Dr. Christin Sander’s research focuses on multi-modal functional brain imaging with combined MRI (magnetic resonance imaging) and PET (positron emission tomography). Her main interests include (i) dynamic imaging of dopamine & glutamate neuroreceptor function through pharmacology and neuromodulation, (ii) advance multi-modal imaging techniques and translational experimental approaches and (iii) devise quantitative models of imaging signals. Her overall goal is to map molecular signaling pathways of the living brain to advance our understanding of brain disorders in psychiatry and drug addiction.

Changning Wang, PhD, has a unique and broad background in molecular imaging, medicinal chemistry, pharmaceutical sciences and neuroscience. After finishing his doctoral studies, he joined Martinos Center for Biomedical Imaging as a research fellow and later as a trainee in the Harvard/MGH Nuclear Medicine Training Program, to expand his research skills in clinical imaging research. He is now an assistant professor at Harvard Medical School. In the past few years, he has developed [11C]Martinostat as a robustly brain penetrant imaging agent with selectivity for class I HDACs. [11C]Martinostat is the first and only-to-date PET imaging probe for epigenetic research. He designed this probe in only a half year, an extremely short time. The exploratory IND for [11C]Martinostat was approved by the FDA for first-in-human trials and is the first tool of its kind available to characterize HDAC expression in the living human brain. Dr. Wang is leading the project of [11C]Martinostat clinical imaging in several patient groups. He is also working on developing new PET imaging probes targeting other epigenetic enzymes and using these tools for new drug discovery.

Dr. Wang played a major role in the development of the first epigenetic PET imaging probe, [11C]Martinostat, at the Martinos Center for Biomedical Imaging. The exploratory Investigational New Drug (eIND) for [11C]Martinostat was approved by the FDA in late July 2014 for first-in-human trials (IND # 123154). Currently, [11C]Martinostat is being used in multiple IRB-approved clinical research studies at MGH in patients with Huntington disease, Alzheimer’s disease, Schizophrenia, alcohol use disorder and multiple sclerosis.

Abbas Yaseen, PhD, is an Assistant Professor of Radiology at Harvard Medical School specializing in advanced microscopy for minimally invasive, in vivo characterization of brain function in preclinical models. His group focuses on the development and application of high-resolution optical imaging technologies for investigating metabolic and immune characteristics of brain function and disease-related alterations. The overarching goal of these efforts is to characterize the etiologies of cerebral pathologies such as stroke and neurodegenerative disorders with cellular resolution to yield robust biomarkers for diagnosis and therapy.

Dr. Clavijo Jordan’s interests include the use of molecular MR imaging to detect and characterize inflammation, fibrosis and cancer. She is particularly interested in understanding the role metals play in the development of disease. Recently, she and colleagues have been using molecular MRI probes that detect metals such as Zn and Cu. By stimulating the natural secretion mechanisms in secretory organs in vivo, it is possible to initiate the natural flux of these metals in organs including the pancreas, both endocrine and exocrine, and the prostate. This stimulatory paradigm allows researchers to interrogate the physiological metal flux, as well as its content. Recently, Dr. Clavijo Jordan and colleagues showed that a dysregulated zinc flux and loss of content can be detected with MRI in the prostate in models of prostate cancer. Using fibrosis, inflammation and metal-specific molecular probes, they intend to obtain a holistic view of disease with MRI.
