Understanding how tumors respond to radiation has been a lifelong process for Puneeth Iyengar, M.D., Ph.D., Assistant Professor of Radiation Oncology at UT Southwestern Medical Center. He began testing theories in school science fairs as an adolescent growing up in Louisiana. Studying at MIT furthered his interest in the biologic and engineering aspects of medicine, and he earned a bachelor of science degree in biology before receiving his M.D./Ph.D. degrees from Albert Einstein College of Medicine in New York in 2005.
