As part of Professor Sidhu's commitment to the development of Endocrine Surgery, on a national and international level, he is involved with the training and mentorship of Endocrine Surgical Fellows. Fellows are surgeons who have obtained their exit exam in General Surgery, spend 1-2 clinical years in thyroid, parathyroid and adrenal surgery training and sometimes up to 3 research years examining causes for and new treatments for thyroid cancer and adrenal cancer. This allows the Fellows to gain further experience in the technical aspects of surgery on the thyroid, parathyroid, adrenal, and salivary glands and investigating the molecular and translational aspects of the thyroid and adrenal cancers that he or she treats.
