Raphael obtained his initial medical degree from the University of Western Australia (UWA) in 1996 and spent his formative years at Royal Perth Hospital (RPH). After working as a volunteer surgical registrar at the major teaching hospital in Kathmandu (Nepal), a term as a relief registrar in radiation oncology at RPH sparked a passion and prompted a change in career direction.

Raphael initially trained in radiation oncology at Sir Charles Gairdner Hospital (SCGH), completed his training at the Peter MacCallum Cancer Centre in Melbourne. Followed by a fellowship in image-guided radiation therapy and brachytherapy at the Austin Hospital in Victoria, he returned to SCGH in 2009 and was head of the Department of Radiation Oncology from 2011 to 2013. Raphael then moved to GenesisCare where he is currently the medical director at Shenton House in Joondalup. He also works as a consultant at Fiona Stanley Hospital and conducts a clinic in Geraldton once a month. 

Raphael is one of only two specialised gynaecological radiation oncologists in Western Australia. He is also an active committee member in the Faculty of Radiation Oncology, the Royal Australian and New Zealand College of Radiologists (RANZCR), adjunct associate professor at the School of Medical and Health Sciences at ECU, assistant professor at the School of Surgery at UWA, and a reviewer for the Journal of Medical Imaging and Radiation Oncology.
