An innovator in genetics and molecular biology, Norman Arnheim has profoundly shaped our
understanding of the human genome. He revolutionized genetic research as a co-director of the
development of the polymerase chain reaction (PCR), a technique that allows scientists to copy
and study individual segments of DNA, and pioneered PCR methods enabling DNA analysis of a
single cell. This innovation opened new frontiers in the study of genetic mutation and
reproductive biology, leading to global advancements in medical diagnosis and personalized
medicine that have improved health care outcomes worldwide.
For nearly four decades, Professor Arnheim has been an outstanding role model for USC’s
scientific community, guiding students and colleagues with a balance of intellectual rigor and
personal warmth. His leadership in the department of biological sciences and his mentorship of
young scientists have created a thriving environment for discovery and collaboration. His
mentees speak highly of his generosity with time and ideas, his commitment to fostering their
growth, and his passion for pushing the boundaries of scientific knowledge.
Among his many accolades, Professor Arnheim is an elected fellow of the American Association
for the Advancement of Science. The throughline in all his achievements, however, is his deep
commitment to scientific and medical research with potential to radically improve our lives. This
credo has also helped guide and inspire countless scientists, as evidenced by the more than
51,000 citations he has garnered from over 180 publications.
Professor Arnheim’s work has propelled our ability to apply our scientific and technological
knowledge toward greater human thriving. He has helped establish the foundation for a healthier
21 st century, and his impact will resonate for generations to come.
