Caltech, the program in Mechanical Engineering is small, highly selective, and research oriented. Admission is preferentially granted to applicants who ultimately intend to pursue the Ph.D. degree.<br><br>Ph.D. graduates in Mechanical Engineering have gone on to successful careers both in industry and in academia. Among recent graduates, approximately 30% entered tenure-track academic positions upon graduation, 50% went into industry, and 20% entered postdoctoral research programs. Some of our recent Graduates currently hold tenure-track or tenured faculty positions at MIT, Princeton, Purdue, Johns Hopkins, UCLA, U. Texas (Austin), U. Michigan, U. Pennsylvania, Carnegie Mellon, and other universities worldwide. Graduates who choose an industrial career find employment both in large firms (primarily in the aerospace, energy, and semiconductor industries) and with small high-technology startup companies.<br><br>Virtually all graduate students in Mechanical Engineering receive financial support for the duration of their studies, which fully pays tuition and provides a stipend for living expenses. This support may take the form of a fellowship, a teaching assistantship, a research assistantship, or a combination of these options.
