Stephen Tucker

Stephen Tucker is Professor of Biophysics at the University of Oxford, affiliated with the Sub-Department of Condensed Matter Physics and based at the Kavli Institute for Nanoscience Discovery. His laboratory focuses on understanding the structural and functional mechanisms of ion channels, with particular expertise in potassium channels (K2P family), hydrophobic gating phenomena, and membrane protein biophysics.

His research integrates computational approaches (molecular dynamics, free-energy calculations) with structural biology (cryo-EM, crystallography) to study:

• Mechanosensitive channel activation and lipid regulation
• Hydrophobic gating mechanisms in nanopores
• Structural basis of ion selectivity and permeation
• Disease-associated mutations in transport proteins
• Development of nanobody-based channel modulators

Professor Tucker's recent publications (2015-2025) demonstrate consistent focus on potassium channel structure-function relationships, with advanced applications of cryo-EM and molecular dynamics simulations. Key trends include mechanistic studies of TREK/TASK channel gating, computational modeling of hydrophobic barriers, and structural insights into lipid-regulated ion conduction. His work frequently appears in high-impact journals including Nature, Science, and Nature Communications.

He leads the 'Ion channels' research group at the Kavli Institute, utilizing state-of-the-art facilities for structural biology and biophysical characterization. Laboratory work emphasizes interdisciplinary approaches combining computational biophysics with experimental validation.
