Positions Available

Postdoc Position Available to Study KCNMA1-Linked Channelopathy (Sept 2022)

Our research focuses on the mechanisms by which ion channels regulate information coding in the brain and other excitable cells. In my lab, we combine the genetic manipulation of ion channels with electrophysiology, imaging, and in vivo physiology. Two central goals of the lab are to identify the fundamental biophysical properties of ion channels that cause neurological diseases, and to identify the ion channel basis for state-dependent changes in action potential activity in the circadian clock of the brain. Techniques in the lab include voltage- and current-clamp recordings, multi-electrode array recordings, imaging/FRET, molecular biology, transgenics, and in vivo telemetry.

For this postdoctoral position, we are seeking a highly motivated team-player to contribute to our studies of a new ion channelopathy defined by mutations in KCNMA1, the gene encoding the large conductance Ca2+-activated BK channel. The project involves investigating KCNMA1 channelopathy patient mutations and their impact on BK currents in heterologous cells and neuronal excitability in mouse models.

Requirements: Candidates should have a PhD in biophysics, neuroscience, physiology, or other relevant field. Experience with electrophysiological recordings is required. Excellent oral and written communication skills should be demonstrated through publications and presentations.

To apply: Please send your application by email to Dr. Andrea Meredith, including:

  • your CV
  • a letter describing research accomplishments, expertise, and career goals
  • the names and contact information for three references
