Dr. Thomas Truskett an assistant professor in the Department of Chemical Engineering at The University of Texas at Austin has discovered how to predict the mobility of confined fluids at nanometer scales.  The ability to predict these changes has applications in fields such as cell biology and geophysics, as well as important implications for the design of nano-scale devices.
