    Dáibhid Ó Maoiléidigh, PhD

    Assistant Professor of Otolaryngology - Head & Neck Surgery (OHNS)

    Current Research and Scholarly InterestsThe Ó Maoiléidigh group employs mathematical and computational approaches to better understand normal hearing and hearing impairment. Because complete restoration of auditory function by artificial devices or regenerative treatments will only be possible when experiments and computational modeling align, we work closely with experimental laboratories. Our goal is to understand contemporary experimental observations, to make experimentally testable predictions, and to motivate new experiments. We are pursuing several projects.

    Hair-Bundle Mechanics

    Auditory and balance organs rely on hair cells to convert mechanical vibrations into electrical signals for transmission to the brain. In response to the quietest sounds we can hear, the hair cell's mechanical sensor, the hair bundle, moves by less than one-billionth of a meter. To determine how this astounding sensitivity is possible, we construct computational models of hair-bundle mechanics. By comparing models with experimental observations, we are learning how a hair bundle's geometry, material properties, and ability to move spontaneously determine its function.

    Cochlear Mechanics

    The cochlea contains the auditory organ that houses the sensory hair cells in mammals. Vibrations in the cochlea arising from sound are amplified more than a thousandfold by the ear's active process. New experimental techniques have additionally revealed that the cochlea vibrates in a complex manner in response to sound. We use computational models to interpret these observations and to make hypotheses about how the cochlea works.

    Lucy Erin O'Brien

    Associate Professor of Molecular and Cellular Physiology

    Current Research and Scholarly InterestsMany adult organs tune their functional capacity to variable levels of physiologic demand. Adaptive organ resizing breaks the allometry of the body plan that was established during development, suggesting that it occurs through different mechanisms. Emerging evidence points to stem cells as key players in these mechanisms. We use the Drosophila midgut, a stem-cell based organ analogous to the vertebrate small intestine, as a simple model to uncover the rules that govern adaptive remodeling.

  • Lauren O'Connell

    Lauren O'Connell

    Assistant Professor of Biology

    Current Research and Scholarly InterestsThe O'Connell lab studies how genetic and environmental factors contribute to biological diversity and adaptation. We are particularly interested in understanding (1) how behavior evolves through changes in brain function and (2) how animal physiology evolves through repurposing existing cellular components.

  • Detlef Obal

    Detlef Obal

    Assistant Professor of Anesthesiology, Perioperative and Pain Medicine (Adult MSD)

    Current Research and Scholarly InterestsI am primarily working at the Cardiovascular Institute (Director Joseph Wu, MD, PhD), studying the effect of different anesthetics on human induced pluripotent stem cells (hiPSC). Considering the current opioid epidemic, I am currently focusing on the effect of chronic opioid exposure on endothelial and cardiac function.

    Current Research and Scholarly InterestsMy research is in statistics and their applications to medicine and biology. Many efforts have concerned tree-structured algorithms for classification, regression, survival analysis, and clustering.

  • Lisa A. Orloff, MD, FACS, FACE

    Lisa A. Orloff, MD, FACS, FACE

    Professor of Otolaryngology - Head & Neck Surgery (OHNS)

    BioLisa A. Orloff, MD, FACS, FACE is Director of the Endocrine Head and Neck Surgery Program and Professor in the Department of Otolaryngology, Division of Head and Neck Surgery, at Stanford University School of Medicine. She is Director of the Stanford Thyroid Tumor Program within the Stanford Cancer Center. Her clinical practice focuses on the surgical management of thyroid and parathyroid tumors and disorders.

    Dr. Orloff is an internationally recognized leader in the field of endocrine head and neck surgery. She is also an expert in the application of ultrasonography to the diagnosis and management of diseases of the head and neck, with an emphasis on thyroid cancer. Dr. Orloff performs minimally invasive ultrasound-guided procedures such as radiofrequency ablation for the nonsurgical management of appropriate thyroid pathology. Her background in microvascular and laryngeal surgical techniques lends a unique level of refinement to her endocrine surgical practice. A major component of her clinical work is the management of persistent or recurrent thyroid cancer. Dr. Orloff’s multidisciplinary approach to the management of endocrine head and neck disease involves collaboration with her colleagues in other specialties at Stanford and throughout the country. Dr. Orloff also studies the regeneration of tissue that has been lost as a result of cancer therapies. 

    Dr. Orloff received her bachelor’s degree at Stanford, and her medical degree from the University of California, Los Angeles. She completed her residency in Otolaryngology/Head & Neck Surgery at the University of Washington and a visiting fellowship in Microvascular & Reconstructive Surgery at Mount Sinai Medical Center in New York. Prior to joining the faculty at Stanford, she was the Robert K. Werbe Distinguished Professor in Head and Neck Cancer, and Chief of the Division of Head and Neck Surgery at the University of California, San Francisco (UCSF.)

    Dr. Orloff served three consecutive terms as the Chair of the American Academy of Otolaryngology—Head and Neck Surgery (AAO-HNS) Endocrine Surgery committee, and served for many years as a voting member of the FDA’s Panel to evaluate medical devices for Otolaryngology. She holds leadership roles within the American Head and Neck Society, the American Thyroid Association, the American Institute of Ultrasound in Medicine, and the American College of Surgeons. She is co-chair of the ACS Thyroid, Parathyroid, and Neck Ultrasound training program and a member of the ACS National Ultrasound Faculty executive board. She is also a member of such influential teams as the National Cancer Institute (NCI) steering committee on Thyroid Cancer Clinical Trials and the Endocrine Surgery Committee of the American Association of Clinical Endocrinology (AACE). She authored the leading textbook, Head and Neck Ultrasonography (Plural Publishing), as a reference for clinicians; the second edition was published in 2017. Dr. Orloff is a former Fulbright scholar.

    Kelly E. Ormond, MS, CGC

    Clinical Professor, Genetics

    Current Research and Scholarly InterestsI am currently serving as the Research Director for the MS in Human Genetics and Genetic Counseling program. My research focuses on the intersection between genetics and ethics, particularly around the translation of new genetic technologies (such as genome sequencing, non-invasive prenatal diagnosis and gene editing) into clinical practice. I am especially interested in patient decision making, consent and disclosure of genetic test results, and the interface between genetics and disability.
