After finishing undergraduate studies, I worked as a science journalist for outlets including Science, the Washington Post, Wired, and Mother Jones. In 2005, I produced an award-winning documentary for CNN. After finishing graduate school, I taught at Carnegie Mellon University for several years, including courses on survey design and human rights documentation. I also supervised student research projects and managed relationships with community partners. At the University of Washington, I combine the my technical and communication skills to teach scientific and statistical methods to students from a range of backgrounds.
