Computational Soft Matter and Biophysics Group

@ City University of Hong Kong

  • We apply multi-scale modeling, from atomistic to coarse-grained, and statistical mechanics to perform research in soft matter physics and biophysics, with tight collaboration with experimental groups.

  • In addition to addressing fundamental physics problems in soft matter systems, our group is interested in practical applications such as design of antimicrobial peptides for antibiotic drugs, and DNA sequencing technologies based on nanopores or nanochannels.

GE1305 Everyday physics

In this course, a non-mathematical approach is used to teach students physics concepts and principles, which are of general relevance and enable the students to develop well-informed opinions and choices in their professional career and everyday life. Students are also expected to learn in the course thinking skills of a physicist, which are evidence-based, critical and based on the framework of physical principles.

PHY1400 - Introductory Physics for Biologists

This course covers a wide scope of topics in physics relevant to medical and veterinary programs including biomechanics, heat, gases, wave and optics in both physiological and pathological contexts.

PHY8001 Survival skills for research scientists

The course is designed for students enrolled in the MPhil and PhD programmes to train them in acquiring the necessary skills of practicing research scientists.

PHY8004 Postgraduate Seminar

The course aims to broaden the scientific horizon of postgraduate students in the fields of physics via active participation on research and scientific seminars. This course is a scientific forum for postgraduate students to exchange research information and to discuss scientific problems. The course is designed to develop the communication skills at presentation of research and scientific work.

PHY4274 Radiation Biophysics

The present course aims to teach the students about the correlations of radiation physics and behavior of the human body. The course materials mainly cover the interactions of ionization radiation with cells and tissues in the human body, and clinical applications of ionizing radiation.
