Mission Statement

The Department of Radiology and Biomedical Imaging at Yale University is committed to diversity, equity and inclusion. To promote and sustain an inclusive culture in which differences spur the development of novel solutions to meet the needs of our patients and staff members. Our department aims to foster a culture that values, accepts, and embraces all of its members. We welcome people from all walks of life, value our differences, and celebrate our similarities. We work to achieve that every member of our community feels valued and inspired to excel in patient care, research, education, and well-being.

Aspirational Objectives

  • Over the coming year, a Radiology diversity committee and department leadership will work to strengthen our cultural competency by launching diversity education and culture sharing sessions.
  • Continue to diversify our department by recruiting and retaining a diverse faculty and by being purposeful about diversity and inclusion during the trainee recruitment process.
  • To strengthen the department's sense of community by organizing a community activity that includes representatives from each departmental section, trainee group, and staff group, so that everyone feels valued, engaged, and supported.

Commitee Roster

  • Associate Professor of Radiology and Biomedical Imaging; Vice Chair for Diversity, Equity and Inclusion, Radiology & Biomedical Imaging; Medical Director of Vascular and Interventional Radiology at Park Avenue Medical Center, Radiology & Biomedical Imaging

    Juan Carlos Perez Lozada, MD, is an interventional radiologist who says he enjoys the minimally invasive aspect of his work that allows patients to recover rapidly.“The extensive variety of pathology each day makes this field my passion,” Dr. Perez Lozada says. “My favorite part of interventional radiology is the scope and breadth of clinical conditions and procedures that I can treat and the constant innovation of my field. I love that I still am able to guide and counsel patients in clinic and be part of their treatment team.” He says he always lets his patients know that their well-being is his priority. “I want them to be safe regardless of the procedure. I want the best treatment possible regardless of the specialty that will take care of them,” he says. “The best patient is the one that has knowledge of their options.” Dr. Perez Lozada offers uterine fibroid embolization, spine interventions, pain management and nerve blocks, dialysis interventions, management of deep venous thrombosis and pulmonary embolism, and interventional oncology.
  • Professor of Radiology and Biomedical Imaging and of Biomedical Engineering; Technical Director, Magnetic Resonance Research Center (; Program Director, Core Center for Quantitative Neuroscience with Magnetic Resonance (

    Dr. Hyder is Professor of Radiology & Biomedical Imaging and Professor of Biomedical Engineering, where he is a founding faculty member. He is Head of MRS Group of the MRRC and Director of QNMR Research Program. He studied physical chemistry at Wabash College (BA 1990) and biophysical chemistry at Yale University (PhD 1995). Dr. Hyder studies brain energy metabolism. His lab develops magnetic resonance (MR) based imaging methods to study brain physiology and chemistry, revealing how neuronal-glial cells fuel their function and (re)growth. He posits that mapping metabolic dysfunction (e.g., energetics for cellular function vs. cellular proliferation) can indicate early biomarkers of brain disorders and diseases. To map brain’s physiology and chemistry with MR-based imaging and spectroscopic advances and targeted delivery and monitoring of treatments, his laboratory conducts multidisciplinary functional and molecular imaging of neurodegeneration and neuro-oncology, requiring expertise in physics to chemistry to engineering to cancer biology to neuroscience. His contributions include development of high-resolution fMRI in preclinical models, calibrated fMRI for quantitative imaging of neuronal activity, and molecular imaging methods for pH and temperature mapping and other physiological parameters that are relevant in cancer diagnosis and treatment. Dr. Hyder has written and edited books on functional brain imaging and holds several patents on molecular imaging of cancer. His research work has produced over 240 papers with as many invited presentations, amassing over 20K citations. He has had continuous NIH support for 25 years, spanning across interests from 7 different NIH institutes. He has renewed grants from different funding agencies and has received several early career awards from. He sits on editorial boards of several scientific journals, and he reviews for many scientific journals spanning several disciplines. He serves on advisory panels of several funding agencies. Dr. Hyder holds many honors, including the Melvin H. Knisely Award from the International Society on Oxygen Transport to Tissue, the Niels Lassen Award from the International Society for Cerebral Blood Flow and Metabolism, and the Lundbeck Foundation Visiting Professorship at the University of Copenhagen. He has fellowships in American Institute for Medical and Biological Engineering, Academy of Radiology & Biomedical Imaging Research, and Sigma Xi the Scientific Research Honor Society. Recently, he was appointed Head of Trumbull College at Yale University and received a General Assembly Official Citation from the State of Connecticut.
  • Professor of Radiology and Biomedical Imaging and of Psychiatry; Director Metabolic Modeling and Director Psychiatric MRS, Magnetic Resonance Research Center; Director, Neuroimaging Sciences Training Program, Radiology & Biomedical Imaging and Psychiatry; Chair, Magnetic Resonance Research Center Protocol Review Committee, Radiology & Biomedical Imaging

    Dr. Graeme F. Mason develops experimental models and methods for studies of brain metabolism using 1H and 13C Nuclear Magnetic Resonance (NMR) and Mass Spectrometry in conjunction with 13C isotopic labeling in vivo, in cell preparations, and other systems. His work began during his graduate studies at Yale where he used a rat model for the experimental determination of brain glucose transport kinetics, energetics, and neurotransmitter metabolism. Dr. Mason received further training at the University of Alabama at Birmingham, where he guided the group's 13C-labeling studies of the human brain in vivo in the 4.1T whole-body MR system. Dr. Mason studies metabolism and neurotransmission in the brain in vivo, including effects of psychiatric, neurological, and metabolic conditions. Dr. Mason examines healthy subjects and patients to investigate relationships among GABA, glutamate, and glutamine concentrations and their rates of synthesis and release in the brain, in particular with regard to effects of acute and chronic use of alcohol. He also studies detailed kinetic modeling of isotopomer and isotopologues using data from high-resolution NMR and mass spectrometry.
