This Week in Virology

twiv

This Week in Virology (TWiV) is a podcast – or netcast, as some prefer to call them, since you don’t need an iPod to listen – about viruses. It was begun in September 2008 by Vincent Racaniello and Dick Despommier, two science Professors at Columbia University Medical Center. Their goal was to have an informal yet informative conversation about viruses which would be accessible to everyone, no matter what their science background. We wanted to eventually bring other virologists into the conversation, to make it more varied and interesting. Alan Dove, a science writer, joined us late in 2008, and Rich Condit, a poxvirologist, joined in 2009. We’ve had a number of guests on the show and we’re always trying to get more.

Why are we doing this? Dick, Rich, and I have spent our entire academic careers directing research laboratories, so we have a lot of knowledge to share. Plus, we both enjoy teaching. Put those two things together, and you have TWiV. If you want to learn about viruses in a relaxing way, then TWiV is for you.
