Biography
Hearn attended the University of Adelaide for his bachelor's degree, graduating in 1958. He attended the University of Cambridge for his PhD in theoretical physics and graduated in 1962. From 1962 to 1964, he was a research associate in physics at Stanford University, returning as an assistant professor and Sloan Research Fellowship, Sloan Foundation Fellow in 1965 after a year at the Rutherford Laboratory in England. While at Stanford, he worked with Sidney Drell and formulated the Gerasimov-Drell-Hearn sum rule for connecting the Compton scattering amplitudes to the inclusive Cross section (physics), photoproduction cross sections in particle physics. In 1969, he joined the faculty at the University of Utah as an associate professor of physics and became full professor in 1971. Around this period he began using ideas and tools from computer science to help solve problems symbolically in high energy physics. From 1973 until 1980, he was professor and chair of the University of Utah School of Computing. He joined RAND Corporation in 1980 as head of the Information Sciences Department, where he served until 1984. He worked at the National Science Foundation as a member of the Program Advisory Committee for the Office of Advanced Scientific Computing from 1984 to 1986. He was a resident scholar at RAND from 1990 to 1996.References
