Dr. Weng grew up in Plano, TX. Following graduation from Plano West Senior High School, he attended Cornell University and received a Bachelor of Science in electrical and computer engineering. He then moved to Cambridge, Massachusetts where he earned a PhD from the Massachusetts Institute of Technology. While working on his thesis research, which involved building instruments to detect the growth of single cancer cells, Dr. Weng came to the realization that he wanted to make a positive impact on the lives of cancer patients by leveraging his deep understanding and appreciation of technology to treat this complex disease. With multiple generations of his family living in the DFW area, it was an easy decision for him to return to Dallas. He earned his MD and completed his training as a chief resident in radiation oncology at the UT Southwestern Medical Center.
