Biography

Waleed Elhelaly, Ph.D., is an Assistant Instructor of the Department of Internal Medicine at UT Southwestern Medical Center, and a member of its Division of Cardiology.

Originally from Egypt, Dr. Elhelaly received his medical degree from Ain Shams University in Cairo, and a master’s degree in Histology and Biochemistry from Cairo University in Egypt. He also earned his doctorate in Histology and Cytogenetics from Cairo University in Egypt. Dr. Elhelaly then traveled to conduct his postdoctoral research in the field of studying/enhancing cardiac regeneration under the mentorship of Sadek Hesham, M.D., Ph.D.

Dr. Elhelaly’s research interests include driving adult mammalian cardiomyocytes cell cycle-reentry through discovering novel transcriptional regulation pathways, exploring mammalian valve regenerative capacity. His investigations have resulted in 7 publications in peer-reviewed journals. Additionally, he has presented his findings at scientific conferences throughout the United States and around the world.

Dr. Elhelaly is active in several professional organizations, including The American Society of Echocardiography, and the American Heart Association, where he serves as a reviewer on the regenerative study section.

During his free time, he enjoys cooking, tennis, watching history documentaries, and spending time with his family.

Dr. Elhelaly believes in the deep impact environment can have on individual development, so the encouraging and cutting-edge science executed at UTSW is the perfect place for him to achieve his goals.
