- Using information theory to understand interaction between genetic sensors and cells.
- Simulating polymer network growth with stochastic reaction-diffusion kinetics.
- Determining properties of disordered networks using effective medium methods.
The engineering biology team at NIST is working to enable predictive engineering in synthetic biology. I am contributing in this direction by developing computational tools for: (a) simulating the interaction between genetic sensors and cells to study the efficiency of signal transduction, and (b) determining mutual information and other information theoretic quantities from widely-used experimental measurements (e.g. flow cytometry).
The 2nd and 3rd projects are part of NIST’s mission to accelerate materials innovation for the objectives of the Materials Genome Initiative. Specifically, I am developing methods to simulate polymer network growth as a stochastic process governed by the reaction-diffusion master nist-equation. Using this method, we can determine the effect of polymerization rate (or curing protocols) on the topological disorder in the network. We further compute the material properties of the disordered network. Thereby, computationally mapping polymerization protocols to transient and end-of-cure polymer properties. More details available on our MGI project site.
