Rate My Professor Kirk L. Hamilton

Kirk L. Hamilton is an Associate Professor in the Department of Physiology at the University of Otago, where he joined in 1994. He holds an MA from the University of Texas and a PhD from Utah State University. Hamilton's research specializes in the molecular regulation, physiology, and function of ion channels in epithelial tissues. His work particularly examines the trafficking and regulation of potassium channels, including the human intermediate-conductance Ca²⁺-activated K⁺ channel (KCa3.1) and the one transmembrane domain K⁺ channel β-subunits KCNE1 and KCNE3. He utilizes biotin-ligase acceptor peptide (BLAP) technology to tag these channels and study their cellular and membrane trafficking. Hamilton also investigates the broader role of KCa3.1 in cell biology and collaborates with the Auckland Bioengineering Institute on mathematical modeling to develop comprehensive biophysical models of nephron function and multi-nephron complexes.

Hamilton has made significant contributions through editorial and authorship roles in seminal works on epithelial transport. He co-edited Studies of Epithelial Transporters and Ion Channels: Ion Channels and Transporters of Epithelia in Health and Disease, Volume 3 (Springer, 2020), and contributed chapters such as KCa3.1 in Epithelia and Techniques of Epithelial Transport Physiology in Basic Epithelial Ion Transport Principles and Function (2020). Key recent publications include The exocyst complex is required for the trafficking and delivery of KCa3.1 to the basolateral membrane of polarized epithelia (American Journal of Physiology: Cell Physiology, 2023), Role of SNARE Proteins in the Insertion of KCa3.1 in the Plasma Membrane of a Polarized Epithelium (Frontiers in Physiology, 2022), and The Role of Retromer in the Trafficking of the Ca²⁺-activated K⁺ channels KCa2.3 and KCa3.1 (FASEB Journal, 2021). Earlier influential papers encompass Glucose transport into everted sacs of the small intestine of mice (Advances in Physiology Education, 2013), Single-channel recordings from amiloride-sensitive epithelial sodium channel (American Journal of Physiology-Cell Physiology, 1985), and Basolateral membrane K⁺ channels in renal epithelial cells (American Journal of Physiology-Renal Physiology, 2012). His research has advanced knowledge of ion channel dynamics in epithelial function and disease.
