  • Athir Morad Lab

    Research in the Athir Morad Lab primarily focuses on perioperative pain management for neurosurgery patients. Our team has conducted two randomized controlled trials to assess the efficacy of patient-controlled analgesia (PCA) following craniotomy. Our current research includes studies on the safety of opioid administration following craniotomy through the use of end-tidal CO2 detection, as well as research into the use of transcortical magnetic stimulation (TMS) for managing pain after spine surgery.

    Research Areas: neurosurgery, opioids, spine, anesthesiology, pain

  • Carey Research Group

    John Carey’s Research Group conducts research regarding diseases of the inner ear that affect both balance and hearing mechanisms. Key interests include superior semicircular canal dehiscence syndrome (SCDS), the normal vestibular reflexes and how they change with age, novel intratympanic treatments (i.e., middle ear injections) for conditions like Menière’s disease and sudden hearing loss, and the mechanisms of vestibular migraine. With Lloyd Minor, Dr. Carey helped develop the operation to repair the superior canal in patients with SCDS using image-guided surgery. Dr. Carey has been funded by the National Institutes of Health – National Institute on Deafness and Other Communication Disorders to study inner ear balance function in Menière’s disease and steroid treatment of sudden hearing loss.

    Research Areas: meniere's disease, vertigo, audiology, neurotology/otology, superior canal dehiscence, cochlear implant, hearing loss

  • Clemens Lab

    Research in the Clemens Lab focuses on identification of the cellular and molecular mechanisms that mediate bone formation and repair. Currently, we are studying the role of sensory nerves in bone and the coupling of bone cell metabolic activity to the sensory nerves' development and function.

    The skeleton is one of the most important structures in our bodies. Bones allow us to stand, walk and move from one place to another, and they serve as protectors of our vital organs. With aging, our skeleton both loses its bone mineral and the structure (micro-architecture). The fine trabecular bone is organized into plates and rods, and these structures develop cracks and discontinuity. As we age, bone is lost and its structure compromised. This degradation of our bone structure — osteoporosis — is a global health problem. Thomas Clemens, M.D. is the director of the Clemens lab. He is the Lewis Cass Spencer professor of orthopaedic surgery and the vice chair for research in the Department of... Orthopaedic Surgery at Johns Hopkins. view less

  • David Thompson Lab

    Researchers in the David Thompson Lab examine the outcomes of patients treated in intensive care units (ICUs), patient safety efforts, quality improvement efforts, and multidisciplinary teamwork and safety curriculum development. We're taking part in a study aimed at reducing hospital-acquired infections among cardiovascular surgery patients. Our investigators also participated in a clinical research collaboration that saw an 81 percent reduction in bloodstream infections related to central lines.

    Research Areas: medical education, patient safety, quality improvement, infections, patient outcomes, ICU

  • Grant (Xuguang) Tao Lab

    Research in the Grant (Xuguang) Tao Lab explores environmental and occupational epidemiology topics, including workers' compensation and injuries, and nosocomial infections. We conduct research through clinical trials and systematic literature reviews, and also use cancer registry data and GIS applications in environmental epidemiological research. Our recent studies have explored topics such as the effectiveness of lumbar epidural steroid injections following lumbar surgery, the effect of physician-dispensed medication on workers' compensation claim outcomes and how the use of opioid and psychotropic medications for workers' compensation claims impacts lost work time.

    Research Areas: epidemiology, drug safety, cancer, nosocomial infections, GIS applications

  • Health Technologies

    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

  • Interventional Cardiology Research Group

    Our group is interested in a broad array of clinical and translational investigations spanning the evaluation of basic pathophysiology in patients undergoing cardiac procedures, development and evaluation of new therapeutic strategies, and improving patient selection and outcomes following interventional procedures. We are comprised of a core group of faculty and dedicated research nurses as well as fellows, residents, and students. Projects range from investigator-initiated single-center observational studies to industry-sponsored multicenter phase 3 randomized controlled trials. We have established a database of all patients who have undergone TAVR at Johns Hopkins, which is providing the basis for several retrospective analyses and will serve as the foundation for future studies of TAVR. We are also engaged in collaborative projects with other groups from the Department of Medicine and other Departments including Cardiac Surgery, Anesthesiology, Radiology, Psychiatry, and Biomedical... Engineering. Members of our group are actively involved with the Johns Hopkins Center for Bioengineering Innovation and Design (CBID) in the development of novel minimally-invasive cardiovascular devices. view more

  • Jeffrey Dodd-o Lab

    Research in the Jeffrey Dodd-o Lab aims to better understand the contributing factors of lung ischemia/reperfusion injuries and the role these injuries play in the lung dysfunction of patients soon after cardiopulmonary bypass surgery. We have created an ischemia/reperfusion model in a spontaneously breathing mouse that they use with an in situ mouse lung preparation to identify cardiopulmonary interactions that impact reperfusion-related lung injury. We are working to characterize the influence of atrial natriuretic peptide (ANP) on lung microvascular permeability.

    Research Areas: lung ischemia, ischemia-reperfusion injury, cardiopulmonary diseases, atrial natriuretic peptides
