Neuromodulation and Advanced Therapies Center
We investigate the brain networks and neurotransmitters involved in symptoms of movement disord...ers, such as Parkinson's disease, and the mechanisms by which modulating these networks through electrical stimulation affects these symptoms. We are particularly interested in the mechanisms through which neuromodulation therapies like deep brain stimulation affect non-motor brain functions, such as cognitive function and mood. We use imaging of specific neurotransmitters, such as acetylcholine and dopamine, to understand the changes in brain chemistry associated with the clinical effects of deep brain stimulation and to predict which patients are likely to have changes in non-motor symptoms following DBS. Through collaborations with our neurosurgery colleagues, we explore brain function by making recordings during DBS surgery during motor and non-motor tasks. Dr. Mills collaborates with researchers in the Department of Neurosurgery, the Division of Geriatric and Neuropsychiatry in the Department of Psychiatry and Behavioral Sciences and in the Division of Nuclear Medicine within the Department of Radiology to translate neuroimaging and neurophysiology findings into clinical applications. view more

The Pathak Lab
Lab WebsiteThe Pathak lab is within the Division of Cancer Imaging Research in the Department of Radiology... and Radiological Science. We develop novel imaging methods, computational models and visualization tools to ‘make visible’ critical aspects of cancer, stroke and neurobiology. Our research broadly encompasses the following areas: Functional and Molecular Imaging; Clinical Biomarker Development; Image-based Systems Biology and Visualization and Computational Tools. We are dedicated to mentoring the next generation of imagers, biomedical engineers and visualizers. Additional information can be found at www.pathaklab.org or by emailing Dr. Pathak. view more

Venu Raman Research Lab
The Raman laboratory is within the Division of Cancer Imaging Research in the Department of Rad...iology and Radiological Science. The focus of the laboratory is bench-to-bed side cancer research. We integrate molecular and cellular biology, developmental biology, cancer biology, molecular imaging techniques to study cancer formation and progression. Many of the projects in the lab investigate dysregulated genes in cancer and the translatability of this information to a clinical setting. One such project is to functionally decipher the role of a RNA helicase gene, DDX3, in the biogenesis of multiple cancer types such as breast, lung, brain, sarcoma, colorectal and prostate. Additionally, using a rational drug design approach, a small molecule inhibitor of DDX3 (RK-33) was synthesized and its potential for clinical translation is being investigated. view more

Weiss Lab
Lab WebsiteThe Weiss Lab, which features a multi-disciplinary team at Johns Hopkins as well as at Cedars S...inai Medical Center in Los Angeles, is dedicated to identifying the most important clinical, genetic, structural, contractile and metabolic causes of sudden cardiac death as well as the means to reverse the underlying pathology and lower risk.
Research Areas: energy metabolism, creatine kinase metabolism, imaging, heart failure, aging, cardiology, sudden cardiac death
Current projects include research into energy metabolism in human heart failure and creatine kinase metabolism in animal models of heart failure.
Robert G. Weiss, MD, is professor of medicine, Radiology and Radiological Science, at the Johns Hopkins University. view more
