"I feel most honored to receive the Mildred Cohn Award from the ASBMB. I also feel in debt to women like Mildred Cohn who paved the road for other women scientists and served as an example for us to follow. These are exciting times for the cryo-EM field, and I see this award as a tribute to how far this technique is taking us toward a mechanistic understanding of biological processes. I look forward to continuing using cryo-EM in our efforts to visualize large biological macromolecular assemblies at work."

- Eva Nogales

Eva Nogales at the University of California, Berkeley, has won the American Society for Biochemistry and Molecular Biology’s Mildred Cohn Award in Biological Chemistry for her revolutionary application of structural biology to molecular-level insights of essential large multiprotein complexes. The Cohn award honors scientists who have utilized physical approaches to make substantial advances in understanding biological chemistry.

Nogales is one of the preeminent leaders in the field of cryo-electron microscopy, or cryo-EM. Robert Tjian at the Howard Hughes Medical Institute wrote in support of Nogales’ nomination: “She has been bold, innovative and rigorous in applying negative stain and cryo-EM to solving 3-D structures of very challenging biological macro-molecules.” In his letter of support for Nogales’ nomination, Carlos Bustamante, Nogales’ colleague at Berkeley, said, “I can think of very few other scientists whose work has deepened and broadened our knowledge to anywhere near the same extent as Eva’s achievements have done.”

Nogales was trained as a physicist. She earned her bachelor’s degree in physics at the Universidad Autonoma de Madrid in Spain and completed her Ph.D. in biophysics in the physics department of Keele University in the U.K.

It was as a postdoctoral fellow in the laboratory of Kenneth Downing at the Lawrence Berkeley National Laboratory that Nogales made her first significant contribution to the field of structural biology. She used electron crystallography to generate an atomic structure of alpha and beta tubulin. This was not only an important advance for the field of cell biology but also a landmark achievement in structural biology, since alpha and beta tubulin had been resistant to X-ray crystallographic approaches. Microtubules and their interactions with other proteins have remained an important focus of Nogales’ research. She has published several seminal papers describing the structural basis of the complex dynamics of microtubules and their interactions with important regulatory proteins.

“Her work has been at the forefront of microtubule cytoskeleton research and has set Eva apart in the whole macromolecular EM field,” said Kenneth Downing, Nogales’ postdoctoral mentor at Lawrence Berkeley National Laboratory. “There is no question that she is recognized throughout the EM-structural biology community as one of its rising stars and leaders.”

Robert Glaeser of the University of California, Berkeley, emphasized Nogales’ many important contributions beyond her work on the cytoskeleton. “Prof. Nogales is a structural biologist of extraordinary accomplishment. She has made major contributions in several different topics of protein structure and function,” he said. Through continued refinement and development of advanced techniques, Nogales has been able to generate numerous impressive high-resolution structures of important multiprotein complexes including the CRISPR-associated complex, the 26S proteasome and the human transcription preinitiation complex.

Nogales is a Howard Hughes Medical Institute investigator and a member of the National Academy of Sciences. She has received the Protein Society’s Dorothy Crowfoot Hodgkin Award and the American Society for Cell Biology’s Early Career Award.

Nogales’ award lecture, “Atomic structures of microtubules in different states: towards a mechanistic understanding of dynamic instability,” will take place at 2:15 p.m. Monday, April 4, in Room 6B of the San Diego Convention Center.
