Dr. Swelum started his career in Egypt and maintains an ongoing affiliation with the university there, teaching and doing research on large animal Theriogenology. Dr. Swelum worked as Assistant Professor of Theriogenology at Zagazig University until 2010. He then accepted a position Assistant Professor of Theriogenology at King Saud University. He is now an associated professor and he founded the Theriogenology research team that providing clinical service and conducting research in animal reproduction. 

Dr. Swelum devoted most of his career to teaching Theriogenology and conducting applied research on animal reproduction. He served as the resident veterinarian and veterinary consultant to King Abdul-Aziz Arabian Horse Center and Germplasm Bank and Artificial Insemination center in Saudi Arabia. He received several awards recognizing his excellence in teaching, research quality and clinical practice including International Publication award from Zagazig University. Dr. Swelum provided large animal reproductive medicine continuing education programs for veterinarians around the world. He is the author of over 60 scientific research articles. Dr. Swelum is the author of one book and several book chapters on animal reproductive medicine. He is an active member of many societies and association as the International Embryo Transfer Society.
