David Rittenhouse Laboratory - Walnut Street view

DRL is the academic home of the Mathematics and Physics and Astronomy departments at Penn.  It is named for David Rittenhouse, a noted American astronomer born near Germantown, Philadelphia.  Rittenhouse was one of the first to build a telescope in the United States and was Professor of Astronomy at Penn starting in 1779.



Professor Bob Hollebeek was the technical lead for the National Library of Medicine sponsored National Digital Mammography Archive, which provides distributed grid systems for medical storage and records handling.  Parallel and distributed computing approaches apply to the analysis of data from many fields including medical, scientific, social, and economic data.


Sudbury Neutrino Observatory

The Sudbury Neutrino Observatory (SNO) is a second generation dedicated solar neutrino experiment which has extended the results of the Penn group with the Kamiokande II detector by measuring three reactions of solar neutrinos to fully resolve the solar neutrino problem.


Two-Dimensional Foams

The evolution of foams in 2 and 3 dimensions has interested theorists and experimentalists for decades. Professor Doug Durian's group is developing apparatus to test theoretical laws on coarsening of foams on planar and curved surfaces.
