5tubes.jpgThe unifying research theme of the cf2 group, led by Prof. Matteo Pasquali, is the interaction of flow and liquid micro- and nano-structure. Most engineered materials are formed and/or processed in the liquid state; they are complex fluids because they possess intrinsic length scales that are well-separated from the macroscopic length scales of the process (usually tens of micrometers to meters) and the nanoscopic length scales of the solvent (usually smaller than one nanometer). For example, in polymer solutions and melts the intrinsic length scale is the length of the polymer (usually hundreds of nanometers to few micrometers), which is well separated from the finer length scales (solvent diameter in solution, polymer diameter in melts). The large scale microstructural features relax on timescales that overlap the flow time scales; thus, the dynamic morphology can differ dramatically from the equilibrium one, and this changing morphology affects the flow and produced intriguing nonlinear dynamical phenomena that are not observed in flowing liquids of low-molecular weight. 

We are continuously looking for exceptional researchers to help us make the world a better place through advances in scientific understanding and technological applications.  If you are interested in joining our group as a postdoctoral researcher, please send your CV and a statement of interests to Annie Achim.  If you are interested in joining us as a PhD student, please visit our departmental recruiting webpage here.
