The LONI Resource is administered by a competent and experienced team of investigators and staff, and counseled by an expert panel of scientists, the Scientific Advisory Board.


Arthur Toga, Principal Investigator
Dr. Toga is the director of USC's Stevens Neuroimaging and Informatics Institute and Laboratory of Neuro Imaging (LONI), as well as Provost Professor of ophthalmology, neurology, psychiatry and the behavioral sciences, radiology, and engineering at the Keck School of Medicine of USC. He has developed sophisticated tools for brain atlasing, multidimensional modeling, and visualization. His lab also coordinates multi-site acquisition, analysis, and dissemination of data with national and international collaborators.
Meredith Braskie, Co-Investigator
Dr. Braskie’s research evaluates how genetic and environmental risk factors for Alzheimer’s Disease (AD) relate to brain structure, function, and connectivity throughout adulthood, with an emphasis on metabolic risk. She primarily studies cognitively intact adults and those with early mild cognitive impairment, studying how AD risk-related biological mechanisms and signaling pathways are associated with brain changes, using relevant blood and cerebrospinal fluid measures, as well as multimodal imaging (structural and functional MRI, diffusion tensor imaging, and PET).
Neda Jahanshad, Co-Investigator
Dr. Jahanshad is an assistant professor of neurology at USC's Stevens Neuroimaging and Informatics Institute. She studies how genetic variation influences brain structure and connectivity, and develops protocols for large-scale meta analyses of imaging data for the Enhancing Neuro Imaging Genetics Through Meta-Analysis (ENIGMA) consortium.
Scott Neu, Software Developer
Dr. Neu is an assistant professor of research at USC's Stevens Neuroimaging and Informatics Institute. He has more than ten years of experience in numerical methods and simulation, as well as the design and development of image processing and medical informatics software. In his current role, Dr. Neu develops comprehensive software architecture for LONI.
Hosung Kim, Co-Investigator
Dr. Kim is an assistant professor of neurology at USC's Stevens Neuroimaging and Informatics Institute. In the domains of neurology and neuropsychiatry, he has analyzed brain structural change over time in both healthy and pathological conditions. Dr. Kim also researches medical image processing and analysis.
Yonggang Shi, Project Lead
Dr. Shi is an assistant professor of neurology and electrical engineering at USC's Stevens Neuroimaging and Informatics Institute. Through his research, he aims to develop novel mathematical frameworks and algorithms for mapping brain structure and function, with a focus on using intrinsic geometry in surface mapping algorithms.
Paul Thompson, Principal Investigator
Dr. Thompson is director of the Imaging Genetics Center (IGC), associate director of USC's Stevens Neuroimaging and Informatics Institute, and associate dean for research at the Keck School of Medicine of USC. He is also a professor of neurology, psychiatry and the behavioral sciences, engineering, pediatrics, and ophthalmology. Dr. Thompson's research focuses on the neuroscience, mathematics, and algorithm development of brain imaging and mapping. He co-founded and directs the Enhancing Neuro Imaging Genetics Through Meta-Analysis (ENIGMA) consortium, a worldwide medical network of institutes studying the brain's major diseases.


Karen Crawford, Data Manager
Ms. Crawford received her Master of Library and Information Science degree from UCLA. At LONI, she plans and develops database and software applications, which support medical imaging and general laboratory operations. She has expertise with database management systems and the development of informatics systems
Grace Liang-Franco, Project Coordinator
Ms. Liang-Franco received her Master of Business Administration degree from Pepperdine University, and has extensive experience with executive-level administration. Her contributions to the Resource will include planning and execution of meetings and workshops, as well as coordinating publications and other logistics.
Tyler Ard, Research Associate
Dr. Ard received his Ph.D. in neuroscience from Brown University in 2013. His current focus is to improve the understanding of neuroscientific data through novel visualizations, with an emphasis on analyzing large-scale, high-dimensional data.
Ryan Cabeen, Postdoctoral Fellow
Dr. Cabeen received his Ph.D. in computer science from Brown University in 2016. His doctoral research focused on the development and evaluation of computational tools for using diffusion MRI to study white matter in the brain, for which he received the Brown Institute for Brain Science Graduate Research Award.
Rita Esquivel, Project Assistant
Ms. Esquivel will apply her management expertise to the Resource by coordinating and managing data upload and download activities; she will also provide support and guidance to study site personnel and researchers as needed.
Samuel Hobel, Programmer
Mr. Hobel will apply his programming expertise to the development, integration, and support of collaborative neuroinformatics software tools. He will design, build, test, and debug components of neuroinformatics software.
James Stanis, Web Developer
Mr. Stanis received his Master of Biomedical Visualization degree from University of Illinois at Chicago. His experience as a scientific visualizer and 3D medical animator enable him to contribute novel visualization components to the Resource.
Lu Zhao, Postdoctoral Fellow
Dr. Zhao received his Ph.D. in signal processing from Finland's Tampere University of Technology in 2010. At LONI, he develops and applies big data discovery methods for linking the genetics of brain changes to major neurodevelopmental and neurodegenerative disorders. He has led the development of numerous advanced tools to extract and manage large volumes of genomic and neuroimaging data.
