The Marie Hanna Lab conducts research on key topics within the field of anesthesiology. Our interests include both regional and obstetric anesthesia as well as patient-controlled analgesia, pain measurement, post-operative pain and acute pain management. Examples of our work include researching whether a surgery patient’s perception of pain control affects his or her satisfaction level and a comparison of air and liquid for use in the loss-of-resistance technique during labor epidurals.

The studies of the Functional Neurosurgery Lab currently test whether neural activity related to the experimental vigilance and conditioned expectation toward pain can be described by interrelated networks in the brain. These two psychological dimensions play an important role in chronic pain syndromes, but their neuroscience is poorly understood. Our studies of spike trains and LFPs utilize an anatomically focused platform with high temporal resolution, which complements fMRI studies surveying the whole brain at lower resolution. This platform to analyze the oscillatory power of structures in the brain, and functional connections (interactions and synchrony and causal interactions) between these structures based upon signals recorded directly from the waking human brain during surgery for epilepsy and movement disorders, e.g. tremor. Our studies have demonstrated that behaviors related to vigilance and expectation are related to electrical signals from the cortex and subcortical structures. These projects are based upon the combined expertise of Dr. Nathan Crone in recordings and clinical management of the patients studied; Dr. Anna Korzeniewska in the analyses of signals recorded from the brain; Drs. Claudia Campbell, Luana Colloca and Rick Gracely in the clinical psychology and cognitive neurology of the expectation of pain and chronic pain; Dr. Joel Greenspan in quantitative sensory testing; and Dr. Martin Lindquist in the statistical techniques. Dr. Lenz has conducted studies of this type for more than thirty years with continuous NIH funding.

Investigators in the Roger Johns Lab are examining the molecular mechanisms behind the onset and continuation of chronic pain, particularly neuropathic pain. This work has led to a better understanding of the vast network of molecules at neuronal synapses, particularly the postsynaptic density (PSD), which is key to the propagation of pain signals. We're working to develop new analgesics that interfere with the PSD protein interactions in an effort to better treat patients who suffer from chronic pain.

Researchers in the Robert Greenberg Lab examine anesthesiology and critical care-related topics that include critical airway management, non-invasive fetal monitoring, neural blockade monitoring, pediatric acute pain management, cuffed oropharyngeal airway (COPA), pain informatics, and pediatric pain education and innovation.

The Ronen Shechter Lab is currently investigating a novel treatment for nerve pain induced by chemotherapy. Our previous research has involved studying the role and mechanism of peripheral opioids as well as the use of dorsal column stimulation to treat pain resulting from a condition affecting the nervous system.

Research in the Steven Cohen Lab focuses on pain—including fibromyalgia and neuropathic pain—with many studies investigating the causes and treatment of injuries among U.S. soldiers related to these topics.

Work in the Sivanesan Neuromodulation Laboratory (SNL) focuses on developing electrical stimulation therapies for treating neuropathic pain conditions and discovering novel applications for patients suffering from painful conditions. We study mechanisms of all modalities of spinal cord stimulation in the laboratory and aim to rapidly translate these discoveries to patient care. This bench to bedside approach facilitates a unique integration of the latest science with the clinical care of patients.

Research in the Steven Levin Lab focuses on chemical neurolysis, epiduroscopy (and training for physicians), opioid administration, and the use of alternative therapies for pain management. In collaboration with the American Society of Law, Medicine and Ethics and with funding from a Donahue Foundation Grant, we study social and ethical considerations in pain management. We have also been involved in clinical trials of novel analgesics.

Led by Stephen Wegener, Ph.D, this research group focuses on projects that have the potential to improve function and quality of life and reduce disability following injury or illness. These projects include research on cognitive, behavioral, psychological and health care system factors that affect outcomes following injury.

The Sydney Dy Lab has conducted extensive research on quality of care, patient safety and decision-making, with a focus on patients with cancer and other serious and terminal diseases. Our team seeks to improve health systems and services to optimize the use of technology and medication, particularly in end-of-life health care policy. Our research approach includes primary and quantitative data collection, quality measurement improvement, systematic literature reviews and analysis of secondary database.
