At the scale of single molecules such as DNA, RNA, and molecular motors, research in our area focuses on issues in protein synthesis, such as how ribosomes move along mRNA. At the sub-cellular level, research explores photosynthesis and the properties of cell membranes and membrane proteins. And at the scale of individual cells, we investigate phenomena like signaling and locomotion. Multi-cellular dynamics, pattern formation, and the physics of evolutionary processes are also key components of our program.
Experimental methods include optical tweezers, single-molecule fluorescence microscopy, particle imaging velocimetry and image processing, and a variety of techniques in molecular and cellular biology and biochemistry. Theoretical work focuses on stochastic processes, elasticity, statistical mechanics, fluid dynamics, and nonlinear dynamics. Our theoretical and experimental groups also actively collaborate with faculty in the life sciences throughout the University of Arizona.
Biological Physics studies "the Physics of Life Processes" by applying the quantitative physical sciences approach to outstanding problems in Biology while also feeding crucial insights thus obtained back into Physics.
