TTU Physics Department.

Bio Physics


Our TTU Bio Physics consists of Professors Cheng and Huang. We are working on a variety of biological physics problems such as membrane cholesterol organizations, lipid rafts, protein folding, and cellular mechanics related with adhesion, microrheology, and motility.
Our group has major fabrication, spectroscopy, imaging and computation facilities to study a multitude of biological systems ranging from single Alzheimer peptide, fingerprints, quantum dots, lipid superlattices, liposomes, organic funtionalized mesoporous silica and cells.
Our results will provide fundamental knowledge of the physics underlying the function-structure-dynamics relationship of cell membranes and proteins, neuroscience, protein aggregation diseases, heart diseases, ultra-sensitive chemical sensors and cellular mechanotransduction for modern tissue engineering.
Currently, our group has seven PhD students, one master student and three undergraduate students.
