Dr. David J. Perry

Russell Hales, M.D., is an assistant professor of radiation oncology and molecular radiation sciences at the Johns Hopkins University School of Medicine. He also is director of the thoracic multidisciplinary clinic. His research focuses on reconstructing health delivery models to enhance value and improve clinical outcomes. He also studies the effect of immunotherapy and RT in thoracic tumors. Dr. Hales was awarded an R21 grant to study the use of dynamic MRI in predicting tumor motion in patient with lung cancer. Taken together, his research focuses on optimizing patient outcomes using resources from physics, engineering, biology and health delivery systems. Dr. Hales’ efforts extend beyond radiation oncology and clinical management. He has helped to lead in the thoracic oncology program, which includes 20 faculty members and nearly 50 staff, to help chart a vision for this program’s future. In the last four years, the program has gradually transitioned from The Johns Hopkins Hospital campus to Johns Hopkins Bayview Medical Center. Dr. Hales was tasked to head the building and design committee that worked with architects to create a structure conducive to 21st century oncology care. His work extends beyond the bricks and mortar of the new cancer center today to team development within the thoracic oncology program. Simply put, the thoracic oncology move was designed to conceptualize the transition of care from department-based to disease-based medicine. As such, Dr. Hales has worked to integrate the efforts of specialists in medical oncology, thoracic surgery, interventional pulmonology, pathology and radiology. These experts share a clinical space focused on thoracic malignancies and bring a patient-centered model of care to their group. Dr. Hales graduated from Brigham Young University Summa Cum Laude and Valedictorian in 2001. He attended Johns Hopkins Medicine and graduated with an M.D. in 2005. He trained on the Osler Medical Service and attended residency at Johns Hopkins. He joined the faculty at Hopkins in 2010. Dr. Hales focus in program building, research and clinical endeavors is robust, but he understands the key role of academia in training future leaders in medicine. He has been awarded Teacher of the Year in the department of radiation oncology at Hopkins for three of the last six years. He is a well-respected lecturer and travels nationally to speak at conferences and educational workshops about novel therapies in lung and esophagus cancer. Make A Gift. Dr. Hales is rated as a Distinguished provider by MediFind in the treatment of Small Cell Lung Cancer (SCLC). His top areas of expertise are Lung Cancer, Small Cell Lung Cancer (SCLC), Thymic Epithelial Tumor, Non-Small Cell Lung Cancer (NSCLC), and Endoscopy.

Dr. K. Ranh Voong specializes in thoracic malignancies, including lung, esophageal, thymic cancers, and mesothelioma. She treats patients at both the Johns Hopkins Thoracic Center of Excellence at Johns Hopkins Bayview and at the Proton Center at Sibley Memorial Hospital. She has extensive expertise in proton therapy, SBRT, IMRT for tumors involving the chest. She is the Principal Investigator on grants from Lung Cancer Research Foundation and Hopkins-Wellspan. She is the Principal Investigator of a prospective study evaluating the immunogenic effects of SABR alone on systemic T cell response in patients with stage I NSCLC. She is the principal investigator of a multi-institutional prospective trial showing that routine review of patient-reported outcome measures informs radiation on-treatment toxicity burden assessment and care delivery. She was the Quality of Life Co-chair of a Phase III Randomized Trial of Pleurectomy/Decortication Plus Chemotherapy With or Without Adjuvant Hemithoracic Intensity-Modulated Pleural Radiation Therapy (IMPRINT) For Malignant Pleural Mesothelioma (NRG-LU006). She has been invited to participate in national and regularly lectures on thoracic malignancies and protons for thoracic malignancies therapy. In her research, Dr. Voong is dedicated to improving the outcomes of patients with thoracic malignancies, by exploring avenues to better understand and optimize the delivery of radiotherapy. Dr. Voong is also the Program Director for the Radiation Oncology Residency Program. She mentors residents, medical students. Make A Gift. Dr. Voong is rated as a Distinguished provider by MediFind in the treatment of Small Cell Lung Cancer (SCLC). Her top areas of expertise are Lung Cancer, Pleuropulmonary Blastoma, Small Cell Lung Cancer (SCLC), and Non-Small Cell Lung Cancer (NSCLC).
