Research Interests

My research interests are focused on using synthetic nanopore platforms to create biomimetic materials, ionic circuits, supercapacitors, drug delivery systems and biosensors. I am currently leading a project aimed at developing artificial excitable ion channels capable of producing signal propagation analogous to that seen in a neuron. I am also a key member of teams working to study ion behavior within the confined interior of carbon nanotubes looking specifically at enhancements in both double layer capacitance and ion transport as well as to develop stimuli-responsive multifunctional membranes for use in breathable and protective fabrics.
