How do foundational scientific inquiry and dedicated public service, nurtured through rigorous academic pursuit, ultimately shape our understanding of the universe and profoundly improve human lives? This overarching question finds compelling answers in the careers of the three distinguished individuals recently honored by the UC Santa Cruz Science Division for their 2026 Science Division Distinguished Alumni Awards. Gregory Reyes, Larry de Ghetaldi, and Nicholas Suntzeff represent the breadth of impact emanating from a commitment to science, spanning fields from biomedical research to healthcare policy and observational cosmology.
From Viral Detection to Cosmic Expansion
The narrative of scientific progress is often one of incremental breakthroughs, built on years of dedicated effort. Dr. Gregory Reyes, recipient of a Distinguished Undergraduate Alumni Award, exemplifies this through his 30-plus-year career in biotechnology and pharmaceutical research. A first-generation college student who graduated summa cum laude from UC Santa Cruz in 1976, Dr. Reyes went on to earn M.D. and Ph.D. degrees from Johns Hopkins University. His contributions moved beyond mere discovery; he helped pioneer methods for detecting viral genomes, a fundamental step in understanding and combating infectious diseases. Furthermore, he co-discovered and characterized the hepatitis E virus, and significantly contributed to the development of Victrelis, a key drug for hepatitis C, alongside advancing early HIV therapies targeting CCR5. This is not merely about identifying diseases, but about the painstaking work of developing the tools and treatments that directly alleviate suffering. His nearly 100 publications and 50 patents underscore a career dedicated to translating scientific understanding into tangible medical solutions.
Advocating for Equitable Healthcare
While Dr. Reyes’s work focused on the frontiers of biological science, Dr. Larry de Ghetaldi, who will posthumously receive a Distinguished Undergraduate Alumni Award, dedicated his life to ensuring scientific and medical advancements reached all who needed them. Dr. de Ghetaldi, a Santa Cruz family physician for decades, became a nationally recognized advocate for reforming Medicare’s geographic payment system. This critical work aimed to improve reimbursement equity for California physicians, addressing a systemic issue where regional variations in payment could impact access to care. His advocacy was not about simply raising rates, but about rectifying disparities within the complex framework of national healthcare policy. While headlines might broadly laud efforts to "fix Medicare," Dr. de Ghetaldi's specific, impactful contribution was to meticulously identify and work towards rebalancing payment structures, thereby strengthening the medical infrastructure that serves communities. His passing in August 2025 at age 69 leaves a legacy of tireless dedication to healthcare justice.
The Collaborative Nature of Breakthroughs
The grandest scientific questions often require monumental collaborative efforts, a truth powerfully illustrated by the work of Dr. Nicholas Suntzeff, recipient of the Distinguished Graduate Alumni Award. Dr. Suntzeff, who earned his Ph.D. in astronomy and astrophysics from UC Santa Cruz in 1980, co-founded the Calán/Tololo Supernova Survey and the High-Z Supernova Search Team. Their groundbreaking work on Type Ia supernovae provided the observational evidence that led to the discovery of the accelerating universe. This wasn't merely a theoretical postulation but a finding rooted in meticulous observation and analysis of cosmic phenomena, fundamentally altering our understanding of the universe’s expansion. It is crucial to note that Dr. Suntzeff’s work was a foundational contribution to the discovery that led to the 2011 Nobel Prize in Physics awarded to his collaborators, underscoring the team-based nature of modern astrophysical research rather than a singular individual achievement. His efforts also helped establish precise methods for measuring cosmic distances and the Hubble constant, critical benchmarks in cosmology.
The Enduring Legacy of Inquiry
The achievements of these three alumni, while diverse in their specific domains, collectively highlight the profound and multifaceted impact of scientific education and unwavering dedication. From the precise methodologies of viral detection and the complex policy negotiations of healthcare reform to the vast cosmic distances measured by supernova research teams, their careers demonstrate that the pursuit of knowledge at institutions like UC Santa Cruz fosters individuals capable of transformative contributions.
Limitations to consider in appreciating such accomplishments include the extensive timelines often involved in scientific and policy change. Viral treatments, healthcare system reforms, and cosmological discoveries are rarely instantaneous; they are the result of decades of research, advocacy, and collaborative effort. These awards celebrate not just a moment of discovery, but a sustained commitment to pushing boundaries and serving society.
As Dean of Science Bryan Gaensler aptly stated, these alumni represent "the very best of UC Santa Cruz’s commitments to groundbreaking research and profoundly impactful public service." The next steps in research across these fields will continue to build upon such foundations. In biotechnology, the ongoing quest for new viral therapies and diagnostic tools remains paramount. In healthcare, the push for equitable access and efficient systems is a perpetual challenge. And in cosmology, the implications of an accelerating universe continue to drive new theories and observations, probing the very nature of dark energy. The annual recognition of such extraordinary accomplishments, celebrated this year at a private ceremony at the Cowell Ranch Hay Barn on May 28, serves as a powerful reminder of the enduring value of scientific inquiry and public service, inspiring future generations to embark on their own journeys of discovery and impact.
