In my astrophysical research, I am primarily interested in how the gas in galaxies constantly rearranges itself over huge time spans to constantly form new stars, and in bringing large data sets and new data science techniques to bear on understanding the structure of the Milky Way. I have also had a long-standing interest in data visualization, and in improving the use of computers in all aspects of modern (21st century) scholarship and scientific research. My interests in astronomy, visualization, and 21st-century tools combine in the form of WorldWide Telescope, which I help create and maintain, and upon which the WorldWide Telescope Ambassadors science education Program I founded often relies. Since 2014, I have become very interested in the history of Prediction, as a way to understand modern computer simulations and their interpretation. I have served as coDirector for Science, where I help to bring new scholarship across the sciences to the attention of scholars and the public, at Radcliffe since 2017. Someday soon, I may perhaps find time to make custom webpages for each of my interest areas below, but for now, please do follow the links, as many of the projects have entire websites of their own.
Presentations associated with all of the projects below can be found at the Talks Page.
