Incorporating anisotropy here is of general interest, for example in actin networks, clay platelets, and polymer nanocomposites where geometry, ordering, and kinetics all play important roles in determining their properties. Nevertheless, forming a general connection between microstructure and macroscale properties is not trivial. Here, I focus on the self-assembly and mechanics of colloidal materials with an emphasis on how shape anisotropy and interaction potential can be used to guide their design. I will first discuss the relevance of the physical interactions that give rise to a general class of colloidal gels. Then, I will introduce structural rigidity in the context of gels undergoing large deformations, and how shape anisotropy can introduce unusual states through kinetic trapping. Lastly, I will show that the slowed rotational dynamics caused by surface roughness can lead to enhanced shear thickening that is not seen with smooth colloids. These results collectively show that particle-level interactions provide a powerful means to design soft materials at multiple length scales.<o:p></o:p></p><p class=MsoNormal style='text-align:justify'><span style='font-size:14.0pt;font-family:"Times New Roman","serif";color:black'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify;background:white'><span style='font-family:"Cambria","serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><b><u><span style='font-size:14.0pt'>BIO: </span></u></b>Lilian Hsiao is currently a Postdoctoral Associate in Chemical Engineering at the Massachusetts Institute of Technology.
