Daisy Nunez Valenzuela
I am a third-year Biological Sciences student at CSU East Bay with a concentration in Cell and Molecular Biology, driven by a strong interest in understanding how cells function and how that knowledge can be applied in the field of dermatology. My goal is to help individuals who struggle with skin conditions such as acne or rashes regain confidence and improve their quality of life. Alongside my academic journey, I have worked at In-N-Out Burger for five years, where I have developed strong leadership, communication, and problem-solving skills in a fast-paced environment. These experiences have shaped me into a resilient and adaptable individual, prepared to thrive in healthcare settings. As I continue pursuing my degree, I am eager to gain hands-on experience through internships and shadowing opportunities in dermatology offices, where I can begin bridging my classroom knowledge with real-world patient care

Sooyun Cho
Sooyun Cho is a senior at the University of California, Berkeley, majoring in Molecular and Cellular Biology. After graduating in the fall of 2025, she plans to pursue a DDS degree while continuing her passion for immunology research, particularly as it relates to dentistry. Her current research focuses on identifying immune cells that develop resistance to immunotherapy, an important area of study for patients who often do not respond to such treatments in clinical settings. She hopes this scholarship will support her ongoing summer research in an immunology lab and help fund her participation in delivering an oral presentation at ABRCMS.
