Experience

  • Scorecard for Credit Worthiness
    https://tymit.com

    A high dimensional model developed in Python to consume data from credit bureaus, such as Experian, combined with mined behavioral features to provide a risk of default score to each applicant. The model is tuned according to the company's KPIs, deployed, and currently in use in production.

  • Atomic Image Reconstruction Using Neural Networks

    A Python module created to construct high-resolution atomic imagining from electron wave functions. A trained neural network is used to fit as closely as possible to wave functions. The subsequent functions are using alongside PyQSTEM to reconstruct very high-resolution images.

    It was published in ACS Nano.

  • Detecting DNA Translocation Signal
    https://iopscience.iop.org/article/10.1088/1361-6463/abe07b

    DNA strands moving through a hole and pore can create electrical signals that can be used to sequence the base pairs present. However, these signals are weak and significantly weaker than the overpowering random noise. Signal analysis techniques and clustering algorithms are used to unpick signals from noise and identify different lengths and composition of DNA present in samples.

    It was published in IOP.
