The transition to academia allowed him to make links between theory, research and professional practice. He has experienced a wide variety of training in both policing and higher education, and values the practitioner-led approach to learning. Robert Ewin is a serving police officer, practitioner, and researcher, with experiences and publications around dealing with vulnerability within the criminal investigation setting.
