OVERVIEW

Biophysics

Biophysics interfaces physics with biology and medicine and is one of the most rapidly developing areas of physics. Because of their specialized training and knowledge, physicists have made major contributions in revealing the secrets of life and in the treatment of disease. These contributions are of great value to humanity. Moreover, biophysics provides challenging research opportunities for physicists.

Physics has contributed greatly to biological science both through conceptual advances and through the development of special techniques for studying matter, including X-rays, NMR, synchrotron and laser light sources, to name a few. Physicists have also been leaders in providing the conceptual framework for understanding both interactions among biological molecules and the way in which these interactions affect living systems. Biophysics draws interest also because biological macromolecules and macro-assemblies are a source of novel physics, and because bio-materials are beginning to find application in technological problems.

High Energy Group

City College has a strong and active research group in atomic and molecular physics. Research in this field has led to the understanding of atomic and molecular structure and interactions. In addition, atomic physics has provided a testing ground for fundamental theories such as quantum electrodynamics and unified gauge theories of the electro-weak interaction.
 
The central objective of all particle physics research is to understand the fundamental interactions of the basic forms of matter and their ultimate structure. The high energy theory group's activity centers on a quantum-field-theoretical study of these interactions, with specific emphasis on gauge field theories, which are indispensable for the description of all interactions.
