当前的研究包括在RHIC（STAR）的电磁跟踪器上进行相对论重离子碰撞研究，以及在Brookhaven国家实验室进行sPHENIX实验。该研究领域致力于在极端温度，密度和压力条件下的物质研究，在这些条件下，构成正常核物质的夸克和胶子不再局限于强子。这种限定的物质称为夸克胶子等离子体（QGP），实验使用高能探针（例如粒子射流和重味夸克）来确定夸克和胶子如何在这种介质中损失能量.PhD程序包括一组核心课程，包括某些高级研究生课程，这些课程提供从长远来看非常重要的物理学背景，与学生研究领域相关的专业课程，以及博
Current research involves the study of relativistic heavy-ion collisions at the Solenoidal Tracker at RHIC (STAR) and sPHENIX experiments at Brookhaven National labs. This field of research focuses on the study of matter under extreme conditions of temperature, density, and pressure, where the quarks and gluons that make up normal nuclear matter are no longer confined into hadrons. This deconfined matter is called the quark gluon plasma (QGP), and experiments use high-energy probes, such as particle jets and heavy flavor quarks, to determine how quarks and gluons lose energy in this medium.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.
