About Stephanie Schorge
Stephanie Schorge, the current Pewterers Fellow, is the day-to-day supervisor of the Channelopathies group. Her current research revolves around a long-standing interest in the importance of RNA processing, particularly alternative splicing, in regulating ion channel biophysics. The work has evolved from a PhD project, supervised by Diane Lipscombe at Brown University, focused on the role of RNA processing (splicing and regulated degradation) in controlling calcium channel function. She spent five years investigating the subunit composition and single channel gating behavior of NMDA receptors with David Colquhoun, in the Pharmacology Department at UCL. After moving to IoN she worked with Dimitri Kullmann for a year on characterizing mutations in potassium and sodium channels linked to human neurological disorders. This position led to her current fellowship investigating how alternative splicing regulates sodium channel function in humans.
