Research in cell signaling and physiology is becoming increasingly important as biophysical techniques progress quickly and merge with molecular biology, biochemistry, and genetics. These developments enable scientists to examine molecular activities within the broader context of cellular and organelle behavior, as well as tissue, organ, and whole-organism functions. Furthermore, incorporating mathematical modeling into this work offers valuable perspectives on how collective actions of ion channels, pumps, and signaling networks shape cellular responses, and how cell groups collaborate to influence complex tissue functions like those in the brain.
At Berkeley, biophysics research explores areas such as ion channel and transporter functionality, protein signaling in cell division and growth, muscle contraction mechanisms, neural secretion, synaptic plasticity, and membrane dynamics involved in secretion, repair, and organelle signaling. The Biophysics Group excels in creating and applying innovative optical and chemical techniques for real-time, high-resolution tracking of protein activity and signaling molecules within specific cellular regions of living tissues. Studies aim both to uncover biological processes and to pioneer genetic treatments for conditions like cystic fibrosis, muscular dystrophy, and retinal disorders. Additionally, Berkeley is making strides in synthetic biology as understanding of cellular signaling and physiology expands.
