Cells rely on complex signaling networks to sense and respond to environmental stimuli, but the bigger picture of how molecular assembly leads to robust cellular signaling is only beginning to emerge. A major challenge in characterizing cellular signaling is the ability to directly observe the dynamic interactions between membrane receptors and intracellular signaling partners in living cells. To address this challenge, this work presents the development of advanced fluorescence imaging and computational analysis tools designed to improve the precision and quantitative power of live-cell micro-spectroscopy for studying protein dynamics in real time.
