EXPERIENCE
08/07 – present Contract consultant, Center for Health Services Research at Henry Ford Health System, Detroit, MI.
  • Developed an enhancement to a widely-used GPL human-genetics research modeling software to extend the model from individuals to pedigrees. The peer-reviewed paper for the enhancement is not yet published.
    • Created lexical analyzer and parser for pedigree files and various other input files.
    • Created various graph representation, traversal, manipulation structures and algorithms.
    • The low-level state-transition modeling uses a Hidden Markov Model to evaluate likelihood of a given set of observed genotyped inputs and modeled parameters.
    • The higher-level statistical modeling uses the Metropolis-Hastings algorithm to refine the modeled parameters to better fit the data via a random walk sampling.
    • Extremely computationally intensive; I implemented concurrent shared-memory execution using OpenMP.
  • Developed epidemiological research system:
    • Utilized by the SAPPHIRE study.
    • Implemented using Qt, PostGreSQL
    • Platform-independent GUI front-end, runs on Linux, Windows, or OS/X
    • Participant tracking, participant surveys, integrated database with pulmonary function and other medical record data, sample tracking.
