Asst Prof Ni Ran
Assistant Professor, School of Chemical and Biomedical Engineering
Assistant Professor, School of Physical & Mathematical Sciences
|Dr. Ni received his B.S. (2005) in Computational Mathematics and M.S. (2008) in Chemical Engineering from Beijing University of Chemical Technology. From 2008 to 2012, he did his Ph.D. in Physics with Prof. Marjolein Dijkstra in Utrecht University (the Netherlands) focusing on the computational study on the self-assembly of colloidal systems. From 2012 to 2014, he did his postdoc with Profs. Martien A. Cohen Stuart and Peter G. Bolhuis focusing on the self-assembly of fibril-forming polypeptides. In 2014, he was awarded the NWO VENI fellowship which is the most prestigious personal grant for young scientists in the Netherlands to start independent research. In March 2016, he joined the School of Chemical and Biomedical Engineering in Nanyang Technological University as an assistant professor.|

|The concept of "soft matter" was first introduced by Pierre-Gilles de Gennes in his Nobel lecture in 1991. Essentially, soft matter is a subfield of condensed matter comprising a variety of physical systems that are deformed or structurally altered by thermal or mechanical stress of the magnitude of thermal fluctuations. Because of their responsivity with respect to perturbations, e.g. thermal fluctuations, mechanical deformation, external fields, etc., soft matter have shown great promise as the next generation “smart materials”.|
In our group, we use computer simulation as a tool to study and predict the structural properties and dynamic behaviour of soft matter systems in and out of equilibrium to direct the experimental fabrication of functional materials. In particular, we are interested in the self-assembly of colloidal and (bio) polymer systems and work synergically with experimentalists to design new functional materials with application in photonic devices, bio-sensor, bio-materials, etc. Presently, we are interested in the projects below:
1. Dynamic assembly of active matter
2. Glass transition of anisotropic colloids
3. Hierarchical self-assembly of anisotropic colloids
4. Self-assembly of fibril-forming polypeptides
- Designing flexible colloidal clusters by using DNA coated particles
- Dynamic hyperuniform materials
- Hierarchical assembly of colloidal super crystals
- Self-assembly of colloidal functional materials
