Researchers in the physics department employ experimental as well as mathematical and computational modeling to study the organization and dynamics of biological systems. They are involved in interdisciplinary collaborations with researchers in biology, bioengineering and related fields. Areas of research involve experimental and theoretical studies of mechanical properties of cells and biomaterials using techniques such as optical tweezers and optical microscopy, modeling studies of cell division, cell motion, polarized growth, and mating, physics of cytoskeletal self-organization, and experimental study of lipid membranes using microfluidics and confocal microscopy. The Ph D program includes a set of core courses, including some at the advanced graduate level that provide the broad background in physics that is so important in the long run, specialized courses relevant to the research area of the student, and the research for the Ph D dissertation. Students entering with graduate level work at other institutions may include relevant courses taken at the other institutions in their proposal for candidacy, which includes all their course preparation as well as the research proposal for the dissertation. The Department of Physics at Lehigh University offers programs leading to the B.A. in astronomy, the B.S. in astrophysics, and to the B.A., B.S., M.S., and Ph.D. degrees in physics, as well as a summer research program for undergraduates. Research areas include astronomy and astrophysics, atomic, molecular, and optical physics, biophysics, computational physics, condensed-matter physics, general relativity, cosmology, and string theory, high-energy and accelerator physics, nano science, non-linear optics and photonics, plasma physics, soft-condensed matter and complex fluids, and statistical physics.
