    Nneoma S. Wamkpah, MD MSCI

    Assistant Professor of Otolaryngology-Head & Neck Surgery

    BioDr. Nneoma Stephanie Wamkpah is a board-certified, fellowship-trained facial plastic and reconstructive surgeon at Stanford Health Care Ear, Nose, and Throat. She is also an assistant professor in the Department of Otolaryngology – Head & Neck Surgery, Division of Facial Plastic & Reconstructive Surgery at Stanford University School of Medicine.

    Dr. Wamkpah cares for patients with facial paralysis, nasal problems, and facial injuries. She performs both functional and cosmetic surgery, including rhinoplasty, facial trauma repair, and procedures to restore movement after nerve damage. Her approach focuses on improving how patients look and function while tailoring care to their individual needs and goals.

    As a physician-researcher, Dr. Wamkpah explores how facial plastic and reconstructive surgery affects patients’ quality of life and functional outcomes. She studies patient-reported measures to improve surgical quality, shared decision-making between patients and surgeons, and ways to ensure equitable access to reconstructive care. She is also interested in innovations in facial reanimation, evidence-based approaches to facial trauma management, and the impact of medical education on surgical planning and execution.

    Dr. Wamkpah has authored several book chapters as well as articles in peer-reviewed journals such as JAMA Otolaryngology – Head & Neck Surgery, Facial Plastic Surgery & Aesthetic Medicine, and Otolaryngology – Head and Neck Surgery. She has presented her work at national conferences, including the annual meetings of the American Academy of Otolaryngology – Head and Neck Surgery (AAO-HNS), the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS), and the Rhinoplasty Society.

    Dr. Wamkpah is a member of AAO-HNS, AAFPRS, and the Sir Charles Bell Society. She also volunteers her skills internationally, providing surgery for children and adults in resource-limited countries.

    Ziyan Wu

    Postdoctoral Scholar, Otolaryngology - Head & Neck Surgery

    BioZiyan’s primary research interest is environmental engineering, especially hydrology, water resources, and sustainable development. Besides, she would like to do some research of big data analysis. In her undergraduate career, she did a hydrology research project of “Development and Update of Rainfall and Runoff Intensity-Duration-Frequency Curves for Arizona State Counties in Response to Climate Change” with Dr. Amin Mohebbi at Northern Arizona University. In this project, she used Matlab and Excel to analysis the 1-minuite precipitation data for 60 years. This project combined hydrology, big data analysis, and computer coding. Ziyan is looking forward to doing more combined projects like this for her graduate study.

    Besides this project, Ziyan did another project with Dr. Junsxing Ho. The title of the project is “Evaluation of Dust Suppressant Mixed with different types of Soils in Unpaved Road: Lab experiment”. Ziyan did sets of lab experiments in this project, and from this project, she is pretty familiar with lab procedures and lab conduction.
