Publications

  • On Oversampling Imbalanced Data with Deep Conditional Generative Models

    Expert Systems with Applications

    Other authors

  • Waiting Time Distributions in the Preemptive Accumulating Priority Queue

    Springer - Methodology and Computing in Applied Probability

    Analyzed a preemptive priority queue in which customer priority levels accumulate linearly throughout time. Developed a recursive procedure to obtain the marginal waiting time distributions.
    (Python, Maple, Mathematica)

    Other authors
    • Steve Drekic
    See publication

  • Controlling the workload of M/G/1 queues via the q-policy

    European Journal of Operational Research

    Other authors
    • Steve Drekic
    See publication

  • An M/G/1 Queue with Customer Blocking

    Analyzed the effects of implementing a new customer blocking policy on several performance measures of a classical queueing system.
    (Python, Maple, Mathematica)

  • On a General Mixed Priority Queue with Server Discretion

    Designed and analyzed a general priority queueing system to understand the wait times for patients arriving to an emergency department of a hospital.
    (Python, Maple, Mathematica)

  • A Least Square Method on Confidence Regions for High Quantiles of Heavy Tailed Distributions

    Developed a new high quantile point estimator for heavy-tailed distributions, and used asymptotic methods to obtain its approximate confidence region.
    (Mathematica, Maple)

Projects

  • A Generalization of M/G/1 Priority Models via Accumulating Priority

    Focused on the design and analysis of accumulating priority queueing systems. Mathematical expressions for waiting time distributions were established, and were confirmed via computer simulation.
    (Python, MATLAB, Mathematica, MAPLE)

    See project

  • Billion Dollar Project Part II – Predicting March Madness

    Used non-linear statistical learning methods to create a general framework for predicting outcomes in the March Madness tournament. The overall method displayed high accuracy in predicting the 2015 NCAA tournament.
    (SQL, Python, R)

  • Billion Dollar Project – Predicting March Madness

    Used generalized linear model techniques to obtain estimated probabilities of outcomes in the 2014 NCAA Men’s Division 1 Basketball tournament. Predicted all four No.5 vs. No.12 games correctly. (Python, R)
