I'm a deeply committed tech head who's been playing with a broad range of AV technologies since well before there was something called AV.  I love to know how and why things work, and stumbled on the fact that I have a talent for explaining what I've learned, so I've been teaching and writing about all kinds of technologies for a while now.  I've worked in AV, broadcast, live production, IT, publishing, consulting, and events. Over the last five years I've written the new editions of the CTS, CTS-I, and CTS-D Exam Guides. The most fun part of what I do is research into developing technologies to see how they fit into the future of AV and IT.  I'm presently heavily involved in initiatives to improve the sustainability of the technologies we use in the audiovisual industries.
