The Applied Physics and Materials Science Department at Caltech offers multidisciplinary graduate programs spanning engineering, physics, and materials science in which fundamental physical principles are used to address research issues of technological importance at the frontiers of engineering and science.

Research in the Department encompasses a diverse set of

topics at the forefront of engineering and science. These include photonics and optoelectronics, biophysics, solid-state electronic materials and devices, plasma physics, and amorphous and nanostructured materials. The research also encompasses the fundamental study of solid matter with the goal of engineering new materials with superior properties, and ultimately enabling altogether new types of devices.
