# Laura L. Kiessling

Laura Lee Kiessling (born 21 September 1960) is an American chemist and the Novartis Professor of Chemistry at the Massachusetts Institute of Technology. Kiessling's research focuses on elucidating and exploiting interactions on the cell surface, especially those mediated by proteins binding to carbohydrates. Multivalent protein-carbohydrate interactions play roles in cell-cell recognition and signal transduction. Understanding and manipulating these interactions provides tools to study biological processes and design therapeutic treatments. Kiessling's interdisciplinary research combines organic synthesis, polymer chemistry, structural biology, and molecular and cell biology.

## Education

Kiessling earned a B.S. in chemistry from the Massachusetts Institute of Technology in 1983 and a Ph.D. in chemistry from Yale University in 1989. At Yale, she worked with Stuart Schreiber to synthesize and study small molecules as probes of biological function. After earning her PhD, Kiessling spent two years at the California Institute of Technology as an American Cancer Society Postdoctoral Fellow, where she worked with Peter B. Dervan to study DNA recognition and cleavage.

## Career

In 1991, Kiessling joined the faculty of the University of Wisconsin–Madison, where she became the Steenbock Professor of Chemistry and the Laurens Anderson Professor of Biochemistry. While at UW-Madison, Kiessling also became the director of the Keck Center for Chemical Genomics and the National Institutes of Health Chemistry-Biology Interface Training Program. In 2017, she moved to the Massachusetts Institute of Technology as the Novartis Professor of Chemistry. as well as the editor-in-chief of ACS Chemical Biology.
Kiessling's contributions span the fields of organic synthesis, polymer chemistry, and molecular biology. She has made contributions to the synthesis and study of many biologically active molecules, including glycosyl donors, modified peptides, and glycopolymers. Kiessling's research has used these molecules to probe cell recognition and signal transduction processes (Figure 1). Her research has shown that multivalent ligands (molecules that possess multiple binding groups) can influence receptor-ligand binding mechanisms, activate signaling, and target specific immune responses. These discoveries have potential applications in targeted immunotherapy and disease treatment.
Kiessling has received a number of awards and honors in recognition of her research. She received a MacArthur Foundation Fellowship (popularly called the "MacArthur genius grant") in 1999. In 2007, Kiessling was inducted as a member of the United States National Academy of Sciences and in 2017, she received the Tetrahedron Prize for Creativity in Organic Chemistry.
Kiessling is a Fellow of the American Association for the Advancement of Sciences and the American Chemical Society, as well as an elected member of the American Academy of Arts and Sciences, American Philosophical Society, and American Academy of Microbiology. Since 2005, she has served as the founding editor-in-chief of ACS Chemical Biology. Kiessling is also the cofounder of Quintessence Biosciences, a company that is working to translate her technological advances into cures for various diseases. She has been selected as one of the fifty top research and development "Stars to Watch" by Industry Week.
