I am a pediatric endocrinologist with a diverse background and training. I am committed to providing high-quality care to patients and families with endocrine diseases, and teaching future generations of physicians. I have a great interest in the areas of neuroendocrinology, thyroid, endocrine effects of cancer and its treatment, especially oncofertility. This is where I have focused my efforts, allowing me to gain significant experience in both clinical and research arenas in this area. Using a multidisciplinary approach, I have collaborated with different specialties involved in the care of these conditions, optimizing patient care, carrying out clinical research, and developing guidelines and best practices. My goal is to continue to work in both clinical and scientific arenas, striving to advance the field of pediatric endocrinology.
