Parental Support Drives Biology Graduate on Road to Ph.D.

When Valeria Castellanos Rodriguez crosses the commencement stage next week, she will be thinking about the countless hours she logged in labs en route to a biology degree.

She'll be thinking about her primary Cal State San Marcos mentor, biology professor Carlos Luna Lopez. She'll be thinking about her impending enrollment at UC Irvine to begin a Ph.D. program in cancer research.

Mostly, though, she'll be thinking about her parents.

Rodriguez’s father and mother never got the chance to pursue higher education, with her dad stopping in sixth grade and her mom in first grade. Rodriguez grew up in Oceanside with three siblings, and for the first 18 years of her life, she and her entire family resided in a house owned by a relative. Her father would rise by 5 a.m. seven days a week to do landscaping work, and still it was barely enough to scape by.

Many parents in that situation would have urged their children to drop out of school to help earn money for the family, but Rodriguez’s parents thought differently.

“They have always supported my journey of higher education, which I’m very, very thankful for,” Rodriguez said. “They didn’t choose not to have an education. They didn’t have an opportunity to. My mom used to tell me that if she could have gone to college, she would have become a nurse.”

On her path to a science degree, Rodriguez benefited from more than just parental support. She had a sibling role model in her sister, Tanya, who’s only one year older and resembles Valeria so much that they’re often mistaken for twins. Tanya preceded Valeria at CSUSM (graduating in 2024) and, after taking a gap year, also will be starting a Ph.D. program in the fall, at UC Santa Cruz for immunology.

Then there was her high school. Rodriguez had the advantage of attending Mission Vista, the newest high school in Vista Unified School District, which offers a program called Project Lead the Way that allows students to get a head start in STEM disciplines like biomedicine and engineering.

As a result, Rodriguez arrived at CSUSM having been exposed to and liking science, specifically biology. It was at CSUSM, however, that she discovered research and the notion – previously unimaginable to her – that research could be a career.

After her freshman year, she joined the lab of Luna, the biology professor, for the Summer Scholars program in 2022. She wanted to do research involving the human body, and she liked that Luna specialized in breast cancer research.

Rodriguez has been a member of Luna’s lab ever since. She worked on a project to learn how different types of fat cells (brown and white) affect how breast cancer spreads, growing such cells in the lab and using a special microscope to examine how they change shape. She also helped the tab transition to employing 3D models to study breast cancer cells since, as she points out, “humans are 3D, so hopefully we make research a lot more relevant if we use a model that’s closer to us.”

“Dr. Luna is the best mentor I’ve ever had,” Rodriguez said. “He’s very honest when it comes to meeting realistic goals but also supports me in the path that I want to follow. And he’s a very fun guy.”

After she caught the research bug through Summer Scholars, Rodriguez set her sights even higher for the subsequent two summers, gaining acceptance to premier undergraduate research programs through Stanford University and the Fred Hutch Cancer Center in Seattle.

Outside of the lab, she became heavily involved with both the Center for Training, Research and Educational Excellence (CTREE) – the hub for research-based initiatives at CSUSM – and The Alliance, a program aimed at increasing access to college education for area K-12 students. She also maintained a 3.96 GPA while being honored as one of the first two CSUSM students ever to receive a Barry Goldwater scholarship, a prestigious national award that recognizes leadership potential in research science.  

Of being a first-generation Latina scientist, Rodriguez said: “It has been difficult. Sometimes I feel like I’m behind, like I’m sprinting a marathon rather than jogging it. But I think I’ve learned to appreciate the small moments, whether it’s winning an award, having a happy time with my family and friends, or just chatting about life with Dr. Luna. Those moments motivate me to continue and overcome the hardships that I’ve gone through.”

Luna and Denise Garcia, the director of CTREE, said Rodriguez is one of the most motivated and talented students they’ve encountered in their careers as professors.

“I put her in the top 1% of students that I’ve worked with,” Luna said. “She displays a great deal of dedication, intellectual capacity and compassion. She is driven to be a leader and role model in the field of cancer research.”

The drive is innate in Rodriguez. It was forged as a child as she watched her parents struggle to assimilate into American culture and establish a livelihood. It carried her through her high school years amid the COVID-19 pandemic, when her whole family was stuck inside the rented room, which simultaneously brought them closer together and drove them crazy.

Now, with her family having moved out and living in their own apartment, that inner drive will propel Rodriguez toward a doctorate in UC Irvine’s Cellular and Molecular Biosciences program, which she could start as soon as next month.

“I’ve always been motivated to get a college degree and a Ph.D.,” she said. “Yes, I want to have a better life for myself, but more importantly, I want to thank my parents and make them proud.”
