2013 Evans Lecture
Jacqueline K. Barton, Ph.D.
Dr. Jacqueline K. Barton is the Arthur and Marian Hanisch Memorial Professor of Chemistry and Chair of the Division of Chemistry and Chemical Engineering at the California Institute of Technology. She is a native New Yorker. Barton was awarded the A.B. summa cum laude at Barnard College in 1974 and a Ph.D. in Inorganic Chemistry at Columbia University in 1978 in the laboratory of S. J. Lippard. After a postdoctoral fellowship at Bell Laboratories and Yale University with R. G. Shulman, she became an assistant professor at Hunter College, City University of New York. In 1983, she returned to Columbia University, becoming an associate professor of chemistry and biological sciences in 1985 and professor in 1986. In the fall of 1989, she joined the faculty at Caltech. In 2009, she began her term as Chair of the Division.
Professor Barton has pioneered the application of transition metal complexes to probe recognition and reactions of double helical DNA. She has designed chiral metal complexes that recognize nucleic acid sites with specificities rivaling DNA-binding proteins. These synthetic transition metal complexes have been useful in elucidating fundamental chemical principles that govern the recognition of nucleic acids, in developing luminescent and photochemical reagents as new diagnostic tools, and in laying a foundation for the design of novel chemotherapeutics. Barton has also carried out seminal studies to elucidate electron transfer chemistry mediated by the DNA double helix. She first showed that oxidative damage to DNA can arise from a distance through charge migration through the DNA duplex. She furthermore established that DNA charge transport chemistry is exquisitely sensitive to intervening perturbations in the DNA base stack, as with single base mismatches or lesions. This chemistry has since been applied in the development of DNA-based electrochemical sensors and explored in the context of long range signaling within the cell. Through this research, Barton has trained more than 100 graduate students and postdoctoral students, with about half in academic positions.
Barton has received numerous awards. These include the Alan T. Waterman Award of the National Science Foundation (1985), the American Chemical Society (ACS) Award in Pure Chemistry (1988), the ACS Eli Lilly Award in Biological Chemistry (1987), ACS Garvan Medal (1992), and the ACS Breslow Award in Biomimetic Chemistry (2003). She has also received the ACS Baekeland Medal (1991), the Fresenius Award (1986), the ACS Tolman Medal (1994), the Mayor of New York's Award in Science and Technology (1988), the Havinga Medal (1995), the Paul Karrer Medal (1996), the ACS Nichols Medal (1997), the Weizmann Women & Science Award (1998), the ACS Gibbs Medal (2006), the ACS Cotton Medal (2007), and the ACS Pauling Medal (2007). She was a fellow of the Sloan Foundation, a Dreyfus Teacher-Scholar, and an NSF Presidential Young Investigator. She is a recipient of a prestigious MacArthur Foundation Fellowship (1991) and she has been elected to the American Academy of Arts and Sciences (1991), the American Philosophical Society (2000), and the National Academy of Sciences (2002). She has received ten honorary degrees including Yale University (2005) and Columbia University (2010). She also received university medals from Barnard College (1990) and Columbia University (1992). She has also served the chemical community through her participation in ACS, government and industrial boards. Based upon her industrial board service, she was named an Outstanding Director by ODX (2006). In October 2011, Dr. Barton received the 2010 National Medal of Science from President Obama.
