I have invited Sheril Kirshenbaum, who did such a spectacular job blogging here in my absence a few weeks back, to come on to blog here permanently. And she has accepted. "The Intersection" will thus become a two person blog....and all of you will be regaled regularly by Sheril's awesome and unique blend of science and pop culture commentary. I'm not sure I really need to introduce Sheril much more fully at this point. But for those who may have been on, say, the Andaman Islands for the last few weeks, I'll do so again briefly. Sheril is an associate at Duke's Nicholas Institute for Environmental Policy Solutions who specializes in ocean and coastal policy, and who worked on Capitol Hill in the office of Florida Senator Bill Nelson. Not only is Sheril trained in marine biology; she also has experience in pop radio. As for technical details: Sheril posts whenever she wants, and so do I. Not very tough, eh? Very soon she will be posting under her own name once we get various technical details sorted out. For the time being, you may see a few more posts of hers that are technically under my name. And that's it for housekeeping...I hope you all will welcome Sheril to "The Intersection"...permanently this time!
