People
John A. Detre, MD
Principal Investigator
I am Professor of Neurology and Radiology at the University of Pennsylvania Perelman School of Medicine. I am founding Director of the Center for Functional Neuroimaging in the Department of Radiology, co-Director of the Center for Advanced Magnetic Resonance and Spectroscopy, and Vice Chair for Research in the Department of Neurology. I received my bachelors and medical degrees from Yale, completed fellowships in biophysics at both Carnegie Mellon University and the University of Pennsylvania, and completed neurology residency at Penn, where I’ve been on the faculty since 1993.
I have been continuously NIH-funded since 1993 and am author or co-author of over 300 original manuscripts. Much of my research concerns the development and validation of methods for noninvasively measuring regional cerebral blood flow, and the application of these methods in basic and clinical neuroscience. I am co-inventor of arterial spin labeled perfusion MRI, which has been translated to clinical use, but remains a powerful research tool for measuring regional brain function. I also carry out research using other MRI modalities, as well as with optical methods for bedside monitoring of brain function. My main current interests include cerebrovascular physiology and neurodegeneration, but I also work in stroke, epilepsy, traumatic brain injury, sleep, and affective disorders.
Drawing upon my interdisciplinary training, collaborations, and leadership skills, I lead efforts to provide core support for neuroimaging research on the Penn Campus. I was Principal Investigator of an NIH funded P30 Center Core in Neuroscience Neuroimaging for until early 2019 and am now co-PI of an NIH P30 Alzheimer’s Disease Neuroimaging Core. I also lead a core project on imaging brain structure and function in the NIH P41 Center for Magnetic Resonance and Optical Imaging where I also participate in technology development of metabolic imaging methods.
I am extremely active in mentoring of trainees from both biophysical and biomedical backgrounds pursuing careers in biomedical neuroimaging. I was the recipient of an NIH Mid-career Award in Patient Oriented Research and Mentoring and currently serve as Principal Investigator of an NIH training grant targeting the career development of academically oriented neurology residents and fellows and as co-PI of three additional NIH T32 training programs.
Sudipto Dolui
Research Associate
Sudipto Dolui received his Ph.D. in Electrical Engineering from the University of Waterloo in Canada. Prior to that, he obtained his Masters (M.Tech.) from IIT Delhi, and his Bachelors of Engineering (B.E.) from Jadavpur University, both in India. He was the recipient of Dr. Shankar Dayal Sharma (former President of India) Gold Medal from IIT Delhi in 2006-07. Throughout his research career, Dr. Dolui has been involved in varied fields of signal and image processing with primary interests in image denoising, deblurring, segmentation, compressed sensing and their applications. His current focus is on developing and validating signal processing strategies for arterial spin labeling (ASL) and studying changes in cerebral blood flow (CBF) patterns in different neurodegenerative diseases.
Jeffrey Ware, MD
Postdoctoral Researcher
Dr. Ware is currently a neuroradiology fellow at the Hospital of the University of Pennsylvania, where he completed radiology residency in 2016. Prior to radiology residency, he completed medical school at the Columbia University College of Physicians and Surgeons and received a bachelor’s degree from Syracuse University. Dr. Ware’s research focuses on the application of translational neuroscience imaging techniques such as structural morphometry, diffusion imaging, functional magnetic resonance imaging and arterial spin labeling perfusion to the study and clinical evaluation of traumatic brain injury.
Eileen Hwuang
Graduate Student
Eileen Hwuang is a PhD student in bioengineering at the University of Pennsylvania School of Engineering. She graduated from Rutgers University-New Brunswick in 2014 with a bachelor’s degree in biomedical engineering. Eileen is an Interfaces Program scholar and an NSF GRFP fellow. Her research interests are in developing MRI techniques to image placental perfusion and flow. Eileen is jointly advised by Dr. John Detre and Dr. Walter Witschey.
Shokufeh Sadaghiani, MD
Postdoctoral Researcher
Shokufeh is a postdoctoral researcher working mainly on development of MRI biomarkers for neurological disorders. Her current work focuses on implementation of arterial spin labeling (ASL)-derived biomarkers in studying cerebrovascular contributions of cognitive impairment and dementia.
Prior to joining the lab, she earned her medical degree from Tehran University of Medical Sciences and her interest is translational research on diagnosis and progression of neurological diseases in order to find therapeutic targets for them.
Mohammad Taghvaei, MD, MPH
Postdoctoral Researcher
Mohammad received his M.D. from Tehran University of Medical Sciences and completed neurosurgery residency in 2017. His research interest is imaging biomarkers of neurological diseases. Mohammad currently works on the effect of age-associated white matter hyperintensity lesions on tractography-based brain structural connectivity through virtual lesion connectome approach. He also evaluates the associations between cognitive deficits and connectivity in white matter tracts that subserve different cognitive functions.
Will Tackett
Research Specialist
Will works as part of a precision neuroimaging research initiative which seeks to apply research-grade image acquisition and data processing capabilities to the clinic. His current projects involve utilizing fMRI to lateralize language and memory areas in presurgical epilepsy patients and quantifying cerebrovascular activity with ASL. Before joining the lab, he earned a BA in neuroscience from Dartmouth College and received honors for his senior thesis investigating the role of nigrostriatal dopamine in sign-tracking. He is interested in using neuroimaging to develop better understanding and treatment of neurological and psychiatric disorders.
