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.


Molecular Electronics

A synthetic peptide candidate that can be used for single molecule electronic measurements.  Single molecules can act as a functioning part of a field effect transistor device as studied in Professor Charlie Johnson's lab.


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.


Euclid Mission to Explore Dark Energy

Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures.  Penn researchers are part of the Euclid science team.


Proteins on Carbon Nanotubes

The image shows an example of peptides that assemble into a tubular structure surrouding single-walled carbon nanotubes.  The geometrically defined, virus-like coating created by these peptides converts the smooth surfaces of carbon nanotubes into highly textured assemblies with long-scale order, capable of directing the assembly of gold nanoparticles into helical arrays along the nanotube axis.
