Human Decision Making Process Modeling

Dynamic Bayesian Inference Network

measurement + latent inference + dynamic modeling

I was trained in Bayesian inference network modeling under the Evidence-Centered Design framework with Robert J. Mislevy and Russell G. Almond, and my doctoral work developed dynamic Bayesian network models for longitudinal psychological inference that integrate latent psychological measurement, causal inference, and intervention modeling

Building on this foundation, my current work integrates psychometric latent state modeling with causal and decision-theoretic Bayesian networks to move beyond static prediction toward interpretative, intervention-relevant systems.

Early work: dynamic Bayesian inference for latent psychological states
Field shift: causality + decision science
Current work: unifying measurement + dynamics + intervention modeling
