We specialize in unconventional, multi-disciplinary approaches to studying the heart at the intersection of applied mathematics, physics and computer science. We focus on theory development that leads to new technology and value delivery to the society. Currently we have three research programs:
1. Precision Medicine
To develop a quantitative approach to personalized risk assessment for stroke and dementia based on patent-specific heart anatomy, function and blood flow.
Disciplines: Cardiac Hemodynamics; Medical Imaging Physics; Continuum Mechanics; Computational Fluid Dynamics
2. Information Theory
To quantify and perturb cardiac fibrillation that emerges as a macro-scale behavior of the heart from micro-scale behaviors of inter-dependent components.
Disciplines: Cardiac Electrophysiology; Spiral Wave; Information Theory; Complex Networks
3. Artificial Intelligence
To develop artificial intelligence algorithms to predict the future risk of heart attack, stroke and sudden... death, and to assist surgical interventions to prevent these outcomes.
Disciplines: Medical Imaging Physics; Artificial Intelligence; Robotically Assisted Interventions
The APL Health Technologies program's functional restoration focus area includes two portfolios with particular relevance in neurology. The first focuses on motor restoration, using teams with expertise in robotics, microsensors, haptics, artificial intelligence and brain-machine interfaces. One set of projects, currently sponsored by Defense Advanced Research Projects Agency (DARPA) and the Henry Jackson Foundation, centers on a bionic arm technology that integrates with bone and muscle in amputee patients, restoring a variety of normal functions to the patient like cooking, folding clothing, hand shaking, and hand gestures. This portfolio explores direct brain control of the bionic limb, through work led by Dr. Nathan Crone of Johns Hopkins Neurology and Dr. Pablo Celnik of Johns Hopkins Physical Medicine and Rehabilitation. Another set of related work aims to restore motor function by better understanding and using brain signals through brain-machine interfaces. This work is current...ly funded by the National Science Foundation and industry partners. Also in the functional restoration focus area is the vision restoration portfolio. In a partnership with Second Sight and the Mann Fund, the work aims to enhance function of a bionic eye, which couples a retinal implant with a computer vision system to restore vision in blind individuals with retinitis pigmentosa. Current work in the human-machine teaming focus area includes a portfolio that is building artificial intelligence systems that improve radiologic and ophthalmic diagnostics. Another portfolio, currently focused in the surgical setting, enhances the physician's ability to visualize and manipulate the physical world, such as with orthopaedic surgery. view less
Directed by Debraj “Raj” Mukherjee, MD, MPH, the laboratory focuses on improving access to care, reducing disparities, maximizing surgical outcomes, and optimizing quality of life for patients with brain and skull base tumors.
The laboratory achieves these aims by creating and analyzing institutional and national databases, developing and validating novel patient-centered quality of life instruments, leveraging machine learning and artificial intelligence platforms to risk-stratify vulnerable patient populations, and designing novel surgical trials to push the boundaries of neurosurgical innovation.
Our research also investigates novel approaches to improve neurosurgical medical education including studying the utility of video-based surgical coaching and the design of new operative instrumentation.
