======================

I study the loop between social systems and the people inside them: systems shape people, and people reshape systems. And what I cannot simulate, I do not understand.

Currently, I focus on building the science of social simulation:
(i) why it matters (SimThought) → (ii) how to evaluate (HugAgent, SSA) → (iii) how to build (ongoing).
