A Message from the Dean for the 2025-26 School Year

Year in review, commencement recap and highlighting outstanding members of the College
The 2025-26 academic year is now over, and there is much to celebrate!
The SDSU College of Sciences plays a critical role in boosting STEM research and teaching at San Diego State University. This year marks another step in advancing the university’s footprint, particularly among the local community’s booming biotechnology sector, as construction on the new life sciences building propels the facility toward its planned opening during the 2027-28 academic year.
Students, faculty and staff consistently reach new heights of research excellence — studying ancient Indigenous landscapes under the sea, making discoveries to help improve gut health, creating 3D bioprinted tumor models to transform cancer treatment, driving a new law to protect the health of homebuyers, uncovering a potential breast cancer treatment and much more.
Other exciting updates from the past year include professor Richard Levine delivering SDSU’s 2026 Albert W. Johnson Research Lecture and 2026 graduate and cancer researcher Bianca Rollbusch earning the California State University (CSU) Trustees' Award for Outstanding Achievement. The college is also proud to impact the local community through extensive outreach such as the annual San Diego Festival of Science and Engineering.
As the school year ends, we celebrate the current students, faculty and staff whose achievements and dedication to their fields allow the College of Sciences to reach new heights, as well as our alumni who make their mark on the local community and around the world. And, as ever, we are grateful for our generous donors who make these advancements possible.
Below are more updates from the College community.
Commencement Recap

The College of Sciences was home to three of the top 10 most popular majors for 2026 graduates: Psychology, computer science and biology.
This year, the College awarded nearly 1,500 undergraduate degrees across 34 majors in eight academic departments, in addition to 300 graduate degrees. Our graduates were among more than 13,600 degree candidates from across the university and became members of the more than 500,000 SDSU alumni around the world.
We were also delighted to bestow a doctor of science honorary degree to Greg Lucier, a longtime business leader in San Diego’s biotech and health care industries and a supporter of SDSU’s Guardian Scholars program.

Robert Mangan
Emeritus Staff, Department of Biology
Mangan was an SDSU alumnus, graduating in 1977 with a degree in botany and contributing more than 45 years of service to the university. Though he retired in December, he still returned weekly as a volunteer. Sadly, Mangan passed away in April but his memory lives on in the hundreds of plants he cultivated, the many faculty, students and staff he worked with on campus, and the great impact he made in the department of biology and university as a whole.
Congratulations to the Class of 2026 and to all of our faculty, staff and students on an incredible year!

College of Sciences Dean
