Liman, Emily
Harold W. Dornsife Chair in Neuroscience and Professor of Biological Sciences
The Liman lab studies how ion channels enable sensory cells to convert chemical and mechanical cues into electrical signals. We discovered the Otopetrin (OTOP) family of proton-selective ion channels and showed that OTOP1 is the long-sought sour-taste receptor as well as a detector of ammonium. Using patch-clamp electrophysiology, structure-guided mutagenesis, cryo-EM, and in vivo genetics we aim to reveal how protons permeate OTOP pores, how gating is tuned by pH and lipids, and how channel activity shapes taste, balance, and metabolic physiology. Ongoing projects extend these questions to other OTOP isoforms combining medium-throughput screening with computational modeling to identify first-in-class modulators and mouse genetics to identify and manipulate cells that express OTOP channels. Students gain rigorous cross-disciplinary training in membrane biophysics and sensory neuroscience while working in a collaborative, inclusive environment.
Lyden, Patrick
Professor of Physiology and Neuroscience and Neurology
The Lyden lab has been funded by NIH, VA and AHA for over 30 years. The lab is focused on translational pre-clinical stroke modeling, pharmacology, and vascular biology. The lab has considerable experience with a variety of animal models; behavioral testing; histology; and cell biology. The lab was selected by NINDS to develop and manage the Stroke Preclinical Assessment Network (SPAN) as the Coordinating Center. Current projects include studies to determine the mechanisms of differential vulnerability in the neurovascular unit; effects of microglial activation on neuronal survival; and blood brain barrier disruption during stroke and mild traumatic brain injury.
McKemy, David
Professor of Biological Sciences
The McKemy laboratory studies the neurobiological basis of pain, focusing on general somatic sensations of pain, painful neuropathies associated with chronic injury and disease, and the mechanisms that lead to migraine headaches. The lab is also interested in how the microbiome alters general physiological functions that can lead to pain and other disorders.
Moore, Jeffrey
Assistant Professor of Biological Sciences
Many mammals sense and affect their environment predominantly through innate motor programs for exploration, social interaction, and ingestion; yet, little is known about the neuronal circuits that control these motor programs. Our lab uses molecular, systems, and computational neurobiological techniques to identify specific brainstem motor control modules and to determine how higher-order brain structures engage these modules for innate behaviors.
Petzinger, Giselle
Associate Professor of Neurology (Clinical Scholar)
Dr. Giselle M. Petzinger is a Movement Disorders Specialist and neuroscientist in the department of neurology at USC Keck School of Medicine. Her training includes MD at USC, Neurology Residency at Yale, Fellowship at Columbia University and experimental therapeutics at the Parkinson’s Institute in the bay area. Her research involves animal models and clinical studies to investigate lifestyle on cognitive/motor function and synaptic plasticity in frontal-striatal and cerebellum circuits. Other studies include investigating the relationship between motor performance and cognitive function and related circuitry in PD and the role of compensation using behavioral, neuroimaging and neurophysiologic metrics. Her work also focuses on understanding neuro-energetic mechanisms of synaptic plasticity in PD focused on mitochondrial function and L-Lactate.
