Abstract: My talk will focus on the new frontier in soft matter physics -- collective assembly and dynamics of active building blocks, whose properties we can design and regulate experimentally. We introduce the mechanism of energy conversion and communication for individual constituents in both synthetic and biological materials, so the assembly structures and dynamics are distinctly different from and much more exciting than traditional equilibrium assembly. Advances in understanding of such active systems may lead to understanding of complex physical behavior in living cells and designing of biomimetic micro-robotics. About the speaker: 张洁，2011年从科大化学系本科毕业，获郭沫若奖学金。赴美国伊利诺伊大学香槟分校材料系攻读博士学位，师从美国国家科学院院士Steve Granick，致力于交叉学科的新型软物质材料设计及其统计物理性质研究。博士毕业后加入加州大学圣巴巴拉分校物理系教授Zvonimir Dogic实验室，将研究方向扩展到活性生命材料的物理特性研究当中。研究内容涉及物理、化学、工程等多个学科，在多个国际会议上得到了相关领域同行的广泛认可（包括美国物理学会年会、戈登研究会议、美国化学胶体与表面化学会议等）。
