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. -

In June 2021, CPA was selected by the California GOTV medical academic consortium including the Stanford University School of Medicine as led by UCLA - to conduct the "Get Out the Vaccine to Stop Covid-19" initiative for low-income populations in Monterey County, California.
Since 2016 Dr. O'Brien has been on the Institutional Review Board of Clinica de Salud del Valle de Salinas. He is currently a member of the Stanford Cancer Institute Community Advisory Board. Dr. O’Brien is a past editor of the Berkeley Wellness Letter, Medicine on the Net and Cancer Informatics. -
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
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.

Ruth O'Hara
Director, Spectrum, Senior Associate Dean, Research and Lowell W. and Josephine Q. Berry Professor
Current Research and Scholarly InterestsDr. O'Hara's research aims to investigate how cognitive information processing deficits subserve affective symptoms in psychiatric disorders, and interact with key brain networks integral to these disorders. To do so, she has implemented a translational, interdisciplinary program that encompasses cellular models, brain and behavioral assays of affective and cognitive information processing systems in psychiatric disorders across the lifespan.

Sean J. O'Sullivan
Postdoctoral Scholar, Psychiatry
BioDr. Sean J. O’Sullivan is an MD/PhD postdoctoral scholar from Philadelphia. His PhD in neuroscience from Thomas Jefferson University focused on the molecular mechanisms of alcohol and opioid withdrawal.
Specifically, he took a systems neuroscience approach to understand the role of the gut microbiome in influencing the negative physical and emotional states that characterize alcohol and opioid withdrawal syndromes.
This work led to the generation of a novel hypothesis—interoceptive neuroinflammatory signaling involving gut dysbiosis and peripheral network decompensation secondary to abstinence in the context of allostasis drives neuroinflammation in the nucleus tractus solitarius (NTS) and amygdala during alcohol and opioid withdrawal which increases the severity of the withdrawal symptoms. He further conjectures that this interoceptive signaling constitutes an antireward pathway that motivates substance dependence via negative reinforcement.
He also investigated neuronal subphenotypes in the suprachiasmatic nucleus which is the principle circadian brain region. He further investigated how circadian rhythms affect gene expression in the NTS and amygdala.
In the Stanford Brain Stimulation Lab, Dr. O’Sullivan is part of the inpatient treatment team that is applying an accelerated transcranial magnetic stimulation (TMS) protocol (Stanford Accelerated Intelligent Neuromodulation Therapy [SAINT]) to hospitalized psychiatric patients. TMS is not currently available to psychiatric inpatients, and this work aims to make this innovative treatment available to those most in need. He is also leading a study researching the effects of TMS on a peripheral biomarker of depression known as L-acetyl-carnitine. He is in the process of applying for psychiatry residency and plans to integrate brain stimulation into his future clinical practice. -
