Penn Summer Science Academy in Experimental Physics

PSSA - Experimental Physics is a four week program that focuses on modern physics with an emphasis on hands-on experience and laboratory work. There is no requirement of a previous physics course, although typically about half of our students have taken one prior to attending PSSA.


Master of Medical Physics

The Department of Physics and Astronomy in the School of Arts and Sciences, in conjunction with the Departments of Radiology and Radiation Oncology in the School of Medicine, offers the Master of Medical Physics degree. The program is intended for technically prepared college graduates who seek to combine their interests in graduate physics with growing career opportunities in the field of medicine.


Bio-optics and bio-optical materials

Prof. Alison Sweeney and her colleagues believe that the reflective structures in giant clams help them grow algae. The clams use sub-wavelength structures formed from a protein called reflectin to optimize the photosynthesis of the algae living in the clam tissues.

Functional Imaging in the Brain

A representation of blood flow changes in a rat brain during cortical spreading depression. In the experiment, a large local concentration of KCl initiates a 'wave' of neuronal depolarization that propagates outward from a central point and then repeats itself.  The figure shows images of blood flow in four parallel planes located within 3 millimeters of the skull.


Premelting of Colloidal Crystals

Premelting is the localized loss of crystalline order at surfaces and defects at temperatures below the melting transition.  This result is from the lab of Prof. Arjun Yodh.
