The Computing and Mathematical Sciences (CMS) PhD program is a unique, new, multidisciplinary program at Caltech involving faculty and students from computer science, electrical engineering, applied math, economics, operations research, and even the physical sciences. The program sets high standards for admission and graduation, and boasts a broad collection of world-class faculty (any faculty at Caltech from any of the areas above can advise students). Disciplines across the information sciences are experiencing an unprecedented convergence. As different areas interact, new fields are emerging. For example, combining Computer Science with... ...Optimization and Statistics has led to machine learning, "big data," and the field of data science. ...Control and Electrical Engineering has led to the smart grid, smart buildings, and the internet of things. ...Physics has led to quantum computing and quantum information theory. ...Economics has led to algorithmic game theory, privacy, and the field of network science. ...Biology and Electrical Engineering has led to bioinformatics, molecular programming, and biomolecular circuits.
