My dissertation is available for download, here. The main focus of my dissertation was on the ErbB family of receptor tyrosine kinases (RTK).  My work included developing mathematical modeling tools, as well as implementing those tools to make predictions about the ErbB family dynamics and kinetics. I believe by using a cycle of experimentation and predictive modeling the efficiency of research and development can be increased exponentially.


  • Developed a spatial stochastic model which utilizes Single Particle Tracking (SPT) data to investigate the dynamics and kinetics of proteins on and near the cell membrane.
    • Validated using SPT data.
    • Predicts protein behavior and interactions beyond current experimental capabilities.
    • Novel experimental methods can then be developed based on predictions made by the model.
  • Created a graphical user interface (GUI) for the model to allow both modelers and experimentalist to utilize the program.
  • Developed an algorithm to estimate the size distribution of domains on the cellular membrane.

Spatial Stochastic Model Applications:

  • Uncovering the mechanism of lateral signal propagation through simulated experiments.
  • Discovering the complex dynamics of ErbB2-ErbB3 and ErbB3-ErbB3 interactions and their impact on signal initiation.
