Professor McGurk has completed significant research in his field and focused on the early diagnosis of head and neck cancer, complications of surgery, and the use of minimally invasive surgery for head and neck cancer. He has written two books on salivary disease and influenced the practice of salivary gland surgery to move from excision to gland preservation. He also led a European trial on sentinel node biopsy which led to a 75% reduction in neck dissection for early mouth cancers. In addition, he developed a new way to treat odontogenic tumours (ameloblastoma) which preserves the mandible and normal facial appearance.
