In biological physics, quantitative aspects and ideas and techniques of physics research are applied to biological problems. Physics has been evolving in the direction of studying more complex systems, and in doing so, has begun to expand its subject area to include living systems.
Biophysics is an interdisciplinary science that uses the methods of chemistry and physics—among others—in order to study biological systems. Biophysicists conduct research concerned with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis, as well as how these interactions are regulated. The The School of Physics and Astronomy works collaboratively with other departments across campus in order to conduct research in this field.
