Dr. Anastasia Yendiki’s background is in statistical signal and image processing. She received a PhD in Electrical Engineering: Systems from the University of Michigan at Ann Arbor, where she worked on inverse problems in tomographic reconstruction for nuclear imaging under the supervision of Jeff Fessler. As a postdoctoral research fellow at the Athinoula A. Martinos Center for Biomedigal Imaging, Harvard Medical School and Massachusetts General Hospital, she trained in functional and diffusion-weighted MRI. She received an NIH K99/R00 Pathway to Independence award, which led to the development of TRACULA, the diffusion-weighted MRI analysis stream in FreeSurfer, under the supervision of Bruce Fischl. She is now on the faculty at the Martinos Center and a member of the Laboratory for Computational Neuroimaging (LCN), continuing to develop publicly available, open-source algorithms for studying white-matter anatomy in health and disease.

Caterina Mainero, MD, PhD, is an Associate Professor of Radiology at Harvard Medical School, Assistant in Neuroscience at Massachusetts General Hospital and Director of Multiple Sclerosis Research at the Athinoula A. Martinos Center for Biomedical Imaging.

Dr. Mainero is a neuroscientist with a background in clinical neurology, specializing in the translation of novel multimodal imaging techniques for investigating structure, function and pathology within the brain and spinal cord of different neurological conditions, with a particular emphasis on multiple sclerosis and migraine.

The Multiple Sclerosis Imaging Laboratory that Dr. Mainero directs at the Martinos Center focuses on using advanced imaging modalities to investigate the heterogenous aspects of multiple sclerosis pathology that include neuroinflammation, demyelination, neurodegeneration, and tissue repair. The goal is to integrate novel imaging methods with clinical and biological markers of the disease to investigate the brain mechanisms underlying disease activity and progression, and to define the most sensitive neuroimaging tools for improving disease diagnosis and monitoring.

Dr. Mainero’s group was the first to image and characterize in vivo, using ultra high field 7 Tesla MRI, the different types of cortical multiple sclerosis lesions described by neuropathology, and to show that the cortical lesion load assessed at 7 Tesla is an independent and main predictor of disease progression. For her pioneering work on imaging cortical lesions in MS, Dr. Mainero has been awarded the “2020 Distinguished Investigator Award” from the Academy for Radiology and Biomedical Imaging Research.

Dr. Matt Rosen is a physicist, tool-builder and inventor whose research bridges the spectrum from fundamental physics to applied bioimaging work in the field of MRI. He established the Low-Field MRI and Hyperpolarized Media Laboratory at the Athinoula A. Martinos Center for Biomedical Imaging to focus on the continued development of new hyperpolarization methods and MRI-based tools.

The Rosen Lab focuses on new methods and tools to enable unconventional approaches to MRI scanner construction. This includes the development of new acquisition strategies for robust ultra-low magnetic field implementations of MRI focused on brain imaging. The laboratory also explores opportunities provided by hyperpolarization including in vivo Overhauser DNP, SABRE and spin-exchange optical pumping. The lab creates new quantitative strategies for the acquisition and the reconstruction of highly undersampled imaging data including neural network deep learning-based approaches such as AUTOMAP that leverage low-cost scalable-compute. Dr. Rosen co-directs the Center for Machine Learning at the Martinos Center.

Dr. Holt has studied the neural basis of psychosis throughout her career, initially in post-mortem samples and subsequently (since 2002) using neuroimaging. Using functional neuroimaging in combination with physiology, behavioral tasks and clinical assessments, she has investigated the neurocognitive basis of the core symptoms of psychotic illness, including delusions, negative affect and social impairment, reporting some of the first evidence for abnormalities in basic mechanisms that underlie emotional perception (e.g. fear extinction memory, fear generalization, response to perceptual threat) in psychotic illness.

Recently Dr. Holt’s group has also focused on identifying changes in brain function and behavior linked with risk for serious mental illness and has been developing novel interventions aimed at increasing resilience and potentially preventing serious mental illnesses in at-risk youth. Dr. Holt also serves as Co-Director of the MGH Schizophrenia Clinical and Research Program, which includes a First-Episode and Early Psychosis Program (FEPP) focused on comprehensive treatment of psychosis in the earliest phases of illness.

Zdravka Medarova, PhD, is an Associate Professor of Radiology at Harvard Medical School. She is a geneticist/cancer biologist by training and has an extensive background in molecular biology, genetics, and tumor biology and therapy. The focus of her research has been the development and testing of multi-functional imaging/delivery vehicles for combined cancer imaging and therapy. Dr. Medarova’s earliest work described, for the first time, the design and application of ultrasmall iron oxide nanoparticles as imaging-capable carriers of siRNA to tumors. This work generated substantial interest in the research community, since it illustrated the value of these nanoparticles for the delivery of small RNA therapy to challenging organ targets and also described an approach for the noninvasive monitoring of small RNA delivery. More recently, her lab developed magnetic nanoparticles as delivery vehicles of miRNA-targeted therapy to metastases. This work resulted in multiple publications in high-impact journals such as Cancer Research, Nature Medicine, Oncogene, and Scientific Reports, as well as grants from private foundations and the NIH.

Dr. Medarova obtained a BA degree in pre-medicine from the University of Southern Maine (1998) and a PhD in Genetics from the University of New Hampshire (2002).

Chongzhao Ran, PhD, is an Associate Professor in Radiology at Massachusetts General Hospital and Harvard Medical School. He received a Master’s degree in medicinal chemistry from China Pharmaceutical University and a PhD in medicinal chemistry from Shanghai Institute of Pharmaceutical Industry, China. He did his postdoctoral training at the University of Chicago and Harvard Medical School. Dr. Ran’s research focuses on the development of molecular imaging probe and imaging technologies. He has published nearly 60 papers in the fields of chemistry and molecular imaging, some in high-ranking journals such as PNAS and J. Amer. Chem. Soc. Since 2010, his research has been continuously supported by multiple NIH grants from NIA, NIDDK and other foundations. In recent years, his research group has successfully developed numerous near-infrared fluorescence (NIRF) imaging probes, which revolve around their own brand CRANAD-X, for in vivo detection of amyloid beta in mouse models of Alzheimer’s disease (AD). Particularly, his research has been focusing on seeking “smart” NIR probes for soluble amyloid beta species, which are widely believed to be the most neurotoxic species at the early stage of AD. Recently, his research group has successfully designed and synthesized secnd-generation PET tracers for amyloid beta species. In addition, his group has discovered several NIRF probes and PET tracers for imaging brown adipose tissue. These probes have remarkable potential for future diagnosis and monitoring the efficacy of drugs for Alzheimer’s disease, diabetes and obesity in preclinical studies and clinical trials.
