Stephen D. Nimer, M.D.

Director of the Sylvester Comprehensive Cancer Center, Executive Dean for Research and Professor of Medicine, Biochemistry and Molecular Biology

Stephen D. Nimer, M.D., has been studying the transcriptional regulation of normal and malignant hematopoiesis for decades, with the aim of understanding how the normal processes of stem cell self-renewal and differentiation are regulated and how these processes are aberrant in myeloid malignancies. Overall, his lab has focused on defining genes that contribute to the development and progression of myelodysplastic syndromes (MDS) and acute myelogenous leukemia (AML) and on identifying novel ways to target hematologic cancers and make them more responsive to treatment.

As a physician-scientist, Dr. Nimer has cared for patients with MDS, AML, multiple myeloma and lymphoma for over three decades. This melding of clinical studies and care, with both basic laboratory and translational studies, reflects the fundamental focus of his career.

Since coming to the University of Miami-Miller School of Medicine in 2012 and assuming the Directorship of Sylvester Comprehensive Cancer Center, the center received the prestigious National Cancer Institute designation in July 2019. Sylvester is the only cancer center in South Florida to achieve this designation and the second in the state of Florida. Dr. Nimer is currently supported by two NCI R01 grants and a Leukemia and Lymphoma Society (LLS) multi-project Specialized Center of Research (SCOR) award. In November 2019, Dr. Nimer was named the inaugural Oscar de la Renta Endowed Chair in Cancer Research. In November 2021, Dr. Nimer assumed the role of Executive Dean for Research for the Miller School of Medicine, and in May 2022, he assumed a secondary appointment as Professor of Chemical, Environmental & Materials Engineering.

Prior to his arrival at the University of Miami-Miller School of Medicine, Dr. Nimer was at Memorial Sloan-Kettering Cancer Center in New York for nearly 20 years, where he held the Alfred P. Sloan Chair and served as Head of the Division of Hematologic Oncology, Vice Chairman for Faculty Development, and Chief of the Hematology Service. He was also a Professor of Medicine and Pharmacology at Weill Medical College of Cornell University.

Dr. Nimer has been elected to the American Society of Clinical Investigators and the Association of American Physicians. He is a Fellow of the American College of Physicians and serves on the editorial board of several medical journals. In April 2021, Dr. Nimer was inducted into the Academy of Science, Engineering, and Medicine of Florida. Dr. Nimer is also the Chairman of the Myelodysplastic Syndrome Foundation and the Chairman of the Medical Advisory Board of Gabrielle’s Angel Foundation for Cancer Research.

Mayo Clinic Comprehensive Cancer Center

Roxana S. Dronca, M.D.

Site Director, Mayo Clinic Comprehensive Cancer Center in Florida

Roxana Dronca, M.D., serves as site director of Mayo Clinic Comprehensive Cancer Center in Florida. She is also a distinguished professor of oncology and a consultant in, and chair of, the Division of Hematology/Oncology at Mayo Clinic in Florida. With over 15 years of experience as a practicing medical oncologist at Mayo Clinic, Dr. Dronca specializes in advanced skin cancers and genitourinary malignancies.

Her extensive background encompasses hematology-oncology, clinical and translational research, with a focus on investigator-initiated studies and multi-institutional clinical trials for patients with advanced malignancies. Dr. Dronca’s primary research interests lie in tumor immunology, cutaneous melanoma and rare melanoma subtypes. She is dedicated to unraveling the intricate interactions between the immune system and cancer, studying systemic immune regulation in patients with advanced malignancies, and pioneering innovative approaches to cancer therapy through individualized immunotherapy.

A key area of Dr. Dronca’s research involves the PD-1/PD-L1 signaling pathway and its implications in impaired host immunity in advanced cancer patients. Collaborating closely with Dr. Haidong Dong, co-discoverer of PD-L1, and other Mayo Clinic researchers, she explores T-cell responses to anti-PD-1 therapy in melanoma patients, investigates mechanisms of clinical activity and resistance to immunotherapeutic agents, and develops rational approaches to overcome resistance in human cancers.

In the earlier phase of her career, Dr. Dronca served as the Mayo Clinic principal investigator on phase I and phase II clinical trials with the anti-PD-1 agent Pembrolizumab, contributing significantly to its FDA approval for treating patients with advanced melanoma. Her work has been published in prestigious journals such as the New England Journal of Medicine, Lancet, JAMA, Journal of Clinical Oncology, Annals of Oncology, and the Journal of Clinical Investigation Insight. Furthermore, she secured an R21 grant in 2015.

In recent years, Dr. Dronca has expanded her contributions to cancer care delivery research and implementation science. Co-leading institutional efforts, she played a pivotal role in envisioning and establishing the Mayo Clinic Cancer CARE (Connected Access and Remote Expertise) Beyond Walls Program. This platform-enabled solution aims to revolutionize cancer care delivery by providing therapy, supportive services, ancillary testing, and remote monitoring within a patient’s home, bridging the gap between traditional healthcare settings and modern telehealth technologies. As the leader of Cancer services at Mayo Clinic in Florida, Dr. Dronca laid the foundation for this innovative initiative and serves as the Enterprise and Cancer Center physician lead, demonstrating her commitment to creating a patient-centric model of cancer care that integrates digital technologies with traditional therapeutic approaches.
