My research is focused on elucidating the mechanisms of network-level brain responses to non-invasive brain stimulation methods. Based on the development of the “RF-EEG Cap”, the first-of-its-kind wearable RF head coil and the related signal processing tools, I envision a complete solution for concurrent TMS/fMRI/EEG. This triple combination can be seen as a versatile neuroscience tool which will have the potential to perform non-invasive high-resolution causal mapping of human brain. Using this approach, we will build the unique capability to study the brain in ways that were never before possible, and to revolutionize our understanding of human behavior and cognition.

Dr. Wang is an Assistant Professor of Radiology at Massachusetts General Hospital (MGH) and Harvard Medical School (HMS). She obtained her PhD degree from MIT in the Harvard-MIT Health Sciences and Technology department, receiving interdisciplinary training in electrical engineering, medical physics, neuroscience, and clinical science (completed the pre-clinical curriculum at HMS). Following the completion of her PhD, Dr. Wang joined the faculty of MGH and Harvard Medical School, and has been working in the A. A. Martinos Center for Biomedical Imaging.

Dr. Wang’s research centers on developing novel MRI acquisition and reconstruction techniques to provide higher imaging sensitivity, specificity, and efficiency. Dr. Wang has led the development of a number of imaging technologies that effectively address long-standing challenges of MRI, and successfully demonstrated their value in a wide range of applications, such as functional, diffusion, and quantitative MRI. These techniques are being adopted worldwide to map brain functions and structures with unprecedented acquisition speed, image resolution, data quality, and information content.

For example, the EPTI technique she developed introduces a novel MRI readout that addresses EPI’s major limitations while providing rich multi-contrast information. EPTI-based fMRI techniques have improved the sensitivity and specificity of functional mapping, and are supported by multiple NIH and BRAIN Initiative grants as the next-gen fMRI acquisition to advance brain function studies. Dr. Wang’s research also focuses on diffusion MRI. Her dMRI techniques have resulted in substantial improvements in SNR efficiency, motion robustness, and spatial resolution. The submillimeter in-vivo diffusion Connectome dataset she published has been used by researchers globally to study previously inaccessible but vital brain circuitries important in Alzheimer’s disease, Parkinson’s disease, etc. Her recent dMRI developments further push the boundaries of achievable resolution in in-vivo dMRI to a mesoscopic scale (~0.1 mm3) at both 3T and 7T. Another area of her research is quantitative MRI, where she has developed ultra-fast multi-parametric imaging with high isotropic resolution (T1, T2, T2*, PD, and B1 maps at 1-mm iso within 3 mins) that has been employed in clinical studies with patients.

Dr. Raij is a researcher currently serving as the Director of Transcranial Magnetic Stimulation (TMS) Clinical Research at the Martinos Center. He aims to understand the human brain mechanisms and improve the treatment of psychiatric and neurological disease, such as depression, schizophrenia, cocaine addiction, chronic pain, traumatic brain injury and stroke.

In psychiatry, his recent work focuses on optimizing the efficacy of brain stimulation treatments in depression and cocaine addiction. He is also examining basic mechanisms and potential TMS treatments of PTSD and anxiety, including manipulation of memories by using non-invasive brain stimulation. In addition, he is mapping neuronal activation trace lifetimes in schizophrenia and depression, and studying how their abnormalities may be linked to symptoms. In cognitive neuroscience and neurology, he studies how large-scale integration over multiple human brain systems occurs (multisensory integration), and how cortico-cortical paired associative stimulation with multi-channel TMS could be used to re-wire connectivity between brain areas in health and in disease. To reach these goals, he uses a wide array of non-invasive human brain imaging and stimulation techniques (TMS, MEG/EEG, MRI/DTI/fMRI) and their combinations.

Dr. Cooley’s research interests lie in the development of high-impact imaging systems based on new approaches to hardware, image encoding, and signal processing. Her primary scientific contribution has been the development of a portable MRI brain scanner that uses a new image encoding technique. Low-cost, portable MRI systems have the potential to make MR imaging possible at sites where it is currently unavailable (due to cost and siting requirements). Conventional MRI scanners rely on a large homogeneous superconducting magnet and linear fast-slewing gradient magnetic fields for image encoding. It is infeasible to scale down a scanner with these design constraints to a truly portable human brain scanner. Instead, we developed a new approach which uses a lightweight, low-cost permanent magnet array to produce an inhomogeneous magnet field. Instead of considering this field variation as a nuisance, Dr. Cooley and colleagues use it to their advantage for image encoding in lieu of a linear read-out gradient system. Careful measurements and modeling of the system is conducted to enable a generalized encoding-matrix based generalized image reconstruction.

Dr. Cooley is also involved in the Magnetic Particle Imaging (MPI) hardware development effort at MGH. MPI shows great potential as a clinical, tracer-based imaging method with much higher sensitivity than MRI. Although the potential has been demonstrated in rodents for applications like angiography and cell-tracking, functional brain imaging has not been demonstrated. She and colleagues have developed a single-sided MPI detector to produce a low-distortion AC drive field and record the non-linear response of injected superparamagnetic iron-oxide nanoparticles (SPIONs). The measured signal tracks the local blood volume of a rat under the detector. They have recently obtained experimental results clearly demonstrating a dynamic MPI signal corresponding to CBV changes with hypercapnia. This work is has been expanded to the development of a functional MPI (fMPI) scanner for rats. Their work is now ongoing to develop the first human-scale MPI scanner for fMPI.

Dr. Chen’s research lies at the interface of neuroimaging technology, signal processing and neuroscience. She is interested in integrating state-of-the-art fMRI and multi-modal imaging techniques to achieve novel, comprehensive insights into our brain’s function and physiology. One line of her current research is to harness the cortical-depth-dependent information uncovered by high-resolution fMRI to improve the neuronal specificity and sensitivity of BOLD fMRI measures; and to exploit the depth-dependent patterns of resting-state brain functional architecture. A second line of her research focuses on integrating state-of-the-art fast PET technology and fMRI to probe the neuronal, vascular, energetic and neuromodulatory mechanisms underlying brain functional dynamics.
