medical degree from National University of Mexico, Dr. Niesvizky did a research fellowship in cell biology-granulocytopoiesis and an internal medicine residency at the National Institute of Nutrition in Mexico. He then completed fellowships in New York: one (hematology) at Mount Sinai Medical Center and one (hematology/medical oncology) at Memorial Sloan-Kettering Cancer Center. He has written more than 100 articles, editorials, chapters, and abstracts published in journals such as New England Journal of Medicine, Blood and Leukemia & Lymphoma, most recently on topics such as the treatment of myeloma and Waldenstrom's macroglobulinemia. He is the recipient of various grants and awards from the National Cancer Institute and the Leukemia and Lymphoma Society, including a K23 award and three translational research grants. He received the 2007 Investigator Award of the Michael Wolk Heart Foundation. He has been voted by pears as “Best Doctors” in 2013 and appeared in New York Magazine as Hematolgy “Top Doctors” 2014. A frequent lecturer, Dr Niesvizky regularly presents at annual meetings of the American Society of Hematology and the American Society of Clinical Oncology, of which he is also a member. He is an active member of the International Myeloma Working Group which defines standards of research and practice in myeloma. He is an active participant in clinical trials of promising new drugs and medical procedures for the treatment of myeloma, lymphoma, and related hematologic disorders.

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.
