    • Designed and developed a small diameter hydrogel-based vascular graft that is highly biocompatible, reduces significantly the risk of thrombosis, and increases the patency once placed within patients.
    • Conducted various mechanical testing and reached the final design of poly(ethylene glycol) diacrylate (PEGDA)-clay nanocomposite hydrogel, which showed robust mechanical properties that can be controlled by varying clay concentrations.
    Molecular Systems and Gene Regulation Group, Nanoengineering, UCSD – 2008 - 2010

    • Built a computer model to simulate random walks of transcription factors in the presence of various conformations of compact chromatin fibers using C++.
    • Performed kinetic Monte Carlo simulation, which revealed different modes of diffusion that transcription factors undergo: 3D-diffusion, when they are far away from DNA/chromatin fiber and 1D-diffusion along the DNA, otherwise.

    • Developed the Biochemical, Genetic and Genomic (BiGG) knowledgebase, which provides the first collection of curated, high quality metabolic reconstructions.
    • Integrated metabolic flux constraints as well as objective functions required for mathematical optimization to various organisms’ genome-scale metabolic reconstruction models.
    • Rendered respective organisms’ metabolic networks in Scalable Vector Graphics (SVG) that can be interactively displayed in web browsers using Perl and SQL.
