Position: Postdoctoral Research Associate Description: The Iain McCulloch research group in the Andlinger Center for Energy and the Environment at Princeton University is seeking applications for postdoctoral research associate(s) or more senior research position(s). The McCulloch group's research involves elucidating new structure property relationships in the design of semiconducting materials for use in applications such as electrochemical transistors, solar fuels, and photovoltaics. The researcher will carry out experimental research in the broad area of ion separations. Responsibilities may include characterization of water uptake, ion sorption, and/or ion transport in polymer membranes and sorbents, synthesis of charged polymer membranes, development
