My handle refers to my accent: mostly southern US, with some hints of British—enough for people to ask me about it. I attended medical school and did my residency on the US east coast. Recently I completed a fellowship.
While I hope that Wikipedia won't decline, problems with it have been covered in the October 22, 2013 MIT Technology Review: The Decline of Wikipedia and elsewhere online.

My main purpose for writing here was to make the Schizoaffective disorder article better, because many patients and their families couldn't find good, solid information on the disorder. Schizoaffective disorder has been neglected by psychiatry and is only now beginning to be researched in much more depth using advanced technologies like genetics and neuroimaging (which my research team has been working on). Psychiatric disorders in the future will be seen less as distinct individual disorders, and much more as overlapping phenomena, as recent genetic research has shown.
