91ÑÇÉ«´«Ã½

, a professor at the University of Pittsburgh, has won the 2019 Mildred Cohn Award in Biological Chemistry from the 91ÑÇÉ«´«Ã½ for her work in nuclear magnetic resonance spectroscopy. This award recognizes scientists who have developed innovative physical approaches to advance the field of biological chemistry.

 

“I am deeply grateful and very pleased to have been nominated and selected for the 2019 Mildred Cohn Award from the 91ÑÇÉ«´«Ã½. Mildred Cohn was one of the first women in NMR and pioneered its use to study enzymatic reactions. She was daring and undeterred, overcoming countless obstacles during her long life. It’s an honor to receive this award named after such a tremendous scientist.”

— Angela Gronenborn

, a professor at the University of Delaware, nominated Gronenborn for the award, writing, “Professor Gronenborn’s pioneering contributions to the field of biological chemistry are remarkable in their vision, creativity and intellectual depth.”

Gronenborn chairs the department of structural biology at the University of Pittsburgh School of Medicine. Her research group combines NMR spectroscopy with biophysics, biochemistry and chemistry to investigate cellular processes at the molecular and atomic levels to understand human disease. Major focuses of her lab include protein-carbohydrate recognition, HIV pathogenesis and protein deposition diseases.

Gronenborn became interested in NMR spectroscopy during her graduate training at the University of Cologne. Throughout her career, she has transformed and expanded the applications of NMR spectroscopy to determine the structure of biological macromolecules. Her work includes nearly 500 peer-reviewed articles, including several landmark publications that opened the door for modern triple-resonance NMR experiments.

In 1988, Gronenborn joined the National Institutes of Health where, alongside Marius Clore and Adriaan Bax, she started to work on HIV, supported by the HIV-targeted antiviral program. She pushed the boundaries of NMR spectroscopy by developing new technologies to determine the structures of proteins and protein complexes larger than 20 kilodaltons, a feat the scientific community considered impossible at the time.

  wrote in his letter of support for Gronenborn’s nomination, “Her work, both in quantity and depth, continues to define and extend the limit of macromolecular NMR.”

Gronenborn’s current work aims to understand how HIV hijacks the host cell machinery for replication by determining complexes of viral and cellular proteins. She combines computational tools from chemistry and physics with her expertise in NMR spectroscopy and X-ray crystallography to analyze HIV biology.

, a professor at the Massachusetts Institute of Technology, wrote in his letter supporting Gronenborn’s nomination, “Her research continues to push the technological boundaries for determination of structure and dynamics of large complexes of HIV assemblies with human proteins.”

In addition to her research achievements, Gronenborn has been honored for her devotion to the scientific community. She has trained more than 60 Ph.D. students, postdoctoral researchers and undergraduate students during her academic career. She also has chaired multiple international scientific conferences, and she serves in editorial roles for a number of journals. In 2007, Gronenborn was elected to the National Academy of Sciences for her outstanding contributions to research.

Gronenborn will receive her award at the 91ÑÇÉ«´«Ã½ annual meeting during the Experimental Biology 2019 conference in Orlando, where she will deliver an award lecture on “The awesome power of Fluorine NMR” at 9 a.m. April 17 in Valencia Ballroom A at the Orange County Convention Center.
