Educated to post-doc in theoretical chemistry after a PhD in in experimental chemistry.

Now retired from a career mainly in operations-research-related roles with interests in scenario writing and system-dynamics modelling.

Aiming to refresh and extend early interests in physics, theoretical physics and cosmology.

More generally, also to broaden & deepen my mental world-model, especially in relation to socio-economic and political organisation, conceiving the inhabited world(s), fundamentally, as nested complex-adaptive systems.
