Neuroscience

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.

Majorana Fermions, Topological Insulators and Superconductors

Magnetic diffraction pattern for a Josephson junction with a topological insulator weak link. Building on a theoretical description published in 2008 by Prof. Charles Kane and Liang Fu at Penn, Stanford researchers believe the unusual behavior is explained in terms of Majorana fermions.

DES First Light

One of the first images from the DECam (the half-gigapixel camera of the Dark Energy Survey) showing the barred spiral galaxy NGC 1365. Penn faculty and staff play a prominent role in leading the DES effort.

LaBr3 detector modules for Next Generation PET scanners

On the left is a schematic of adjacent modules with overlapping photomultiplier tubes while the right is a photograph of a single module with PMT's and 8-mm thick light guide.  Improvements in timing resolution for time-of-flight PET is the research of Adjunct Prof. Joel Karp in Penn Radiology.

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.
