Annette Greiner is a user experience designer and data wrangler with particular interest in data visualization. She came to NERSC upon completion of a Master's in Information Management and Systems from UC Berkeley's School of Information, with a focus on human-computer interaction. Before returning to school, she developed web sites for the Advanced Light Source and the DOE Joint Genome Institute. At NERSC, her duties include understanding user needs in context and ensuring that users can efficiently advance their science goals by using NERSC resources. At a broader level, she represents the Laboratory to the World Wide Web Consortium (W3C) and has served on international working groups related to publication and sharing of data. Her interests touch the UC Berkeley campus as well, where she developed and taught for several years the data visualization course for the Master's in Information and Data Science (MIDS) program at the School of Information. Annette also holds a B.S. in biomedical science and theater from the University of Michigan. She was a founding member of Chicago's Theater Oobleck.
