Research Interests:

Our lab uses a set of interdisciplinary approaches to examine molecular events in cells and piece them together, using computational models, into quantitative models of cellular behavior. We use a range of biochemical, microscopy and spectroscopy-based techniques to investigate protein function through complex formation, dynamics and localization in living cells. These data are then put together into kinetic computational models that attempt to approximate specific cellular functions and used to predict novel behaviors in silico.

Specifically, the lab utilizes engineered mammalian cell lines and those derived from transgenic mice to provide unique intracellular contexts to probe protein function. Much of the information for protein function is derived from live cell measurements, either through simple widefield fluorescence microscopy or fluorescence correlation and lifetime techniques that yield quantitative interaction data.

We are currently focusing on three major cell biology areas in which to apply our interdisciplinary approach: (1) the mitotic checkpoint - a biochemical and biophysical signaling network that prevents untimely chromosome segregation, (2) intraflagellar transport - a cellular network that builds and maintains tubulin-based structures such as cilia and flagella and (3) synthetic genetic networks - engineered genetic circuits that allow us to probe fundamental molecular mechanisms in transcription and translation.
