Dr. McNab is an MRI Physicist focused on the development of magnetic resonance imaging (MRI) contrast mechanisms and acquisition strategies that yield new and/or improved images of the in vivo human brain. Over the past decade, she has developed numerous MRI acquisition methods, with her primary contributions being in the field of diffusion MRI. Dr. McNab has extensive experience with the most cutting-edge MRI technology, including the world's strongest human-MRI gradients (300 mT/m), highly-parallelized phased-array RF coils (64-channels) and ultra-high magnetic field (7T).

Research Scientist

Physical Science Research Scientist, Rad/Radiological Sciences Laboratory


Dr. Leuze is working on techniques for visualization of MRI data using virtual and augmented reality devices. He has developed an MRI viewer for the Samsung Gear VR and has presented projects on MRI data volumetric visualization and registration to the real world using the Microsoft Hololens and the Intel RealSense camera. Dr. Leuze is furthermore refining MRI techniques for measuring brain circuits by validation with tissue clearing and optical imaging methods.

Post-Doctoral Fellows

Postdoctoral Research Fellow, Radiological Sciences Laboratory


Dr. Sathyanarayana is working on the Mixed-reality Neuronavigation project. She is currently working on developing accurate head and coil tracking techniques using depth cameras. Her prior work during her PhD was on facial feature detection and tracking for patient monitoring applications.
Postdoctoral Research Fellow, Radiological Sciences Laboratory

Dr. Erpeng Dai mainly focuses on technique development for high-resolution and high-efficiency diffusion MRI (dMRI). Previously, he optimized the navigator acquisition for multi-shot interleaved EPI dMRI and further combined it with simultaneous multi-slice (SMS) for improved scan efficiency. Meanwhile, he also merged SMS and multi-slab techniques (termed “SMSlab”) to achieve high-resolution isotropic imaging. Currently, Erpeng Dai is mainly working on high-resolution dMRI on ultra-high field (7T) systems.
Postdoctoral Research Fellow, Neurosurgery

Daniel A. N. Barbosa, M.D., is a Postdoctoral Scholar sponsored by Dr. Casey H. Halpern (Assistant Professor of Neurosurgery) and co-sponsored by Dr. Jennifer McNab (Assistant Professor of Radiology). He received his medical degree from the Federal University of the State of Rio de Janeiro in 2018. During his clinical education, Dr. Barbosa followed several renowned neurosurgeons and neurologists, and had a large experience with neurological and psychiatric patients. He developed great interest for the investigations of neurosurgical techniques to improve brain function. Now, he is working on multimodal imaging techniques to improve stereotactic targeting in on-demand, responsive neuromodulation (RNS) of the nucleus accumbens for pathological impulsivity, a pervasive symptom in a wide range of neurological and neuropsychiatric disorders. After a couple of years working on research, Dr. Barbosa plans to start his residency in Neurological Surgery and ultimately pursue his career in Stereotactic and Functional Neurosurgery.

Graduate Students
