WELCOME

I'm Dr. Andrew Marsh, a software developer who originally studied architecture, but whose driving passion is building performance analysis and simulation. This is a personal website that I use as an on-line notebook and platform for some of my experimental web-based apps, as well as various musings on building performance, web development, computer programming, generative design and 3D visualisation.
