Tulio Valdez, MD, MSc
Professor of Otolaryngology - Head & Neck Surgery (OHNS) and, by courtesy, of Pediatrics
BioDr. Tulio A Valdez is a surgeon scientist with a subspecialty interest in Pediatric Otolaryngology. He attended medical school at Universidad Javeriana in Bogota Colombia before undertaking his residency in Otolaryngology, Head and Neck Surgery in Boston. He completed his Pediatric Otolaryngology Fellowship at Texas Children’s Hospital (2007), Houston and obtained his Master’s in Clinical and Translational Research at the University of Connecticut.
Clinically, Dr. Valdez has an interest in pediatric sleep apnea. He has a special interest in the management of sinus disease in cystic fibrosis. Dr. Valdez has co-authored one textbook and numerous book chapters and scientific manuscripts. Dr. Valdez continues his clinical research in these areas, particularly with a focus on aerodigestive disorders.
Scientifically, Dr. Valdez has developed various imaging methods to diagnose otitis media and cholesteatoma a middle ear condition that can lead to hearing loss. He was part of the Laser Biomedical Research Center at the Massachusetts Institute of Technology. His research includes novel imaging modalities to better diagnose ear infections one of the most common pediatric problems. His research has now expanded to include better intraoperative imaging modalities in pediatric patients to improve surgical outcomes without the need for radiation exposure.
Dr. Valdez believes in multi-disciplinary collaborations to tackle medical problems and has co-invented various medical devices and surgical simulation models. -
Carlos Valencia
Undergraduate, Mechanical Engineering
BioBorn in Camarillo, California, Carlos Valencia learned early that challenges forge resilience. As the son of a hard-working immigrant family, he spent summers working in the avocado and lemon industry—a childhood that taught him the value of grit and the power of opportunity. Today, as a Mechanical Engineering student at Stanford University, he channels that determination into robotics, education advocacy, and uplifting communities.
Carlos loves learning about robotic technology and has worked on numerous projects related to the field. Carlos’s passion for engineering took root in high school. As the former president of the ACHS MESA (Mathematics, Engineering, Science, & Achievement) chapter, he mentored 45+ first-generation students, leading them to compete in national STEM competitions. In the summer of 2024, he worked with L5 Automation, a robotics company based in La Cañada, CA, in Olmos, Peru where he helped develop harvesting platforms for one of the largest agriculture producers in Peru.
Beyond engineering, believes in the power of storytelling to inspire action. His TEDx talk, “Avocados Rot” drew from his upbringing to challenge audiences to seize fleeting chances—a message that resonated globally. Recognized as Camarillo Youth of the Year (2023) and awarded the Bronze Volunteer Award by the American Red Cross, he balances innovation with service, whether rebuilding communities after disasters or leading robotics teams.
Carlos’s mission is to democratize STEM access. Carlos envisions a world where education erases barriers. He aims to pioneer low-cost robotic solutions for agriculture and healthcare while expanding mentorship networks for first-gen students. When not engineering or volunteering, he unwinds by hiking, playing pickup soccer, or tinkering with 3D printers.
