M Bruce MacIver

Professor (Research) of Anesthesiology, Perioperative and Pain Medicine, Emeritus

Current Research and Scholarly InterestsWe study drug effects on the nervous system. Cellular, synaptic and molecular drug actions are investigated using electrophysiological and pharmacological tools in cortical/hippocampal brain slice preparations. We are also interested in mechanisms of neuronal integration and synchronization, especially related to patterns of EEG activity seen in vivo and in brain slices.

Edward R. Mariano, MD, MAS, FASA, FASRA

Professor of Anesthesiology, Perioperative and Pain Medicine (MSD)

Current Research and Scholarly InterestsMy clinical research interests include the development of techniques and patient care pathways to improve postoperative pain control and other surgical outcomes. I am particularly interested in using regional anesthesiology, the science and practice of modulating nerve transmission in the central neuraxis or within peripheral nerves, to produce target-specific and opioid-sparing pain relief and enhance recovery after surgery or injury.

Amy Li Matecki

Adjunct Clinical Instructor, Anesthesiology, Perioperative and Pain Medicine

BioDr. Amy (Ying Li) Matecki has been licensed to practice medicine in California since 2002 and completed her Internal Medicine Residency as Chief Resident at Highland Hospital, Alameda Health System, a UCSF affiliate, in 2004. She received her degree in Acupuncture and Chinese medicine from ACCHS in 2009. She was a Faculty Attending Physician at Department of Medicine Residency at Highland Hospital from 2004 to 2019 and Chief of the Integrative Medicine Division from 2014 to 2019. She and her colleagues from allopathic medicine and Chinese Medicine created hospital privilege policy for licensed acupuncturists in 2011 and designed policies, procedures and training methods for acupuncturists to join the medical staff to provide inpatient acupuncture services at Highland Hospital. She helped to create the first Traditional Chinese Medicine (TCM) Residency from 2016 to 2019 at Alameda Health System Highland Hospital. Graduates from this residency program are able to work in allopathic academic teaching hospitals’ inpatient care and outpatient medical centers.

In addition to serving in the public hospital, Dr. Matecki joined Alta Bates Summit Medical Center (ABSMC) Comprehensive Cancer Center in 2004 where she started a community hospital-based acupuncture program to bridge Eastern and Western Medicine. She has been the Medical Director of Integrative Medicine at ABSMC since 2008. Integrating Chinese Medicine into conventional oncology practice, Dr. Matecki and her team not only provide clinical care but also present and publish their findings on safety from using acupuncture and integrative medicine to reduce the pain, nausea and anxiety that frequently accompanies conventional cancer treatments. In many case level observations, Dr. Matecki and her team note that the integration of Chinese Medicine may enhance cancer patients' quality of life.

Dr. Matecki was the principal investigator (PI) for acupuncture research for chronic post-chemotherapy fatigue in collaboration with Memorial Sloan-Kettering Cancer Center in New York. She presented her study on the safety of acupuncture for patients with lymphedema at the American Society of Clinical Oncology Breast Cancer Symposium in October 2009. She was co-investigator in a public hospital that studied acupuncture feasibility for Intensive Care Unit (ICU) patients which was published in the Journal of Alternative and Complementary Medicine (JACM) in 2017. She is the current PI for a Chinese herbal medicine research project at ABSMC. Following her team’s previous success at Highland hospital, she pioneered the first Sutter Bay Hospital Integrative Medicine TCM Residency training program at Alta Bates Summit Medical Center in 2023. https://vitals.sutterhealth.org/east-meets-west-health-system-launches-its-first-traditional-chinese-medicine-clinical-training-program/
