Current Research
  • Cooperative bio-inspired Optimization: Using the process via which ants optimize their trails when traversing previously unknown terrain, we are exploring a progression of optimal control problems involving a collection of control systems which are attempting to discover optimal trajectories via pair-wise cooperation among neighboring agents.

  • Optimization of Tax Policies: This work is aimed at developing MDP-based models of the process via which economic agents (e.g. small businesses or corporations) make tax-related decisions, including whether or not to keep from disclosing income, where conditions allow. The goal is to arrive at a set of tools for evaluating tax policy and for examining the effects of proposed changes in the tax code, before they are adopted.

  • Economy & Environment: As concerns over global warming, pollution and resource usage keep mounting, the economy's environmental footprint is becoming an increasingly important consideration. The goal of this work is to examine a series of optimization problems which connect economic production, pollution, energy, and economic growth, and to develop computational decision-making tools which are informed by empirical data.

  • Detection and Evaluation of Parkinson's Disease in Drawing patterns: The goal of this work is to produce metrics for measuring the presence or progress of Parkinson's disease based on hand-drawing patterns measured via writing pads and/or accelerometers.[In cooperation with Aristotle University]
