Hey folks... Dr. Alan Doucette here. I'm a professor of Chemistry at Dalhousie University, in Halifax, Canada. I specialized in chemical analysis, and over the years as a research scientist, I've created several new tools to better characterize biological systems - especially when it comes to protein analysis. I'm also passionate about teaching. So I put these videos together to help my students visualize some of the concepts presented in various analytical courses. I welcome your feedback, and will continue to post new videos that I hope will one day help you in your studies.
