Narrowly escaping the Khmer Rouge after his parents and two siblings were killed during the civil war, he graduated in France, then obtained a scholarship at University of California, San Francisco, and moved to McGill University in Canada.

His involvement with Angkorian research started in 2000, when  French archaeologist Christophe Pottier asked for his expertise while excavating the site of the 8th-century Prey Khmeng temple in Siem Reap province, and was looking for an expert to do a preliminary study on them. Dr Chhem analyzed the skeletons recovered on that site, performing CT scans on them. This contribution triggered his interest in pre-Angkorian and Angkorian medicine.

After joining the excavation of one of the one of the 102 hospitals that King Jayavarman VII (1181-1218) ordered to be built in the late 12th century, Dr Chhem established the existence of a comprehensive, free state healthcare system within the Khmer Empire.
