UCSB has a decent Computer Science department. The department is smaller compared to the other UCs. Students get equal attention from faculties. Overall, UCSB campus is friendlier, you can adjust easily to the environment. US News ranking ranked the CS department of UCSB 28th in the country. 

The curriculum is a combination of basic programming, surveys of numerical methods, programming languages and compilers, automata theory, algorithm and data structures, etc. UCSB CS faculties are accomplished researchers and teach well. 

As per Payscale, CS graduates from UCSB earn around $76k - $137k. 

Being a small department, it isn’t good in all domains of CS. For instance, there aren’t any faculty members at UCSB who are pursuing research in hardcore Machine Learning. So, if you are interested in a particular area of CS, take it into consideration while choosing the institute. 

If you are considering pursuing a Ph.D. in Materials Engineering, the University of California, Santa Barbara (UCSB) is an excellent choice to consider. Here are some reasons why:

• Strong Research Culture: UCSB has a well-established materials engineering program with world-renowned faculty members who are leaders in the field. The program focuses on cutting-edge research in materials science and engineering and offers a wide range of research opportunities for students.
• State-of-the-Art Facilities: UCSB boasts state-of-the-art facilities and research centers, including the Materials Research Laboratory (MRL), which provides students with access to advanced characterization and fabrication facilities. These facilities are crucial for materials research, and students can expect to gain valuable hands-on experience working with these tools.
• Collaborative Environment: The materials engineering program at UCSB fosters a collaborative and interdisciplinary environment, which allows students to work with researchers across different departments and fields. This approach encourages students to develop a broad perspective on materials engineering and helps them to tackle complex problems that require a multidisciplinary approach.
• Career Prospects: A Ph.D. in Materials Engineering from UCSB can open up a range of career opportunities in academia, industry, and government research. Graduates from UCSB's materials engineering program have gone on to work for leading companies in the materials industry, as well as academic institutions and research labs.
• Lab Environment: When choosing a graduate school, the lab environment is a critical factor to consider. UCSB offers a diverse range of research labs, and you should carefully consider the lab environment and the research projects being undertaken by potential advisors.
• Advisor: The faculty advisor plays a crucial role in a graduate student's success. It is important to choose an advisor whose research interests align with your own, and who can provide you with the support and guidance needed to succeed in your research.
• Competitive Environment: It is worth noting that graduate school can be competitive, and UCSB is no exception. However, this is often a reflection of the high standards and expectations set by top universities. It is also worth noting that lab culture can vary depending on the advisor and the lab itself.
• Visit the School and Lab: To get a better sense of the environment and culture at UCSB, it is highly recommended that you visit the school and lab you are considering joining. This will allow you to meet with faculty and students, tour the facilities, and get a feel for the overall vibe of the program.

UCSB's materials engineering program offers a strong research culture, state-of-the-art facilities, a collaborative environment, and excellent career prospects. When considering UCSB for graduate school, it is essential to carefully consider the lab environment, and faculty advisor, and visit the school and lab to get a better sense of the overall culture.
