I am a Canadian currently working in the US. I did my medical school and residency training (in Ophthalmology) in the US. I just finished a Glaucoma Fellowship (graduated July 2007), so I feel pretty confident contributing to the entries on glaucoma and ophthalmology in general. I am rather new to Wikipedia, and am still learning the editing techniques. I have a good deal of experience writing for books, review articles and original science papers. I have an interest in general Ophthalmology clinical work (and research stemming from it), and basic research.
I hope to contribute to a number of articles, and improve the references for many since I've had to look up the original references to do the books/articles.
