lead developer · released vbpca-py Variational Bayesian PCA for incomplete data with full posterior uncertainty, calibrated predictive variance, automatic component pruning, native missingness handling, and C++-accelerated kernels. trade-study Design and evaluation framework for scientific simulation studies. Score competing configurations — model formulations, solver choices, measurement strategies, or any design decision — against known ground truth via protocol-driven simulators, proper scoring rules, hierarchical phases, multi-objective Pareto optimization, and Bayesian model stacking. lead developer · in development OP Engine Operator-partitioned ODE/PDE solver core with nine integration methods (explicit, IMEX, fully implicit), adaptive step-size control, and zero per-step allocation. OP System Declarative specification language and compiler for structured dynamical systems. Two specification pathways, multi-axis stratification, and compilation to validated bytecode closures. pp-eigentest Posterior predictive eigenvalue testing for signal rank determination. Three-layer consensus architecture with FWER and FDR control; NumPy, C++, JAX, and sparse backends. collaborative infrastructure FlepiMoP2 Configuration-driven orchestration engine for CDC-supported infectious disease forecasting and scenario analysis. Plugin architecture decoupling model specification, integration, and persistence.
