Brandon Togioka, M.D.

Brandon Togioka

Dr. Togioka serves as the OHSU anesthesiology and perioperative medicine internship year liaison. In this role, he helps guide anesthesiology interns as they navigate their first year as a doctor on the OHSU campus. The majority of his teaching occurs in the clinical setting either in the operating room or on labor and delivery. However, he also participates in the formal resident lecture series, in journal club meetings, and with oral board practice. 

Dr. Togioka is conducting clinical research to determine if a new drug, Sugammadex, with evidence of more complete neuromuscular reversal than traditional drugs can decrease the incidence of lung complications after surgery. He is also conducting clinical research on labor and delivery to determine (1) the interaction between ethnicity, primary language, and epidural usage and (2) a method to avoid general anesthesia when regional anesthesia is failing during cesarean section.  

Michael Aziz, M.D.

Michael Aziz

Michael Aziz is a clinical researcher with a keen interest in airway management with a specific focus on video laryngoscopy. He has conducted comparative trials of video laryngoscopy techniques against each other and against direct laryngoscopy. He is also an active investigator of observational outcomes research focused on database investigation. To this end, he has developed and maintained a local preoperative database for clinical research and quality improvement that serves to collaborate with a national group, the multi-centered preoperative outcomes group (MPOG) and the associated quality improvement effort (Aspire). 

Studies from MPOG have resulted in multiple publications and have helped develop the future scientists in the department. Thus far, these studies have focused on airway management, epidural use in the thrombocytopenia parturient, the relationship of beta blocker therapy to stroke, opioid use and persistent pain after surgery, and newly forged investigations that have integrated the Society for Thoracic Surgery database.  

James "Jim" Carson, Ph.D.

James "Jim" Carson

Most of my research has focused on developing and testing the efficacy of complementary and alternative medicine (CAM) therapies—especially mind/body treatments—for persistent pain conditions. My investigative efforts have been strongly influenced by my clinical work as a health psychologist specializing in conditions such as chronic back pain, fibromyalgia, cancer-related pain, and post-concussion syndrome. Prior to becoming a psychologist I was a meditation teacher for many years. Projects I have directed include the first-ever clinical trial of a loving-kindness meditation intervention, which reported improvements in pain and psychological stress in chronic low back pain patients; and a series of trials of a Mindful Yoga intervention demonstrating improvements in pain, fatigue, and emotional distress among patients with either fibromyalgia, or cancer-related pain. I have also collaborated on projects focused on tai chi, and traditional Chinese medicine, for chronic pain. Currently, I am the principal investigator for a project that will conduct a national survey of allopathic physicians at outpatient pain treatment centers in the U.S. to determine the availability, attitudes, and utilization of CAM services within their routine practices. This study will address the knowledge gap that exists regarding the process of care and actual delivery of CAM in outpatient pain centers, as distinct from what is known from CAM trials conducted in rigorous research settings.

Ryan Ivie, M.D.

Ryan Ivie

Ryan Ivie is an anesthesiologist with specialty training in Regional Anesthesia and Acute Pain Medicine. He works clinically as an adult anesthesiologist with a focus on performing ultrasound-guided peripheral nerve blocks and teaching these techniques to residents and fellows. His research interests include evaluating novel applications and modifications of regional anesthesia techniques and evidence-based improvement in the education of ultrasound-guided regional anesthesia. He is studying techniques to improve the success rate of thoracic epidural placement, the effect of changes in spinal procedure location on operating room efficiency, and the impact of patient education on ambulatory peripheral nerve block outcomes.

Austin Peters, M.D.

Austin Peters

Austin Peters, M.D., is an anesthesiologist clinician-scientist focusing on translational neuroscience. His research explores the brain's cellular response to injury and how anesthetic drugs affect recovery. He has previously collaborated with fellow APOM researcher Dr. Laura Villasana and work closely with his mentor, Dr. Eric Schnell. In addition to research, he serves as an anesthesiologist at APOM, with a clinical focus on neuroanesthesia as well as liver transplantation.

In his current research, he is evaluating ketamine's potential role in traumatic brain injury (TBI) treatment and recovery. Using a mouse model, he has identified unique and potentially beneficial effects of ketamine treatment in this setting, and am developing a translational project to explore and apply these findings to human TBI patients.

Katie Schenning, M.D., M.P.H.

Katie Schenning

In her clinical practice, Dr. Schenning provides anesthesia for adult patients undergoing all types of surgical procedures, and she specializes in caring for patients with neurological disorders.  

Dr. Schenning's research is focused on perioperative cognition. In older adults, I am working on using preoperative cognitive and frailty screening tests to predict deleterious postoperative neurocognitive outcomes such as postoperative delirium and cognitive dysfunction. I am also interested in biological determinants of postoperative neurocognitive disorders, including genetics and biological sex.  

Peter Schulman, M.D.

Peter Schulman

Dr. Peter Schulman practices both anesthesiology and critical care medicine.  He is the medical director of the Cardiovascular Intensive Care Unit (CVICU), and chief of the Division of Cardiac and Surgical Subspecialty Critical Care.  He started and directs a perioperative pacemaker and implantable cardioverter-defibrillator service.  His research focuses on perioperative cardiovascular risk reduction; a principle interest is patients with a cardiac pacemaker or Implantable cardioverter-defibrillator.

Glenn Woodworth, M.D.

Glenn Woodworth

Dr. Woodworth began his medical training in San Diego culminating in finishing his residency at the Mayo Clinic in Rochester, Minnesota. He currently is the Regional Anesthesia and Acute Pain Medicine Fellowship Director, and Associate Professor at Oregon Health and Science University in Portland, OR. In addition to his clinical duties, Dr. Woodworth is an active education researcher and is particularly interested in the assessment of competency, the effectiveness of different educational methods in medical education, and the use of education technology. He is a past FAER grant recipient for his work on the assessment of ultrasound interpretation skills for regional anesthesia and is currently the PI for a FAER grant looking at the achievement of competency as determined by the milestones. Dr. Woodworth is the Editor in Chief of the Anesthesia Education Toolbox, a collaboratively developed peer-reviewed web-site for anesthesia education. The Toolbox learning management system facilitates resident, fellow, and post-graduate continuing education in anesthesia. In his spare time, Dr. Woodworth enjoys spending time with his family, playing tennis and cooking.
