Renowned radiologist Emeritus Professor Jan Lotz obtained his PhD in Applied Ethics from Stellenbosch University at the age of 78. The murder of his only daughter, Inge, in 2005 profoundly shaped his life. Teaching and mentoring young registrars became his source of purpose and healing, and his PhD thesis is dedicated to her. After suffering a traumatic brain injury and months of recovery, Lotz overcame significant physical and cognitive hurdles to complete his PhD.
