Research interests include the regulation of Ca²⁺ and Mg²⁺ transport in epithelia with a specific focus on the molecular regulation of epithelial Ca²⁺ and Mg²⁺ channels (TRPV5&6 and TRPM6&7), members of the transient receptor potential (TRP) channels. Recent studies indicate that these channels function as gatekeepers to maintain the extracellular Ca²⁺ and Mg²⁺ balance which is crucial for mammalian development and function. His current work focuses on the functional aspects of these channels using a comprehensive approach that includes studies on epithelial cell lines and animal knockout models, identification of regulatory partners and electrophysiological analysis of channel activity.
