Caltech is a small, highly selective institution, emphasizing research in the sciences and engineering. With undergraduate and graduate students each numbering less than 1,000, and over 280 faculty members, Caltech offers an exceptionally high level of faculty-student interaction. Caltech has one of the best mathematics departments in the country, and offers a very strong graduate program. Its mathematics faculty was ranked 11th in the US by the 1995 study by the National Research Council; in the 2006 U.S. News survey, the graduate program tied for 7th, ranking above those at Columbia, UCLA, and Cornell. In 2011, the Times Higher Education ranked Caltech the world's number one university displacing Harvard who held that spot for eight years.

The mathematics department has 15 regular faculty members, 12 postdoctoral fellows and instructors, and 29 graduate students. The graduate program in mathematics is designed to prepare students for research careers in universities, industry or government. Accordingly, only those students seeking the Ph.D. degree are admitted. In the past fifteen years, Caltech has awarded doctorates in mathematics to about 90 students, many of whom have moved into attractive positions as members of university faculty and in industry and government research.

Graduate students are encouraged to engage in creative research work after passing their qualifying exams (see below).  As a result of the informal atmosphere, small size of the department, and the large faculty to student ratio, graduate students have ample opportunity to interact closely with the faculty.  The research interests of the faculty as well as the courses and seminars offered are listed below.  Further details appear in the 2011-2012 catalog and online at .

Caltech has an excellent mathematics library of over 20,000 volumes and 250 mathematical journals.  Students have access to a wide variety of computing equipment in the computing center and to personal computers in the Mathematics building and other campus locations.
