Primary Research Areas

• An Agent-Based Test Bed for Restructured Wholesale Power Markets

• Agent-Based Computational Economics (ACE)

• Flexible Least Squares (multicriteria estimation)

• Adaptive Computation Methods for Nonlinear Systems (nonlocal sensitivity analysis, eigenvalue/eigenvector tracking, automatic differentiation, adaptive homotopy continuation)

• The Trade Network Game Laboratory (endogenous network formation through choice and refusal of game partners)

• Optimality and Efficiency in Open-Ended Dynamic Economies (e.g., First Welfare Theorem for overlapping generations economies)

• Learning via Criterion Filtering (temporal-difference/Q-learning)

Current Research Topics

• Testing the efficiency and reliability of restructured wholesale power market designs
