Reflective Self-Assembling Proteins

Prof. Alison Sweeney studies the biophysical properties of reflectin - a highly reflective and self-organizing squid protein found in cephalopods like the Hawaiian Bobtail squid shown here.


The Best View in Philadelphia

The University of Pennsylvania recently finished their newest addition to the campus, Penn Park, which adds a brilliant contrast to the Philadelphia skyline and gives multiple sports teams a new place to practice and engage in athletics.

Large Hadron Collider - ATLAS Higgs candidate event

An event captured by the ATLAS detector in the search for a Higgs boson decaying into two Z bosons, one of which goes into a pair of electrons and two muons (the two tracks shown in red). There is no way to tell if this particular event comes from a Higgs decay or simply from a background event such as one containing two Z bosons.


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.



Prof. Vijay Balasubramanian's research includes studies of structural and functional organization of the retina with multi-electrode arrays that record retinal ganglion cells. He also studies computational principles that underlie the organization of circuits in the early visual system.
