The Tucker-Kellogg Lab at Duke-NUS works on wound healing and computational modeling. The wound healing side of the lab studies how muscle tissue is injured and repaired, and our main experimental approaches are microscope imaging of endogenous regeneration, and molecular assays of cells in vitro. The majority of this work is "wetlab" although it does include computational image analysis and computational modeling. The computational modeling side of the lab studies a variety of biological problems provided by experimental collaborators, as well as the wound healing problems provided by our own experiments. Computational modeling allows us to take a series of snapshot measurements, whether from images or molecular concentrations, and infer something indirectly about the underlying dynamic mechanisms that might give rise to the observed time-point measurements. This use of modeling to "connect the dots" of experimental data is particularly relevant to studying the up-and-down dynamics of cell signaling, or the flow of nutrients through metabolic networks.

Lab Overview

We build computational models that are tailored to specific biological questions, and we carry out experimental tests of model-based predictions, in collaboration with experimental and clinical collaborators.

Biological Questions

  • Cell behaviors during injury response & oxidative stress.
  • Extracellular signalling and post-translational signalling.
  • The organization of spatially-specific and temporally-specific signals during injury response.

Computational Methods

  • Quantifying the trends and slopes for temporal and spatiotemporal effects.
  • Ordinary differential equations (ODEs) describing temporal effects, computed repeatedly over space.
  • Bayesian network models and probabilistic networks, for poorly-understood chains of causal influence.
  • Quantifying relationships between cell morphology and biological function, (collab with bioimaging).
  • Custom built models (ball and stick, spring and dashpot, or autonomous agents following rules).
