In my Astronomy research, I am primarily interested in how the gas in galaxies constantly re-arranges itself over huge time spans to constantly form new stars. I have also had a long-standing interest in data visualization, and in improving the use of computers in all aspects of scientific research. I teach a course at Harvard called "The Art of Numbers," and I am very involved in the WorldWide Telescope Project, which brings astronomical data to everyone through an interface that demonstrates data delivery for the 21st Century of "e-Science."

The COordinated Molecular Probe Line Extinction Thermal Emission Survey of Star-Forming Regions is a large collaborative study of the star-formation processes in Perseus, Ophiuchus and Serpens, across the electromagnetic spectrum.
Seamless Astronomy Icon
Seamless Astronomy
brings together astronomers, computer scientists, information scientists, librarians and visualization experts involved in the development of tools and systems to study and enable the next generation of online astronomical research.

Universe3d  icon
Universe 3D
At present, this site collects information about tools and data that allow us to understand the 3D structure of the Solar System, the Milky Way Galaxy, and the Universe. In the future, the site will link tools and data within an environment that can be used to "see" the Universe's 3D structure.

Dataverse  icon
Astronomy Datavere
( is is a prototype Astronomy data repository. The project is a collaboration of the Seamless Astronomy group at the Harvard-Smithsonian Center for Astrophysics, the ADS, the Wolbach Library, and IQSS with support from the Harvard Library.
Vizelab icon
A place where researchers develop and test new visualization and e-Science approaches in research and education. Use is open to members of the Center for Astrophysics community.
WWT icon
WorldWide Telescope Ambassadors
The WorldWide Telescope computer program (WWT) from Microsoft Research is a free tool offering immersive views of the sky and multimedia links to interactive descriptions and explanations of millions of celestial objects. WorldWide Telescope Ambassadors use WWT to educate the world about Astronomy and Science.
Astronomical Medicine icon
Astronomical Medicine
The goal of the Astronomical Medicine (AM) project is to extend the state of the art of complex data understanding in two very different fields, astronomy and medical imaging, using a broad-based approach to data exploration and analysis.

Taste Tests icon
Star Formation Taste Tests
Since inputs and included processes in numerical simulations are adjustable, synthetic observations of simulations can be thought of as "controlled" experiments on how stars might form. "Taste-testing" is the effort of statistically comparing the synthetic observations of star-forming regions with real ones.
