I received a PhD in analytical chemistry in Sep 2005, completed postdoctoral research in Jun 2007, and taught chemistry survey and organic chemistry from Sep 2009 - May 2010. I am currently a freelance technical science editor. Phased presents science journalism written for a lay audience. My goal is to discuss technical content (from the technical journals) without sacrificing readability. The topical focus is diverse, but tends to focus on chemistry, technology, and cell biology.
