The undergraduate program in mechanical engineering is accredited by the Engineering Accreditation Commission of ABET, 111 Market Place, Suite 1050, Baltimore, MD, 21202-4012 – telephone: (410) 347-7700. We offer a balanced curriculum of theory and application, involving: preparation in basic science, math, computing and writing; a comprehensive set of engineering science and laboratory courses; and a series of engineering design courses starting in the freshman year and concluding with a three course sequence in the senior year. Our students gain hands-on expertise with state-of-the art tools of computational design, analysis, and manufacturing that are increasingly used in industry, government, and academic institutions. In addition, the Department has a 15-unit elective program which allows students to gain depth in specific areas of interest, while maintaining appropriate breadth in the basic stem areas of the discipline. All students participate in a widely recognized design project program which includes projects sponsored by industry, UCSB researchers, as well as intercollegiate design competitions. The project program has been expanded to emphasize entrepreneurial product-oriented projects.
We offer an education that prepares our students to become leaders of the engineering profession and one which empowers them to engage in a lifetime of learning and achievement.
Educational Objectives for the Undergraduate Program
It is the objective of the Mechanical Engineering Program to produce graduates who:
- Successfully practice in either the traditional or the emerging technologies comprising mechanical engineering;
- Are successful in a range of engineering graduate programs including those in mechanical, environmental and materials engineering;
- Have a solid background in the fundamentals of engineering allowing them to pass the Fundamentals of Engineering examination;
- Are active in professional societies.
In order to achieve these objectives, the Department of Mechanical Engineering is engaged in a very ambitious effort to lead the discipline in new directions that will be critical to the success of 21st century technologies. While maintaining strong ties to stem areas of the discipline, we are developing completely new cross-cutting fields of science and engineering related to topics such as: microscale engineering and microelectrical-micromechanical systems; dynamics and controls and related areas of sensors, actuators and instrumentation; advanced composite materials and smart structures; computation, simulation and information science; advanced energy and transportation systems; and environmental monitoring, modeling and remediation.

Qualified students who wish to pursue advanced engineering education may enroll in the M.S. or Ph.D. programs. The department offers programs leading to the degrees of master of science and doctor of philosophy, with a specialization in any of the following major areas: dynamical systems and controls; computational science and engineering; solid mechanics and structures, thermo-fluid sciences and materials; micro/nanoscale science (including MEMS). The curricula for all of the major areas emphasize education in broad principles and fundamentals. At the same time, programs of study and research are flexible and tailored to accommodate the individual needs and interests of the students. Interdisciplinary approaches are stressed, and students are encouraged to cross over traditional boundaries into other departments.
The M.S. program is intended to extend and broaden the undergraduate background and equip practicing engineers with state-of-the-art knowledge in their field. The degree may be terminal or obtained on the way to the Ph.D. The Ph.D. program is designed to prepare students for careers in research and/or teaching in their area of specialization.
Mechanical engineering graduates at all levels are highly sought after by the automotive, aircraft, marine, defense, electronics, and materials manufacturing industries. Under the direction of the Associate Dean for Undergraduate Studies, academic advising services are jointly provided by advisors in the College of Engineering, as well as advisors in the department. In addition, departmental advisors are assigned to all students in the freshman year. A faculty advisor assists the students in the selection of departmental elective courses and provides counseling to students on a variety of issues related to their academic experience. Individual faculty are also available for help in program planning and professional development. A faculty supervisor and the graduate advisor, in conjunction with a graduate studies committee, direct the program of studies for M.S. and Ph.D. candidates. Undergraduate students enrolled in other majors at UCSB who plan to change to a major in the Department of Mechanical Engineering should obtain counseling from the departmental academic advisor.
