Biography

Emily Liman is a cellular physiologist working at the interface of ion channel biophysics and sensory biology. Liman earned a BA in Biology from Princeton University and a PhD in Neuroscience from Harvard Medical School. She was a postdoctoral fellow at Harvard Medical School with Linda Buck and David Corey before joining the faculty at the University of Southern California where she is currently the Harold Dornsife Professor of Neuroscience. Liman is known for her work on sensory TRP channels and more recently for the discovery of the OTOP proton channels, one of which functions as a sour receptor. Among her honors, Liman is the 2023 recipient of the Cole award from the Biophysical Society.  Liman has been active in a number of scientific organizations, including service as the 2024 program chair for the annual meeting for the Association for Chemoreceptive Sciences.
