The research in the Rubinstein Group is in the field of polymer theory and computer simulations. The unique properties of polymeric systems are due to the size, topology and interactions of the molecules they are made of. Our goal is to understand the properties of various polymeric systems and to design new systems with even more interesting and useful properties. Our approach is based upon building and solving simple molecular models of different polymeric systems. The models we develop are simple enough to be solved either analytically or numerically, but contain the main features leading to unique properties of real polymers. Computer simulations of our models serve as an important bridge between analytical calculations and experiments.
Research in the Wightman Group is directed at the development of microsensors and their use to measure chemical events in microenvironments. We have developed ultramicroelectrodes that are robust chemical sensors, which can resolve chemical events with micron or submicron spatial resolution. In addition, these probes can be used for measurements on the nanosecond time scale and in environments in which electrochemical measurements are normally impossible.
