The kind of Emphasis that is being proposed here, at the M.S. and Ph.D. level across a broad collection of Departments and with a strong emphasis on engineering and science based on the second model, is not currently in place within the UC system.
A number of UC campuses offer specializations in CSE in various departments, however to the best of our knowledge no coordinated emphasis at the M.S. and Ph.D. levels currently exists. UC Berkeley has a collection of M.S. degrees in engineering and science departments with a specialization in computational science. The core courses are similar to the ones proposed here. UCLA has a graduate specialization in Scientific Computing in the Department of Computer Science. UCSD has a specialization in science applications in the Ph.D. program in the Department of Mathematics.
UC Davis has proposed to create a Department of Computational Science and Engineering. This is different from what we have proposed here, as it would be a separate Department granting degrees in Computational Science and Engineering. To ensure that students are fully grounded in a traditional science or engineering discipline as well as in the fundamental tools and algorithms of Computational Science, and because the job market for students with a separate degree in CSE is untested, we have instead proposed an Emphasis in CSE for UCSB.
The Faculty Senate at UC Berkeley has recently approved an undergraduate program in Computational Science and Engineering which is expected to attract around 20-30 engineering undergraduates per year.
