Overview

I graduated from the US Naval Academy in 1983 and served as a nuclear-trained officer on board two submarines before shifting to the Navy Medical Corps. Following medical school, I completed Diving Medical Officer training and served as head of diving research at the Naval Medical Research Center. After completing specialty training, I completed my 30+ year Navy career as Head, Radiation Oncology at Naval Medical Portsmouth Virginia. After returning to Duke, I served two years as Medical Director, Danville Center for Radiation Oncology, where I helped introduce technological advances into the clinical setting designed to improve treatment precision while minimizing treatment-related side effects. I joined Duke’s Wake County Radiation Oncology team in June 2017, and see patients in Raleigh and Cary. My clinical focus is on multi-disciplinary treatment of gynecologic, genitourinary, and lower gastrointestinal malignancies, with a focus on quality-of-life through minimizing treatment-related side effects.

I specialize in gynecological radiation oncology but also treat patients with cancer of the breast, brain and central nervous system among others. I also have a special clinical interest in brachytherapy, when radiation is delivered directly to the target internally. Duke is a world leader in treating gynecological cancers with all forms of treatment. I have the privilege of collaborating with many other specialists in gynecologic surgery, chemotherapy and pathology. We have built a state of the art gynecologic cancer program in radiation therapy with a dedicated brachytherapy suite with built-in anesthesia monitoring, imaging to allow for the most complex and pinpoint treatments to treat tumors, while sparing all normal tissue. My mother was a radiation oncologist. Growing up, her dedication to her patients inspired me. She developed truly, caring relationships and touched the lives of so many people over the decades of her practice. My wife, my two children and I currently live in Durham and have been happy members of the Duke community since 2005. Outside of medicine, I spend as much time with them as I can. Dr. Chino is rated as a Distinguished provider by MediFind in the treatment of Endometrial Cancer. His top areas of expertise are Cervical Cancer, Endometrial Cancer, Vulvar Cancer, and Neuroendocrine Carcinoma of the Cervix.

I am a radiation oncologist with a particular focus on the management of women's health malignancies. I specifically work with breast and gynecologic cancer patients. I believe a critical part of patient care is appreciating where patients are during this difficult time, and providing them with the tools and understanding they need to both feel comfortable and make informed decisions. My job provides me with the opportunity to really get to know my patient’s on a personal level. It’s one of the parts I enjoy most about my job: understanding and appreciating who the patient is beyond their diagnosis, and working towards what matters most to them. Outside of my clinical work, I enjoy spending time with family and helping my young children discover the world around them. Dr. Ayala-Peacock is rated as an Advanced provider by MediFind in the treatment of Endometrial Cancer. Her top areas of expertise are Cervical Cancer, Endometrial Cancer, Neuroendocrine Carcinoma of the Cervix, and Vulvar Cancer.
