Alexander S. Szalay Cosmologist

Alexander Szalay works on the spatial distributions of galaxies and galaxy formation. He is currently building a parallel database engine and is leading a grass-roots standardization effort to bring the next generation Terabyte-sized databases in astronomy to a common basis, so that they will be interoperable. He is the architect for the Science Archive of the Sloan Digital Sky Survey (SDSS), the most ambitious astronomical survey project ever undertaken, and has designed the software to perform data mining on the SDSS Terabyte sized archive, based on innovative spatial indexing techniques.
